We utilize an open parameter set for our equipment to push our DMLM and DMLS, or direct metal laser melting and direct metal laser sintering, machines. [1] Direct Metal Laser Sintering (DMLS) is an Additive Manufacturing method that builds prototype and production metal parts using a laser to selectively fuse a fine metal powder. [2] From prototyping to making test parts, or even low-volume production runs, Direct Metal Laser Sintering should be part of your manufacturing process portfolio to consider. [2] Direct Metal Laser Sintering can therefore produce parts using metal alloys, whereas SLM can only produce single element metals such as aluminium and titanium. [3] Paperless Parts instant quotes Direct Metal Laser Sintering parts (DMLS). [4] Direct Metal Laser Sintering (DMLS) uses a high-powered laser to melt powdered layer by layer to build up your design. [5] Direct Metal Laser Sintering (DMLS) is a direct metal laser melting (DMLM) or laser powder bed fusion (LPBF) technology that accurately forms complex geometries not possible with other metal manufacturing methods. [6] A metal part used to replace a part of missing skull, created with Direct Metal Laser Sintering. [3] Eos is the global technology and quality leader for high-end solutions in the field of additive manufacturing (AM). eos is a pioneer and world leader in the field of direct metal laser sintering (DLMS) and provider of highly productive additive manufacturing systems for plastic materials. [7] While each project is different and has different requirements, we thought it would be helpful to run a quick post about the most popular applications and advantages of Direct Metal Laser Sintering (DMLS). [2] As mentioned in the beginning, Direct Metal Laser Sintering (DMLS) may not be the right fit for your particular project or application. [2] Direct Metal Laser Sintering is different to technologies such as Fused Deposition Modeling in that it doesn't use filament. [3] Before you can remove the object from the build platform, heat treatments are required with Direct Metal Laser Sintering. [3] Direct Metal Laser Sintering is heavily used in industries such as the aerospace and automotive sectors. [3] Unlike with Stereolithography or FDM, removing supports with Direct Metal Laser Sintering is not as easy as just breaking off the plastic supports. [3]

Our EOS M280, M290, and M400 x 4 production Direct Metal Laser Melting machines use 20 to 60 micron powders and 400W lasers to fuse micro-layers of fine metal together at specific points. [1]

GPI Prototype and Manufacturing Services has been providing Direct Metal Laser Sintering (DMLS), also known as Direct Metal Laser Melting (DMLM) services since 2008. [8] Direct Metal Laser Sintering (DMLS) is an additive manufacturing process. [9] At left, above, are medical parts produced using direct metal laser sintering. [10] Direct metal laser sintering (DMLS) is one of the best known names for laser sintering. [11]

The Direct Metal Laser Sintering (DMLS) machine supports automation and custom configuration with a variety of options. [12] Among these technologies, selective laser sintering (SLS) and direct metal laser sintering (DMLS) can cut costs through accelerated production; reduced tooling costs and work in process; less waste; and parts that remain strong despite being lightweight. [13] The aim of the present study was to record the metal-ceramic bond strength of a feldspathic dental porcelain and a Co-Cr alloy, using the Direct Metal Laser Sintering technique (DMLS) for the fabrication of metal substrates. [14]

Similar to Laser Sintering, a high-powered laser selectively binds together particles on the powder bed while the machine distributes even layers of metallic powder. [15] Khaing MW, Fuh JYH, Lu L. Direct metal laser sintering for rapid tooling: processing and characterisation of EOS parts. [14] Founded in 1989, they are a pioneer and world leader in the field of Direct Metal Laser sintering (DMLS) and provider of highly productive Additive Manufacturing Systems for plastic materials. [16] Sodick's OPM250L combines direct metal laser sintering (DMLS) with high-speed milling and is primarily designed for moldmakers. [17] SLM is very similar to Direct Metal Laser Sintering and according to rumours the name difference is due a falling out between the parties developing the method and varying patents. [18]

Powder Bed Fusion is a popular technique for metal additive manufacturing and includes two main technologies: Laser Sintering and Electron Beam. [11] Currently at our Lake Bluff, Illinois manufacturing facility we are running six metal additive manufacturing machines from EOS. Our metal laser melting systems include two EOS M270, two EOS M280, and two EOS M290. [8] A high-quality laser sintering machine can cost well over $1 million, and that does not cover maintenance and post-processing of parts. [11]

With the EOS M400 x 4., quad laser DMLS/ DMLM machine, speed and cost efficiencies are also now a reality in Metal AM. i3D MFG utilizes its EOS M400 x 4 to run production parts for a variety of industry projects. [1] As with Selective Laser Sintering, parts are surrounded with the material powder in the build chamber. [3] This is also similar to Selective Laser Sintering in that powders are used along with a laser to create parts layer-by-layer. [3]

Simchi A. Direct laser sintering of metal powders: Mechanism, kinetics and microstructural features. [14] Although the predominant fabricating technique of dental metal-ceramic substrates is the casting technique, over the recent years the evolution of digital technology has developed new techniques of construction, such as Stereolithography (SLA), Fused Deposition Modeling (FDM) and Selective Laser Sintering (SLS) 10, 11 as well as Hot pressed technique. 12 The SLS technique is applied mainly to metals, but can also be applied to polymers and ceramics. [14] By material, the selective laser sintering equipment market has been segmented into metal and nylon. [13]

Some SLS machines use single-component powder, such as direct metal laser sintering. [19] After the accuracy was checked and verified, the custom-made subperiosteal implant was sent to a powerful direct metal laser sintering (DMLS) machine (ProX-DMP100, 3D Systems, Rock Hill, SC, USA) for fabrication. [20]

The company now offers Direct Metal Laser Sintering (DMLS), a direct metal laser melting (DMLM) or laser powder bed fusion (LPBF) technology that the company says can accurately create parts with complex geometries that conventional manufacturing methods, such as CNC machining, cannot. [21] Direct Metal Laser Sintering (DMLS) is a manufacturing technology that uses a fiber optic laser to fuse together layers of metal powder. [22] This metal additive part is an all-in-one tessellation created using Direct Metal Laser Sintering (DMLS). [22] In the last few years, however, direct metal laser sintering (DMLS) technology has been introduced in the dental field. [20] The new direct metal laser sintering (DMLS) techniques available today provide the ability to fabricate custom-made grids or even implants that perfectly adapt to the specific anatomical requirements of patients. [20] Inclusion criteria were patients over the age of 60, treated with custom-made direct metal laser sintering (DMLS) titanium subperiosteal implants (Eagle-Grid, BTK, Dueville, Vicenza) during a two-year period (2014-2015) and restored with fixed restorations; all enrolled patients needed to have complete pre- and postoperative clinical and radiographic documentation, with at least 2 years of follow-up. [20] It is similar to direct metal laser sintering (DMLS); the two are instantiations of the same concept but differ in technical details. [19] This resin model was only produced to test the accuracy and fit of the subperiosteal implant after fabrication via direct metal laser sintering (DMLS). [20] Additive Manufacturing of metals originated in the early 1990's through a process known as direct metal laser sintering. [23] Jeff Schipper, director of special operations at rapid prototyping company Proto Labs, has attributed the rise of processes like direct metal laser sintering to their ability to compete directly with traditional processes like CNC machining and casting both in terms of quality of the end product but also in emerging applications such as lightweighting. [21]

The Matsuura LUMEX metal laser sintering hybrid milling machine is capable of quick turn production of custom parts and molds, whether prototypes or small production run parts and molds. [24]

Additive manufacturing services provider Addaero Manufacturing (New Britain, CT) has invested in direct-metal laser sintering (DMLS) technology, adding two EOS M 290 machines from EOS (Krailling, Germany). [25] Laser sintering enables the production of deep features by building them one layer at a time, eliminating the need to machine these features with EDM. [17]

St. Paul, MN (March 27, 2018) Matsuura Machinery USA, Inc. announces the planned exhibition of the Matsuura LUMEX Avance-25 Metal Laser Sintering Hybrid Milling Machine at AMERIMOLD 2018, the annual tradeshow for the business development, best practices and networking interests of the plastic injection mold manufacturing industry. [24] The Matsuura LUMEX Avance-25 metal laser sintering hybrid milling machine is a powder bed metal AM platform with subtractive machining capability. [24]

[20] The Matsuura LUMEX Avance-25 relies on one-machine, one-process manufacturing of complex molds and parts by fusing metal laser sintering (3D SLS) technology with high speed milling technology. [24]

Selective Laser Sintering (SLS) is an additive manufacturing process. [9] Use the chart below to explore the different material options available for use during the Selective Laser Sintering process. [26]

Direct Metal Laser Sintering (DMLS) uses electrically powered machine. [27] It also uses different technology like SL for thermoplastic-like parts and SLS for industrial grade nylon components and direct metal laser sintering (DMLS) for a fully dense metal production. [28] Direct metal laser sintering (DMLS) is an emerging additive manufacturing technology that has great potential to change the way metal parts are manufactured. [27] Direct metal laser sintering (DMLS) is an additive manufacturing technique that uses a laser as the power source to sinter powdered material (typically metal), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure. [29] Direct Metal Laser Sintering (DMLS): Laser beams melt and bind materials, opening up a huge range of possibilities for lightweight, super-strong construction without conventional joints or bindings. [30] Familiar laser-based systems are known as Selective Laser Melting (SLM), Direct Metal Laser Sintering (DMLS) or Direct Metal Laser Melting ( DMLM ). [31] The acquisition increases their AM capacity and capability, making it the largest direct metal laser sintering (DMLS) AM manufacturer in Canada with ISO 13485:2016 Quality Management System certification.

[20]

The laser sintering machine then produces the models on a moveable platform by applying incremental layers of the pattern metallic material. [20] Selective laser sintering (SLS) was developed and patented by Dr. Carl Deckard and academic adviser, Dr. Joe Beaman at the University of Texas at Austin in the mid-1980s, under sponsorship of DARPA. 4 Deckard and Beaman were involved in the resulting start up company DTM, established to design and build the SLS machines. [19]

The selective laser sintering (SLS) equipment market was valued at USD 274.3 million in 2017 and is projected to reach USD 947.4 million by 2023, for both equipment and material, growing at a CAGR of 22.8% during the forecast period, whereas the market for equipment, inclusive of SLS and DMLS, is projected to grow at a CAGR of 27.5% during the forecast period. [13] The OPM250L alternates between milling and laser sintering, which reduces the number of parts necessary to build a mold. [17] Bae EJ, Kim JH, Kim WC, Kim HY. Bond and fracture strength of metal-ceramic restorations formed by selective laser sintering. [14] Bae EJ, Kim HY, Kim WC, Kim JH. In vitro evaluation of the bond strength between various ceramics and cobalt-chromium alloy fabricated by selective laser sintering. [14] The overall selective laser sintering (SLS) equipment market is projected to witness significant growth during the forecast period. [13] Laser sintering is useful as well for making sintering density changes in molding applications that require the placement of porous structures to facilitate gas venting. [17]

It falls to additive contract manufactures to establish material consistency across their machine fleet to promote the repeatability and control of the Direct Metal Laser Melting (DMLM) process. [27] DMLM metal machines from Concept Laser use lasers to melt layers of fine metal powder and create complex geometries with incredible precision directly from a CAD file. [33] The use of the term, "sintering" is a generic description of the process that most Metal AM machines use. [24]

For polymers, it is concentrating on direct laser sintering and fused deposition modeling while also exploring other processes. [34] Selective laser sintering ( SLS ) is an additive manufacturing (AM) technique that uses a laser as the power source to sinter powdered material (typically nylon / polyamide 1 2 ), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure. [19] F. Mangano, M. Bazzoli, L. Tettamanti et al., "Custom-made, selective laser sintering (SLS) blade implants as a non-conventional solution for the prosthetic rehabilitation of extremely atrophied posterior mandible," Lasers in Medical Science, vol. 28, no. 5, pp. 1241-1247, 2013. [20] The Matsuura LUMEX Avance-25 combines selective laser sintering (SLS) along with high speed milling (HSM) commonly called Hybrid AM. [24]


It sends a highly concentrated metal powder stream through an extruder, which is immediately met with a laser at the surface of the part. [35] A laser beam fuses metal powder as it is slowly released and deposited to form the layers of an object by an industrial robotic arm. [35] One is called Directed energy deposition (DED) or laser metal deposition (LMD). [35]

The parts created with DMLS have mechanical properties equivalent to a cast metal part. [35] This groundbreaking hardware tandem is making metal additive manufacturing much more affordable and capable of producing parts faster. [35] The other deposition technology is called Electron Beam Additive Manufacturing (EBAM), a type of soldering process, where a very powerful electron beam is used to fuse a 3 mm thick titanium wire and the molten metal is shaped into very large metal structures. [35]

Layers are formed by gluing together the metal particles and later sintering (or melting) them together in a high-temperature kiln, just like you would do for ceramics. [35] The Metal X offers a build size of 250 x 220 x 200, and a layer height of 50 microns. [35]

One other possibility, which is also similar to ceramics-based crafts, is to mix the metal powder into a metal paste. [35] Even mixing different materials, like plastics and metals into the same object, will be possible. [35] This metal alloy has a very high specific strength. (That?s strength divided by density, which basically indicates the force required per unit area). [35] Services often turn to other companies that are specialized in metal production to finish the order. [35] While you can?t really fuse metal filament on your desktop, very large industrial metal manufacturers can. [35]

It works in the following way: An energy source (a laser or another energy beam) fuses an "atomized" powder (perfectly round, tiny, spherical particles) to create layers of an object. [35] Essentially a laser selectively melts a 2D design onto a flattened bed of powder before a new layer is pushed on top and the process is repeated. [35]

The 2000 has two lasers and an even larger build volume of 800 x 400 x 500 mm. [35]

Fabrisonic?s production machines are three-axis CNC mills, which have an added welding head for additive manufacturing. [35] Metal binder jetting applies a liquid binding resin onto a powdered metal material. [35]

Using subtractive processes for manufacturing of metal mesh or weight- reduced parts will dramatically increase the manufacturing time and cost due to the amount of material removed. [2] Streamline your manufacturing with precision metal prototypes and low-volume metal production parts that would be impractical or cost prohibitive to machine. [36] These machines are much less costly, relatively easy to use and produce fully dense metal parts suitable for end-use applications. [37]

Manufacturing with DMLS can be advantageous if engineers design parts with complex geometries, such as integrated fastening features, long and narrow channels, custom contours, and metal mesh structures. [2] DMLS materials build fully dense, corrosive resistant and highly robust metal parts that can be further treated through heat, coating and sterilization. [6]

The metal powder needed to actually build something is often proprietary, as are the lasers used to sinter it into useful products. [37] SLS however uses plastic powder materials whereas DMLS uses metals. [3] DMLS parts are commonly used during pre-launch activities for product testing, whereas the final product is made with a tool (i.e. die casting, metal injection molding, sand casting). [2] DMLS parts are stronger and denser than investment casted metal parts, and they can help you get to market first with faster turnaround times. [6] DMLS offers fantastic topology optimization through creating stronger metal parts that weigh less. [3]

Specializing in production parts, i3D MFG is a 3D metal additive manufacturer that stocks a wide variety of common and uncommon metals. [1] Vader Systems uses an electromagnetic field to build parts from liquified metals. [37] When complete, the "green" part is sent through a wash station to remove some of the binder material and then placed in a furnace that burns away the remaining binder and fuses the metal particles together. [37] It creates fully functional parts out of metals such as Cobalt Chrome, Stainless Steel, Titanium, Inconel, and many others. [2] The main metal powders used include aluminum and titanium, though others such as Cobalt-chrome, Stainless steel and Inconel are also commonly used. [3]

DMLS: Does not melt powder but instead heats the metal powder to a point where it fuses together on a molecular level. [3] With DMLS, the metal supports need to be broken off with machines, which can lead to problems with surface finish on these areas. [3] DMLS is a form of metal powder bed fusion technology, in a similar vein to Electron Beam Melting. [3]

DMLS/DMLM parts are known for strength, hardness, and durability that is comparable to cast or forged parts in a similar metal. [1] It is an optimal metal for parts with thin walls and complex geometries. [1] This continues, layer-by-layer, until the finished metal part is created. [3] Supports help with metal part quality in a variety of ways. [3]

With a more inviting price point than other 3D technologies, 3D additive metal extrusion manufacturing has the potential to transform metalworking. [37] This process involves metals such as gold, platinum, or silver to create stunning pieces of jewelry with complex geometries that other manufacturing processes just cannot do. [3]

We create metal parts using a fiber laser fired onto a metal plate, repeatedly adding layers of powdered metal and fusing them to previous layers. [36] DMLS uses a precise, high-wattage laser to micro-weld powdered metals and alloys to form fully functional metal components from your CAD model. [6]

Once the laser has finished sintering the full layer, a new layer of powder is spread again by the roller, and the process repeats. [3] The process is comparable to welding with a very fine and precise laser. [5]

Recently, GE Additive have made their move to take over the industry, purchasing companies such as Concept Laser and Arcam. [3]

DMLS metals offer similar properties that industries such as aerospace, medical, and energy heavily rely on for efficient production. [5] Our state-of-the-art tools and valuable partnerships enable us to create custom metal powders and corresponding computer programs, or parameter sets, to provide our clients with the exact product they need. [1] Metal powders are extremely expensive, with stainless steel 316L powders costing $350-450/kg. [3] Geometry of metal powder (finer powders vs less fine powders). [3]

Build tough and hardworking metal prototypes to test components in real-world applications. [6] Metal Additive Manufacturing is more than proof of concept or prototype. [1] Since the metals are the same as those used with MIM, aerospace and medical oversight approvals are much easier to attain. [37]

The technology works by extruding rod-like cylinders of powdered metal previously blended with a plastic binder through a nozzle to create part layers 50 ?m (0.002 in.) thick. [37]

Granted, such a machine will deliver only hobby-grade accuracy, but it does give the user valuable experience with processing additively manufactured parts. [37] High complexity - Difficult to machine parts, custom medical pieces, hollowed or lightweight parts, and artistic pieces fall in this category. [2]

Hanson, who is the proprietor of KAHMCO LLC, has more than 35 years experience in manufacturing, machine tools, fabrication and ERP systems. [37] At Stratasys Direct, our services are backed by more than the largest fleet of machines in North America; we have nearly thirty years in the industry and a team of engineers ready to assist with every step of your project. [6] AM machine builder ExOne, for example, offers a variety of binder-jetting machines and materials ranging from bronze to tungsten. [37] You can figure on $500,000 and up for a laser-based powder bed machine, plus the software, training and ancillary equipment to support it. [37]

There?s no need for argon or nitrogen gases as there is with laser-based systems, nor are there any concerns over a laser beam sparking an explosion in an aluminum or titanium dust-filled atmosphere. [37] With a price tag hovering around $100,000 for a complete system, manufacturing costs are reportedly up to 10 times less than alternative metal-additive technologies and up to 100 times less than machining. [37] Unlike the startup cost (which is applied to most materials), this cost vanishes when the price is higher than the minimum price. [15]

Simply upload your STL file and after your quotes are generated you can filter by process, lead time, price, finish, and color. [4] With a more inviting price point than other 3D technologies, it has the potential to shake things up. [37]

The two technologies have a lot of similarities: both use a laser to scan and selectively fuse (or melt) the metal powder particles, bonding them together and building a part layer-by-layer. [38] It uses a laser to fuse aluminum, cobalt chrome, stainless steel, titanium, and other powdered alloys into fully dense metal parts, "drawing" them layer by layer from the bottom up. [10] These techniques are grouped together since they each begin with a layer of metal powder being rolled onto the build tray, and then an energy source (laser or electron beam) fuses or melts the powder into deliberate 2D designs. [11] Automotive OEMs, aircraft manufacturers and designers all recognise the potential of the manufacturing technology, which enables wafer-thin layers of metal powder to be bonded into components by radiation energy from lasers,. [39] SLS technology uses a laser to harden and bond small grains of plastic, ceramic, glass, metal, or other materials into layers in a 3D structure. [26] A thin layer of metal powder is spread over the build platform and a high power laser scans the cross-section of the component, melting (or fusing) the metal particles together and creating the next layer. [38] Electron beams produce more energy than lasers and are chosen to fuse the highest temperature metal superalloys for parts used in extreme conditions such as jet engines and gas turbines. [11]

GPI currently has 6 DMLS machines from EOS to build metal prototypes and for metal additive manufacturing of complex end-use parts. [8] Movement of the part occurs from the act of spreading a new layer of powder over the previously sintered layer or larger cross sections of the metal part warping during the sintering process. [40] When the build process is finished, the parts are fully encapsulated in the metal powder. [38] The differences between SLM and DMLS come down to the fundamentals of the particle bonding process (and also patents): SLM uses metal powders with a single melting temperature and fully melts the particles, while in DMLS the powder is composed of materials with variable melting points that fuse on a molecular level at elevated temperatures. [38] Using subtractive processes for manufacturing of metal mesh or weight reduced parts will dramatically increase the manufacturing time and cost due to the amount of material removed. [40] The practical advantage is that very few other metal additive manufacturing techniques can produce fully dense parts with properties approaching wrought material. [11] There are other additive manufacturing processes that can be used to produce dense metal parts, such as Electron Beam Melting (EBM) and Ultrasonic Additive Manufacturing (UAM). [38] SLM and DMLS can produce parts from a large range of metals and metal alloys including aluminum, stainless steel, titanium, cobalt chrome and inconel. [38] DMLS creates fully functional parts out of metals such as Cobalt Chrome, Aluminum, Stainless Steel, Tool Steel, Titanium, Inconel, and many others. [40]

Metal SLM and DMLS parts have almost isotropic mechanical and thermal properties. [38]

Escape holes Holes are required on hollowed metal parts to remove unmelted powder. [40] When the scanning process is complete, the build platform moves downwards by one layer thickness and the recoater spreads another thin layer of metal powder. [38] In that case, additive direct processing of metal powders may actually take a significantly higher share of the foundry?s market, especially for small and medium-sized components. [39]

Unlike other laser and powder based additive technologies, DMLS parts move around in the build envelope if not properly secured to the build platform. [40] It uses a laser to fuse tiny bits of nylon powder, tracing the geometry of digitally sliced CAD models layer by layer and working from the bottom of the part upwards. [10] Using lasers is also considered to be a degrading process since the last part you create in a manufacturing run typically differs from the first, if the laser hasn?t been carefully watched and re-calibrated along the way. [11] There are a number of reasons for the popularity of PBF, most notably that the high-precision lasers and electron beams can create intricate parts using a wide range of materials. [11]

SLS technology uses a laser to harden and bond small grains of nylon and elastomer materials into layers in a 3D dimensional structure. [26] After the first layer is sintered, the build platform lowers, another powder layer is spread, and the laser sinters the second layer. [9] The result is a part nearly as dense as one that has been laser fused but without the accompanying thermal effects (or need for build supports), and suitable for most end-use applications. [10]

During the DMLS process the laser creates a melt pool that is slightly wider than the laser diameter from heat dissipating into the surrounding powder. [40]

The metal powder in SLM and DMLS is highly recyclable : typically less than 5% is wasted. [38] This post is part 3 of a guide by 3DEO meant to introduce engineers and designers to metal additive manufacturing. [11] With 18 employees dedicated to DMLS/DMLM, GPI produces metal prototypes and end-use parts with complex geometries not possible with traditional machining. [8]

Plus, it took many years for the metals used with DMLS to pass muster for use in aircraft and human bodies. [10] The materials used in both processes are metals that come in a granular form. [38] The build chamber is first filled with inert gas (for example argon) to minimize the oxidation of the metal powder and then it is heated to the optimal build temperature. [38] A blade spreads the metal powder creating a uniform thickness over a build platform. [9] In many applications, such as aerospace components, it is now possible to build almost any size and quantity economically using Binder Jetting in combination with metal casting: For example, pumps, drive wheels, exhaust manifolds, housings, frames, large structural components etc. are already being produced using rapid casting. [39] The rare production scenarios where the costs can be justified include high-end applications such as aerospace and turbine components, but they are not practical for more mainstream metal applications. [11] EOS partnered with Integrated 3D Manufacturing (i3D) to greatly expand their metal additive manufacturing (AM) production capabilities with the acquisition of an EOS M 400-4. [41] If you would like to hear more about our previous metal additive manufacturing projects, please contact one of our sales reps to schedule a meeting. [8] PBF is a currently the most common and well known form of metal additive manufacturing. [11]

Metal casting is thus a proven manufacturing method that already provides a high level of customer satisfaction, because components of almost any size can be economically manufactured as one component. [39] Regardless of platform, the process is similar in capability and product integrity to the decades-old metal injection molding (MIM) process. [10] This fuses the individual metal particles one to another in a manner similar to metal injection molding (MIM). [10]

Because DM leverages the same well-understood metals used with MIM, the certification road should be much shorter, but it must be traveled nonetheless. [10] We offer a variety of metals including aluminum, stainless steel, titanium, inconel and cobalt chrome. [8] Precious metals, such as gold, platinum, palladium, and silver can also be processed, but their applications are fringe and mainly limited to jewelry making. [38]

At center, a part made using Desktop Metal (Photo courtesy: Desktop Metal), which uses a process similar in capability and product integrity to metal injection molding (MIM). [10] This additive process allows metal parts to be grown out of a bed of powdered metal. [8]

EXAMPLE #4: The price of DMLS parts is heavily influenced by build time and the amount of material being used. [40] A part with reduced mass allows for a lower price because it takes less time to build, uses less material, and has a higher success rate of being produced correctly the first time. [40]

The volume of a part is decreased, either by redesign or by using another manufacturing process to create the geometry, the overall part price will go down significantly. [40] The quoted price of parts is heavily influenced by factors such as support structure design and removal of support. [40] The surface area to volume ratio of a part plays a large role in determining the quoted price of a given part. [40]

Prior to being sent to the DMLS machine, part support structures are designed and built. [40] The high machine cost is amortized with each build, and passed through to each part created. [11] Movement of the part during the build will cause failures in part accuracy and could potentially lead to machine crashes. [40] SLS machines from 3D Systems offer the industry?s best finishes, leaving you with high-quality parts that are perfect for rapid prototyping, master patterns, end-use production, machine tools and more. [26] For most applications, machine amortization alone for PBF causes part cost to be prohibitively expensive. [11] High complexity - Difficult to machine parts, custom medical pieces, hollowed or lightweight parts, and artistic piece fall in this category. [40]

In SLM and DMLS almost all process parameters are set by the machine manufacturer. [38] Preparation of the design before being sent to the DMLS machine and the post processing afterwards can be time consuming. [40]

In ball milling, a machine is used to grind and blend materials via high impact. [26] FDM machines offer a greater number of material options than SLS and MJF combined. [10]

The laser goes to work rendering the first 2D layer, sintering it into a solid form. [9] The laser traces the pattern of each cross section of the 3D design onto a bed of powder. [26] Skin and cores are processed using different laser power and scan speed, resulting in different material properties. [38] Laser cutting in India, which is done through emission of radiation, has gained popularity due to its simplified process. [42] To make your work easy, you can hire laser cutting services. [42] Many laser cutting services in Pune are providing superior work to their clients. [42]

You can connect with 3D Spectra technologies for laser cutting in Pune. [42]

Chances are good that if a metal part is easily and cost-effectively made on a CNC lathe or milling center, it?s probably not a good candidate for DMLS or Desktop Metal. [10] Part designers must take all this and more into consideration before jumping onto the Desktop Metal bandwagon. [10]

Powdered metal is spread across the entire build platform and selectively melted to previous layers. [8] The studio system uses a process analogous to that of FDM, heating and then extruding rods made of powdered metal mixed with a polymer binder. [10]

The PBF process is quite complex, which results in very expensive machines. [11] The sheer number of companies making PBF machines is also beneficial because the technology is widely available for the companies willing to invest in these systems. [11] Earlier, the work which was done manually has now been done through machines. [42]

With services connected in over 140 countries, we'll find the fastest and most price competitive manufacturing service near you. [38] As a direct comparison, the price of pure cast steel is around 6.50 to 32 Euro per kilogram. [39]

Ten metal substrates were fabricated with powder of a dental Co-Cr alloy using DMLS technique (test group) in dimensions according to ISO 9693. [14] The metal-ceramic bond strength of the specimens, in which the metal substrates were fabricated using the DMLS technique, cover the lower acceptable limit of 25 MPa, in accordance to ISO 9693 while no statistically significant difference in the metal-ceramic bond strength was recorded between specimens produced by cast and DMLS applied techniques. [14] Three of the thirteen metal substrates from each group were used to determine the E and the other ten to record the metal-ceramic bond strength, using a universal testing machine (Tensometer10, Monsanto, Akron, OH, USA). [14] Although the advantages of the DMLS technique are obvious in the construction of the metal substrate of dental metal-ceramic restorations, the knowledge concerning their bond strength is limited, so the present study aspires to contribute in this direction. [14] Superficial roughness of the metal substrates due to different porosity between the two applied techniques may play role in the overall metal-ceramic bond strength. [14]

Additive manufacturing system for the industrial production of high-quality metal parts. [16] "A 10 times greater ease of use is going to blow the doors off the market because, when you engineer a part, the question is: how quickly can you get that part in your hands from plastic composites to metal? We already have the plastic composites nailed. [43]

There are various classifications for SLS technologies, either according to the binding mechanism (Solid State Sintering, Chemically Induced Binding, Liquid Phase Sintering, Full Melting) or the sintered materials (polymers, metals, ceramics or compo-sites). [14] The Metal X flanked by the Sinter-1 sintering oven on the left and Wash-1 washing station on the right. (Image courtesy of Markforged.) [43]

These methods include 'Laser engineered net shaping', 'directed light fabrication', 'direct metal deposition' and '3D laser cladding'. [18] The laser's beam selectively melts the metal particles in the shape of the object, and the molten metal solidifies to form the item one thin layer at a time. [44]

The technology works on iron, cobalt-based, nickel-based alloys, tungsten carbide and other metal powder coated metal. [18] SLM sinters powders making it useful for alloys as opposed to SLS which processes single element metals and certain alloys. [18] Co-Cr powder was used for the fabrication of metal substrates (EOS-Cobalt-Chrome SP2, EOS, Munich, Germany). [14] Two studies 9, 26 examined the mode of failure in the fractured specimens using EDS. Xiang et al., 26 recorded increased ceramic elements on the metal substrates in both applied techniques, but ceramic amounts were higher when the SLM technique was used, which led to cohesive mode of failure. [14] In opposite, the metal substrates constructed by DMLS technique showed little or no microporosity, as it is shown in SEM micrographs ( Fig. 2, Fig. 3 ). [14] Within the limitations of the present in vitro study, the authors can conclude that the metal substrates constructed by the DMLS technique showed little or no micro-porosity compared to the cast technique. [14] SEI/SEM micrograph of DMLS metal substrate presenting non-to minimum micro-porosity. [14] DMLS and other metal powder bed fusion technologies are notoriously complex, often leading to repeatability and quality issues. [43] Farsoon Technologies signed an agreement with Oerlikon to supply qualified Oerlikon AM metal powders for Farsoon additive manufacturing metal systems. [13] We're depositing plastic that's got metal powder bound into it. [43]

Renishaw signed a partnership agreement with FalconTech Co., Ltd. (China) for extending the distribution of its solutions based on metal additive technology in China. [13] Because the material drawer slides out, you can quickly change the metal feedstock from cobalt-chrome to stainless steel to titanium and back again, enhancing the M 100's flexibility. [44] UPM is a relatively new method that can operate with metals but also a variety of other materials. [18]

Nowadays, base metal alloys (Co-Cr and Ni-Cr) are mainly used for the fabrication of fixed metal-ceramic restorations. [14] It was originally used by NASA to build metal objects in space. [18] SLS, while mostly used for plastics, can also be used for certain types of metals. [18] Here are some of the most common types used to digitally craft metal objects. [18] Nitrides, metals and composites have been used for this method. [18]

As it must be created in a lab, it is a good case study for just what kind of mass production of metals additive manufacturing can accomplish. [45] The Metal X system could open up the possibility of batch production. [43] Mark tentatively shows clients other metals currently in beta testing, but without the promise that they are ready for production in the same way that stainless steel is. [43]

For this reason, Markforged is not overpromising the metals that will work with the ADAM process. [43] They're just not as stable and repeatable as a thermal process for metal. [43]

Another thirteen metal substrates were produced by this technique. [14] Twenty metal substrates were constructed in dimensions according to specification ISO 9693 and were equally divided into two groups. [14] The upper line represents the metal substrates of the control group, while the low line represents the metal substrates of the test group. [14] The increased amounts of Ce represents residues of bonding agent on the metal substrate, while the increased amounts of Si represents residues of feldspathic porcelain ( Fig. 6, Fig. 7 ).

Renishaw introduced its RenAM 500Q four-laser metal AM system which it says can significantly improve productivity with a build rate ranging to 150 cubic centimeters per hour. [17] Additive Industries will share its metrics for productivity growth in metal additive manufacturing at the 2018 Additive Manufacturing Conference. [12] This could lead to better conductors, tensile strength, and other attributes of laboratory metals than "mined-and-refined" metals such as steel and copper. [45] Metal is the last piece you need to fill in the design space," Mark said. [43] Refractory metals and high-performance polymers are expected to become available within the next few years and to enable new applications. [17] As a result it can work with such a diverse range of metals. [18]

For instance, OR Laser, a German laser systems manufacturer, debuted the Orlas Creator hybrid, an SLM machine with the added benefit of three-axis milling to create net parts. [17] To add material via selective laser melting (SLM) or other AM processes, the part is placed into the AM machine and usually loses all of its reference points. [17]

"When you perform DMLS, the laser is welding every layer and you're getting all of the locked-in thermal stresses that are stored in the part as you're building it," Mark said." [43] With its ability to make small metallic parts, the EOS M 100 uses a powerful laser to create durable parts accurately and reliably. [44] Through a combination of laser powder-bed fusion, design and optimization technology, Betatype reduced the cost of an automotive part from more than $40 to less than $4. [12] One of the substrates that was produced by the previously referred casting technique, was scanned by Computer Aided Design technology (CAD) and the data were sent to the special DMLS device, operating in 161.5-191.5 Jmm−3 laser energy conditions (EOS M270, EOS, Munich, Germany). [14] The technology deposits powders and uses lasers to heat them into shape onto a platform. [18] In parallel mode, the machine makes optimal use of the laser unit by targeting multiple locations concurrently. [17] The machine combines the build platform of the original Creator, an SLM machine that OR Laser launched at Formnext 2016, with a 250-Watt laser and processing speeds of 3,500 millimeters per second. [17]

Swiss grinding machine manufacturer Studer leverages additive manufacturing technology to build parts such as hydraulic components, machine covers and coolant nozzles for its high-precision machines. [12] The result is optimized lubrication during grinding, increased service life of the grinding wheel, and quick and easy parts assembly during machine production. [12] The AM S 290 Tooling machine, which is based on the EOS M 290 DMLS system, is designed to address the mold and die industry's need to produce innovative mold inserts using AM. GF Machining Solutions and EOS aim to integrate AM machines into the production process of mold inserts, including the necessary software and automation link with downstream machine tools and measuring devices. [17]

While an increase in size might typically mean a decrease in quality, these systems also feature higher-end parts, such as high-resolution encoding, that actually makes the machines twice as stiff and flat as the lower-end products, according to Mark. [43] That means a huge increase in the materials those machines use. [45] In addition to displaying what the machine is currently doing and its raw material supply level, any faults are indicated. [44]

Matsuura showcased its latest hybrid machine, the Lumex Avance 60, which opens this technology to bigger applications in new industries, such as aerospace and automotive, accommodating a maximum workpiece size of 600 by 600 by 500 millimeters and a maximum weight of 1,300 kilograms. [17]

At launch, Desktop Metal announced that it had developed a microwave sintering technology that could quickly and evenly sinter parts. [43] Because you're bulk sintering the entire part at the same time, there isn't this locked-in stress. [43] Each day, 20 parts will be run through the Wash-1 at a time and, at the close of a day, these parts will be placed in the sintering station. [43] The resulting porous, "brown" part is subsequently placed in a sintering furnace (Markforged has its own furnaces, the Sinter-1 and Sinter-2). [43]

Takaichi et al., 13 observed dense sintering when the laser power was over the 400 Jmm −3, while internal porous structure observed when laser power was lower than 150 Jmm −3. [14] LENS lasers can range from 500W to 4kW. The process has been used to process titanium, stainless steel and Inconel. [18] The report covers the SLS equipment market segmented by laser type, material, application, industry, and geography. [13] It uses a powerful laser and steerable mirrors to precisely trace the item under construction out of a bed of powdered raw material. [44] A material or wire is heated with a laser on top of an existing object, soldering them together when using any DED method. [18]

Both methods make use of lasers to arrange a wide spectrum of alloys. [18] GE Additive (parent company of Concept Laser) established Customer Experience Center in Munich, Germany. [13] At 200 watts, the ytterbium laser has a focus spot of 40 microns and builds the object in precise 30-micron slices. [44] The company says that this enables the lasers to operate simultaneously at any point in the system's build chamber. [17]

These results are in accordance with the results of the present study where 161.5 – 191.5 Jmm −3 laser power had been used. [14] Key to the X series is the integration of a laser that performs a variety of tasks, including laser leveling, in-process inspection and calibration. [43]

Without requiring tools, EOS systems make direct use of digital CAD data to produce polymer parts of the highest quality. [16] It is useful for strengthening, repair, regeneration or direct manufacturing. [18]

The center of attention with the M 100 is its large color screen that presents a process flow overview of the machine. [44] Two companies that realize moldmakers need solutions, not single machines or technologies, are GF Machining Solutions and EOS, and they have partnered to combine their technologies to benefit the moldmaking sector. [17] EOS online support resources are sparse; however, the company delivers top-notch training to your staff so you can get the most out of the machine. [44]

That said, the M 100 machine is the size of a refrigerator at 31 x 37 x 89 inches and weighs 1,300 pounds. [44]

It has interior illumination, and below the system's control screen, is a window for watching the laser's beam light up the raw material as it traces the shape of the item under construction. [44]

An additive manufacturing layer technology, SLS involves the use of a high power laser (for example, a carbon dioxide laser ) to fuse small particles of plastic, metal, ceramic, or glass powders into a mass that has a desired three-dimensional shape. [19] The Matsuura LUMEX Avance-25 achieves the highest accuracy in part fabrication since metal powders are melted and sintered via laser, while surfaces are precisely milled at high speeds. 3D cooling channels can be incorporated into molds in the single setup, thereby increasing cooling efficiency and enabling high-cycle injection molding with better than ever quality and precision, reducing costs and improving efficiency. [24] "The Matsuura LUMEX Avance-25 achieves the highest accuracy in part fabrication since metal powders are melted and sintered via laser, while surfaces are precisely milled at high speeds," said Tom Houle, Director, LUMEX, NA, Matsuura Machinery USA, Inc. [24]

The process disperses a very fine layer of metal powder allowing for high detail resolution and is fused together using a focused laser beam. [22] The platform then moves down by the preprogrammed layer thickness, a fresh film of metal powder is laid down, and the next layer is melted via exposure to the laser source. [20]

The EBM process melts metal powder with an electron beam to build parts layer by layer. [21] They created a process that ties to the metal injection molding standards MPIF 35 (Metal Powder Industries Federation?s Materials Standards for Metal Injection Molded Parts). [46] The company is also working as part of the American Society for Testing and Materials (ASTM) International on developing parameters and standards for new metal alloy powders for additive manufacturing. [21] This latest technology utilizes a variety of metal and alloy materials to create strong and durable parts from your 3D CAD data without the need of tooling. [22] Unlike other metal injection molding or injection molding processes, Amorphous Alloy parts come out of the mold in a useable state and does not require expensive sintering or binder removal techniques. [22] Because SLS can produce parts made from a wide variety of materials (plastics, glass, ceramics, or metals) citation needed, it is quickly becoming a popular process for creating prototypes, and even final products citation needed. [19] Another significant factor is the swift emergence of a three-year-old company that?s determined to change the way engineering and manufacturing teams produce metal parts. [46] Although laser-based metal additive manufacturing technologies are capable of producing real metal parts out of steel, titanium, and aluminum, the microstructures of those parts are much different from those made by traditional production processes like casting, machining, or stamping. [46] As the parts come off the engineers? desks and are tested, their properties are well understood, making it much easier and less expensive to take those parts into mass production via processes like metal injection molding and hot isostatic pressing (HIP). [46] Stratasys also claims that DMLS parts are stronger and more dense than investment casted metal parts. [21]

Wohlers contrasted that with a laser based additive process by which metal is welded to metal. [46] This process uses laser toolpaths to weld powdered metals into three dimensional parts. [23]

Because finished part density depends on peak laser power, rather than laser duration, a SLS machine typically uses a pulsed laser. [19] That means buying more machines to do more of the same laser welding techniques that produce those properties in a part. [46] "If you?ve got a machine that builds at a couple of cubic inches per hour, like a laser based system does, then you need more machines to build those parts," he continued. [46] Featuring some of the most advanced additive technologies available, machines from Arcam EBM and Concept Laser enable customers to grow products quickly and precisely. [33]

Several different machine envelope sizes -- including the largest powder-bed metal additive system in the world -- are available to meet the needs of any industry. [33] "They?re selling in higher volumes than most companies that first offer, say, a metal powder bed fusion machine, because those machines are typically much higher priced and require a big commitment to make them work well." [46] Matsuura Machinery USA, Inc. delivers unmatched excellence in 5-axis, vertical, horizontal, linear motor, multi-tasking CNC machine tools and machines with a powder bed metal AM platform with machining capability. [24]

According to 3DEO, the Intelligent Layering process begins by spreading a thin layer of metal powder over the build area. [46] Millions are jetted per second, binding metal powder to form high resolution layers. [46]

At the end, when our parts come out, they?re just like MIM parts, but we created them without all the tooling costs required to create a metal injection mold. [46] Finished parts resemble MIM parts, but are created without the cost of creating a metal injection mold. [46]

"Increasingly, global manufacturers are becoming aware of the benefits of producing metal parts by additive manufacturing," said Wohlers Associates in a release announcing its report. [46] These amorphous metal parts were created with patented Lquidmetal® technology. [22] "Let them design parts, work in their office space, and let?s remove the barrier to entry for them to actually start playing around with metals. [46] "Desktop Metal is really rethinking the way that parts might be made," said Wohlers. [46] If you can feel the power of Desktop Metal?s claim that it?s reinventing how metal parts are manufactured, you?re not alone. [46] A finished metal part produced on Desktop Metal?s Studio System. [46] The Studio System is a three-part solution aimed at allowing engineers to rapid prototype metal parts without the need for outsourcing. [21]

Amorphous Alloy Injection Molding, also known as amorphous metal casting, is capable of manufacturing complex geometries in large quantities using multi-cavitation tooling. [22] "The way we think about our process is "MIM (metal injection molding) without the molds,?" said Lance Kallman, 3DEO?s vice president of business development, in an interview at Singularity University?s Exponential Manufacturing Summit in Boston. [46]

Six materials will be available at launch, such as 316 L, Inconel 625 and Copper but the technology will have ultimately access to a wide range of metals from the MIM industry (over 200 materials compatible), including aluminum, super alloys, and titanium. [23] Markforged also currently offers a metals beta test program to its customers that extends the Metal X's material options to include tool steel (A-2, D-2, M-2), aluminum (6061, 7075), and titanium (6AL 4V). [21]

While effective, the technology has major barriers to entry due to the volatile nature of metal powders. [23] "The founders actually created the technology with low cost in mind because there?s obviously a very high end market for metal additive right now. [46] We believe the benefit of this technology covered by the patents will enable substantially increased adoption of metal additive manufacturing." [46] Terry Wohlers also believes the technology has the potential to help the metal additive manufacturing industry. [46] Matsuura?s cutting-edge technology is transformative in today?s world of 3D Metal Additive Manufacturing. [24] In the world of metal additive manufacturing, cost is, by far, the number one barrier to entry. [46] Rather than outsourcing or subcontracting work to additive manufacturing suppliers, Sintavia has taken pains to develop and nurture what amounts to a complete 3D metal manufacturing supply chain--mainly for the aerospace and defense industry-- within its own facility. [46] Sintavia, a metal additive manufacturing supplier in Davie, Florida, has centered its business model on growing an ecosystem of additive manufacturing expertise inside the walls of its vertically integrated manufacturing facility. [46] Our multidimensional services allow us to provide unique answers for you in ways that are otherwise impossible with- out additive manufacturing, metal casting, or machining. [22] The report, published by the consulting firm Wohlers Associates, estimated that 1,768 metal additive manufacturing systems were sold worldwide in 2017, representing a nearly 80 percent increase over 2016, when 983 systems were sold. [46]

That?s because as the metal powder melts, it goes from a solid to a liquid, and then solidifies back into a solid. [46]

The DMLS process created a porous, chemically pure implant from 3D CAD data by melting fine titanium powders with a laser beam (50/W fibre laser with a wavelength of 1070 nm), layer by layer (with layer sizes ranging from 10 to 20 ? m). [20] The laser selectively fuses powdered material by scanning cross-sections generated from a 3-D digital description of the part (for example from a CAD file or scan data) on the surface of a powder bed. [19]

Since the machine's chamber is always filled with powder material the fabrication of multiple parts has a far lower impact on the overall difficulty and price of the design because through a technique known as ' Nesting ' multiple parts can be positioned to fit within the boundaries of the machine. [19] Sand cites three main contributors to the low part cost--extremely low machine cost, the use of off-the-shelf commodity materials, and creative software design. [46]

The machine enables production of complicated parts and molds through total manufacturing by digital engineering, using 3D data. [24] We?re building the parts layer by layer, so we get all the advantages and complexities of additive manufacturing, while at the same time, drastically reducing the machine costs." [46] This technology provides excellent stability and repeatability, which allows the machine to know where in the coordinate system the build is taking place and maintain the overall accuracy of the completed part. [24] The Hybrid technology creates a "finished" part with machined surface finish and accuracy, without inducing the additional variation caused by multiple machine set-ups and part handling. [24] The cost of the machine is just the beginning of a long, costly journey to being able to produce parts in volume, to the specifications required. [46] Each of 3DEO?s machines uses dozens of sensors and cameras that collect operations data as parts are built. [46] Our parts are manufactured on well-maintained, high accuracy machines in our temperature controlled Denver, Colorado facility. [22] They might have hundreds, or even more than a thousand, million-dollar machines in a factory producing aerospace parts. [46] "Although we?re not there yet, machine learning will play a big part in what we?re doing and how we continue to make the factory more efficient." [46]

Most SLS machines use two-component powders, typically either coated powder or a powder mixture. [19] The CNC machine that we use is very low power, which means very low cost because all it?s doing is cutting powder and glue; it?s not cutting a finished molded part." [46]

Find information on the different materials that can be used with GE Additive's additive manufacturing machines. [33] "You can get by with one to three machines for qualifying the materials and processes, and then certifying designs, but you need a lot more capacity for production--and, in some cases, dramatically more," said Wohlers. [46]

"It is a significant investment, and the million dollar machine is just the start," said Matt Sand, president and co-founder of 3DEO, a technology and manufacturing company in Gardena, California. [46] A lot of manufacturing companies--and there?s nothing wrong with this at all--will just buy off-the-shelf machines to be able to produce. [46]

In any case, even without considering the inherent properties of the surfaces of implants fabricated by direct laser manufacturing, the advantages deriving from the application of our new technique for the fabrication of custom-made subperiosteal implants are relevant. [20] Excellent histological and histomorphometric findings have been reported in the scientific literature for implants with a direct laser sintered surface. [20]

DMLS uses a high-wattage laser to micro-weld powdered metals and alloys to form fully functional metal components. [21] These include polymers such as nylon (neat, glass-filled, or with other fillers) or polystyrene, metals including steel, titanium, alloy mixtures, and composites and green sand citation needed. [19] EBAM works by placing metal wire feedstock into a vacuum and heating it with an electron beam. [21] The ability to achieve geometry tolerances as tight as 25 microns is largely due to the limited shrinkage, roughly 0.2% compared to 0.6% in die casting and upwards of 25% shrinkage in MIM (metal injection molding). [22]

Customers often come to Desktop Metal with parts that weren?t designed for additive manufacturing, but instead were designed to be stamped, cast, or manufactured via a more traditional process. [46] Desktop Metal began shipping the Studio System to early customers--including Google?s Advanced Technology and Products (ATAP) group--in December as part of its Pioneers Program roll-out. [46] By introducing technology to make metal parts with well-established properties, Desktop Metal enables engineers to quickly validate their parts. [46]

Powered by a technology called Single Pass Jetting, the Production System is reported to work up to 100 times faster than laser based additive manufacturing systems. [46] In the time that it takes laser based processes to produce just 12 impellers, Desktop Metal?s Single Pass Jetting technology would have produced more than 500, the company says. [46]

The technology utilized in the Matsuura LUMEX series is more accurately described as Powder Bed Fusion with "selective laser melting." [24]

As SLS requires the use of high-powered lasers it is often too expensive, not to mention possibly too dangerous, to use in the home. [19] Learn more about GE Additive, including information on our history, leadership team, and how we have come together with Arcam and Concept Laser. [33] The laser melts selected areas so that they conform to the previous layer. [20] Similar results were found by in 2009 by Kusek, who published a case report of a patient who was rehabilitated using a simplified surgical protocol involving laser surgery and stereolithography. [20]

Once 3DEO?s Intelligent Layering process is complete, the part goes into a MIM furnace for sintering. [46] In this sintering phase, the part shrinks by roughly 20% and densifies to between 96 and 99.8%. [23] Next, the completed part is put into a high-throughput furnace for sintering. [46] The system also consists of a debinder that prepares green parts for sintering by dissolving primary binder. [21]

DMLS is an additive manufacturing (AM) method for creating patterns using thermal fusing (sintering) of powdered metals. [20] For each layer, the machine lays down a film of powdered metal with a precise thickness (approximately 0.1 mm/0.004 inches). [20] The process requires big machines, complicated systems, and powdered metals that need to be controlled. [46] Look out for a Cimquest special edition with everything you will need to know about running a Desktop Metal machine. [23]

We?ll get to know your needs and priorities to help determine the machines and materials that can accelerate innovation in your business. [33] The speed of the Production System drives total cost down by eliminating the need to buy more machines to increase production. [46] "Essentially, these are factory level machines that cost a million dollars, plus whatever the facility?s modifications are, plus dedicated operators and expenses to run them," Myerberg said. [46]

An SLS machine being used at the Centro Renato Archer in Brazil. [19] The user can remove the work piece from the machine and perform additional operations to the in-process build. [24] "Unlike traditional sinter only machines, where the work piece is built in space, with the Matsuura LUMEX hybrid technology, our work piece is built in relation to a coordinate system. [24] For the Hybrid technology, this machine configuration provides the most benefits and allows the user to capitalize on the unique features that can be created with the Matsuura LUMEX Hybrid. [24] Innovative features, including the patented LaserCUSING technology, set these machines apart. [33] Amerimold is owned and operated by 4th-generation, family-owned Gardner Business Media and is presented by MoldMaking Technology magazine, Plastics Technology magazine and Modern Machine Shop magazine. [24]

Visser Precision is consistently adding capacity in our additive department to maintain machine availability for rush jobs and tight deadlines. [22] GE can put your fears to rest by confidently walking alongside you as your partner, helping to develop the industrialization of your additive machines. [33]

"We have a 3-axis CNC machine, and so if you have a curved surface, we no longer have to lay down layer by layer and cut two-dimensional approximations of the curved surface," he explained. [46] The build envelope capacity of the machine was 100 100 80 mm. [20] Since they?re capable of achieving high levels of accuracy, even on intricate shapes and geometries, these machines open up new design possibilities across a multitude of applications. [33] The Matsuura Lumex also provides a machined surface on internal structures of the work piece, which is not possible in two separate machines," Houle explained. [24]

The physical process can be full melting, partial melting, or liquid-phase sintering. [19] Selective laser melting (SLM) uses a comparable concept, but in SLM the material is fully melted rather than sintered, 3 allowing different properties ( crystal structure, porosity, and so on). [19] With Matsuura?s combination of best-in-class CNC Milling and high speed Direct Laser Melting, Matsuura has fundamentally revolutionized the AM marketplace. [24] The immediate postoperative complications were also infrequent, with a low incidence of 5.7%; this low incidence of complications was probably a direct consequence of the reduced surgical time resulting from the excellent fit of custom-made implants on bone sites. [20]

To avoid this problem, Desktop Metal designed its systems to use metal injection molding (MIM) materials with properties that are familiar to engineers. [46] "There?s already a market for the materials that we?re using in powdered metal and metal injection molding, in which millions of tons of material are made each year," said Myerberg. [46]

If you want to take a geometry that?s been designed for additive manufacturing into mass production, that?s where the Desktop Metal Production System comes in, Myerberg said. [46] One of the inventions Desktop Metal is introducing is its patented Separable Supports technology for both its Studio System and its Production System. [46] The Production System features a number of innovative technologies--such as Single Pass Jetting and Separable Supports --that are unique to Desktop Metal. [46]

Desktop Metal is working to speed the advancement of design for additive manufacturing through a partnership it established earlier this year with Dassault Systemes and its SolidWorks software brand. [46]

The technology fuses metal powder into a solid part by melting it locally using the focused laser beam. [29]
