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 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. [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. [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] 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. [6] 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). [3] As mentioned in the beginning, Direct Metal Laser Sintering (DMLS) may not be the right fit for your particular project or application. [3] 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. [3]

Expense and time are the third factor: Direct metal laser sintering (DMLS) machines cost a great deal, and they require a lot of steps postprocessing, usually including some sort of hot isostatic pressing and removal of support structures from the build plate. [7] Some SLS machines use single-component powder, such as direct metal laser sintering. [8]

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] 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]

Whether you know it as direct metal laser sintering, electron beam melting or selective laser melting, typical tolerances using powder bed fusion are around +/- 0.005 inches with a surface finish comparable to an investment casting (figure around 125 Ra, in the best case). [9] Direct metal laser sintering (DMLS) is one of the best known names for laser sintering. [10] It is similar to direct metal laser sintering (DMLS); the two are instantiations of the same concept but differ in technical details. [8] 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. [11]

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. [12] A high-quality laser sintering machine can cost well over $1 million, and that does not cover maintenance and post-processing of parts. [10]

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. [13] At left, above, are medical parts produced using direct metal laser sintering. [14] Direct Metal Laser Sintering (DMLS) is an additive manufacturing process. [15] 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. [13]

Powder Bed Fusion is a popular technique for metal additive manufacturing and includes two main technologies: Laser Sintering and Electron Beam. [10] 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. [8]

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. [16] The Direct Metal Laser Sintering (DMLS) machine supports automation and custom configuration with a variety of options. [17] 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. [18] 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. [19] 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. [20] There are a number of different powder bed systems, including Direct Metal Laser Sintering (DMLS), Direct Metal Laser Melting (DMLM) and Electron Beam Melting (EBM). [21] Additive Manufacturing of metals originated in the early 1990’s through a process known as direct metal laser sintering. [22] Whether you call it direct metal laser sintering (DMLS), selective laser melting (SLM), laser metal fusion (LMF), or any of the other provider-specific acronyms, it uses a laser to melt metal powder roughly the consistency of flour one paper-thin layer at a time. [23]

With direct metal laser sintering (DMLS) processes, engineers can continue reducing weight, while achieving well-designed complex parts that are often too difficult to machine. [24] Advances in direct metal laser sintering (DMLS), for instance, now enable automakers to create more complex assemblies and intricate parts, such as engine components, that have the properties of metal and would otherwise be too costly or difficult–or even impossible–to machine. [24]

Streamline your manufacturing with precision metal prototypes and low-volume metal production parts that would be impractical or cost prohibitive to machine. [25]

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. [8] Use the chart below to explore the different material options available for use during the Selective Laser Sintering process. [26]

For polymers, it is concentrating on direct laser sintering and fused deposition modeling while also exploring other processes. [27] Founded in 1999, Proto Labs specializes in rapid prototyping using three additive processes: stereolithography, selective laser sintering, and direct metal laser sintering. [28] For our discussion lets focus on 5 ways Additive Manufacturing (AM) using Direct Metal Laser Sintering (DMLS) can benefit the Automotive Industry. [29] Familiar laser-based systems are known as Selective Laser Melting (SLM), Direct Metal Laser Sintering (DMLS) or Direct Metal Laser Melting ( DMLM ). [30] Sodick’s OPM250L combines direct metal laser sintering (DMLS) with high-speed milling and is primarily designed for moldmakers. [31]

By material, the selective laser sintering equipment market has been segmented into metal and nylon. [16]

These methods include “laser engineered net shaping,” “directed light fabrication,” “direct metal deposition” and “3D laser cladding.” [32] This impressive machine, the Markforged Metal X, uses their patented ADAM (Atomic Diffusion Additive Manufacturing) technologies to create metal parts at a very low cost. [33]

Selective Laser Sintering (SLS) is an additive manufacturing process. [15] 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). [34] 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. [31]

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. [16] The overall selective laser sintering (SLS) equipment market is projected to witness significant growth during the forecast period. [16] A smaller version of EOS’s M 290 system, the M 100’s laser sintering systems manufacture a variety of engineering, industrial, and medical products, including spinal implants, automotive heat exchangers, and customized wristwatch cases. [35]

Like cobalt chrome, titanium?s biocompatibility makes the metal a viable option for medical applications, particularly when direct metal contact with tissue or bone is a necessity. [21]


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. [3] 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. [3] 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. [36] 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. [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. [2] Directed energy deposition (DED) or laser metal deposition (LMD) is a powder-fed system. [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. [36] This groundbreaking hardware tandem is making metal additive manufacturing much more affordable and capable of producing parts faster. [37] It creates fully functional parts out of metals such as Cobalt Chrome, Stainless Steel, Titanium, Inconel, and many others. [3] 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. [37]

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]

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. [37] The Metal X offers a build size of 250 x 220 x 200, and a layer height of 50 microns. [37]

With a more inviting price point than other 3D technologies, 3D additive metal extrusion manufacturing has the potential to transform metalworking. [36] DMLS metals offer similar properties that industries such as aerospace, medical, and energy heavily rely on for efficient production. [5] Services often turn to other companies that are specialized in metal production to finish the order. [37]

Even mixing different materials, like plastics and metals into the same object, will be possible. [37] Metal binder jetting applies a liquid binding resin onto a powdered metal material. [37] Metal Additive Manufacturing is more than proof of concept or prototype. [1]

It sends a highly concentrated metal powder stream through an extruder, which is immediately met with a laser at the surface of the part. [37] The metal powder needed to actually build something is often proprietary, as are the lasers used to sinter it into useful products. [36] 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. [37] 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. [37] 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. [37]

DMLS is an optimal process for these parts as both manufacturing time and cost are reduced as volume decreases. [3] You can post-process binder-jetted parts to make them stronger, but this will cost you some additional time. [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. [36]

Rapid or continuous revisions – Product development efforts and iterative designs are well-suited to DMLS because there are no setup costs as in traditional manufacturing. [3] Without worrying about setup costs for each run, DMLS gives you incrementally more design revisions within budget. [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). [3] Since the metals are the same as those used with MIM, aerospace and medical oversight approvals are much easier to attain. [36] Build tough and hardworking metal prototypes to test components in real-world applications. [2] While you can?t really fuse metal filament on your desktop, very large industrial metal manufacturers can. [37] This metal alloy has a very high specific strength. (That?s strength divided by density, which basically indicates the force required per unit area). [37]

These machines are much less costly, relatively easy to use and produce fully dense metal parts suitable for end-use applications. [36] Granted, such a machine will deliver only hobby-grade accuracy, but it does give the user valuable experience with processing additively manufactured parts. [36] High complexity – Difficult to machine parts, custom medical pieces, hollowed or lightweight parts, and artistic pieces fall in this category. [3]

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. [36] Hanson, who is the proprietor of KAHMCO LLC, has more than 35 years experience in manufacturing, machine tools, fabrication and ERP systems. [36] We utilize tools like coordinate measuring machines, probes, cutup metallography processes and flow benches, hydrostatic pressure testing machines to guarantee quality is consistently met. [2]

Fabrisonic?s production machines are three-axis CNC mills, which have an added welding head for additive manufacturing. [37] AM machine builder ExOne, for example, offers a variety of binder-jetting machines and materials ranging from bronze to tungsten. [36] 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. [2]

The 2000 has two lasers and an even larger build volume of 800 x 400 x 500 mm. [37] The process is comparable to welding with a very fine and precise laser. [5] 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. [36]

DMLS materials build fully dense, corrosive resistant and highly robust metal parts that can be further treated through heat, coating and sterilization. [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. [2] The parts created with DMLS have mechanical properties equivalent to a cast metal part. [37]

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]

Unlike the startup cost (which is applied to most materials), this cost vanishes when the price is higher than the minimum price. [12] The Production System also uses the furnace for post-processing, and costs around $360,000 (furnace not included). [37] The Studio System, along with the furnace and cloud-based software, costs around $120,000. [37]

Several new technologies including hybrid metal and polymer materials are edging into powder bed territory, promising lower costs, greater accuracy and much faster build speeds. [9] 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. [8] 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]

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. [10]

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. [8] There are typically fewer than a dozen widely available materials in use for metal additive whereas metal casting can use hundreds of different alloys–and it’s really easy to use new custom materials, even for a single part in a high-volume project. [7] The practical advantage is that very few other metal additive manufacturing techniques can produce fully dense parts with properties approaching wrought material. [10] 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. [38] 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. [38]

Today, commercially available machines can build parts the size of a canoe and deposit 20 pounds of metal per hour. [9] SLM and DMLS can produce parts from a large range of metals and metal alloys including aluminum, stainless steel, titanium, cobalt chrome and inconel. [39] Sand casting doesn’t produce as fine of features, but it can make much larger parts than metal additive or investment casting: parts that can weigh tens of thousands of pounds and measure tens of feet. [7] Wohlers contrasted that with a laser based additive process by which metal is welded to metal. [38] These methods include ‘Laser engineered net shaping’, ‘directed light fabrication’, ‘direct metal deposition’ and ‘3D laser cladding’. [11] 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. [39] 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. [8]

Because finished part density depends on peak laser power, rather than laser duration, a SLS machine typically uses a pulsed laser. [8] “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. [38] That means buying more machines to do more of the same laser welding techniques that produce those properties in a part. [38]

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. [38] The high machine cost is amortized with each build, and passed through to each part created. [10] 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. [38] For most applications, machine amortization alone for PBF causes part cost to be prohibitively expensive. [10]

Since the product lies in a bed of powder, no supports are necessary saving cost in materials and allowing faster 3D part production. [26]

“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. [38] 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. [10] In the world of metal additive manufacturing, cost is, by far, the number one barrier to entry. [38]

This post is part 3 of a guide by 3DEO meant to introduce engineers and designers to metal additive manufacturing. [10] Metal SLM and DMLS parts have almost isotropic mechanical and thermal properties. [39] “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. [38] “Desktop Metal is really rethinking the way that parts might be made,” said Wohlers. [38] One of the inventions Desktop Metal is introducing is its patented Separable Supports technology for both its Studio System and its Production System. [38] The Production System features a number of innovative technologies–such as Single Pass Jetting and Separable Supports –that are unique to Desktop Metal. [38] 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. [38] 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. [38] Building on this idea lets you benefit from a trifecta of technology: Using generative design and digital optimization can generate high-performance geometries in the computer realm; nonmetal additive manufacturing brings that shape into the physical space as a mold; and modern casting methods finalize that shape using the right metal for the job. [7] Terry Wohlers also believes the technology has the potential to help the metal additive manufacturing industry. [38] We believe the benefit of this technology covered by the patents will enable substantially increased adoption of metal additive manufacturing.” [38]

“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. [38] The process requires big machines, complicated systems, and powdered metals that need to be controlled. [38]

The bed is filled with powder, the build plate is clean and the metal is ready to melt. [9] SLM sinters powders making it useful for alloys as opposed to SLS which processes single element metals and certain alloys. [11] The materials used in both processes are metals that come in a granular form. [39] UPM is a relatively new method that can operate with metals but also a variety of other materials. [11]

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). [38] 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. [8] 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.” [38] 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] Each of 3DEO?s machines uses dozens of sensors and cameras that collect operations data as parts are built. [38] 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.” [38] Machine costs are a fraction of those of powder bed or hybrid machine tools. [9] What size machine do you need, which technology is best and how big is your budget? You can figure it will cost $1 million or more, not counting the learning curve. [9] The speed of the Production System drives total cost down by eliminating the need to buy more machines to increase production. [38]

What makes the Production System able to compete at the cost target of traditional manufacturing processes? One reason is its use of low-cost materials (MIM powders) from existing supply chains. [38] Speed translates directly into cost now because you?re competing with traditional manufacturing processes like stamping and casting, where you would normally have to tool up a die, dedicate that die to a single geometry, a single part, and then move forward. [38] 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. [38] Finished parts resemble MIM parts, but are created without the cost of creating a metal injection mold. [38]

Beyond cost, PBF is a relatively slow process and it can take days or even weeks to create large parts. [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. [10] 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. [10]

SLS technology uses a laser to harden and bond small grains of nylon and elastomer materials into layers in a 3D dimensional structure. [26] The technology deposits powders and uses lasers to heat them into shape onto a platform. [11]

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. [10] 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. [39]

The tool is a laser, the material is a pile of metal powder and the fixture is a flat metal plate. [9] 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. [25] Titanium and other metal powders are reactive, especially when blasting them with high-powered laser light, so follow the manufacturer?s recommendations to avoid explosions. [9]

When the build process is finished, the parts are fully encapsulated in the metal powder. [39] The part is built up in a “green” state before being placed into an oven for sintering, which is a bit different from the decades-old metal injection molding process. [9] Once 3DEO?s Intelligent Layering process is complete, the part goes into a MIM furnace for sintering. [38] Next, the completed part is put into a high-throughput furnace for sintering. [38]

“That becomes a fraction of the overall cost of the parts, and then the bulk of the part cost is in the material. [38] The real key to the accessibility of the Production System is the fact that it competes at the cost target–usually the cost target level of all other traditional manufacturing–and it produces parts that are well understood in their properties.” [38] At up to 100 times faster than existing technologies, the Production System unlocks the cost per part needed for mass production. [38]

If a product that normally consists of 50 different parts of an assembly can be designed to require only half as many parts, that can have a dramatic impact on cost, he said. [38] For this reason, minimizing the part volume and the need for support is key to keeping the cost as low as possible. [39] This will increase the amount of required support, the build time, the material waste and (ultimately) the total cost. [39] “We?re tapping into that supply chain and getting low cost materials that we can use as is.” [38] “We have a very low cost spray head, and we use that to bind the entire layer. [38] We?re a technology company because we?ve actually invented this new, kind of breakthrough, low cost technology that we use for ourselves.” [38]

Produce optimized jigs and fixtures at lower costs. 3D Systems’ solutions offer flexible, fast turnaround manufacturing to speed up processes while improving quality. [26] We specialize in manufacturing low/medium volumes on demand, which means there?s no need to worry about long lead times, minimum order quantities, or high tooling/setup costs. [10]

“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. [38] They might have hundreds, or even more than a thousand, million-dollar machines in a factory producing aerospace parts. [38] “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.” [38]

Most SLS machines use two-component powders, typically either coated powder or a powder mixture. [8] There?s plenty more to be aware of with powder bed fusion, especially for those operating the machines. [9]

“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. [38] 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. [38]

“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. [38] In ball milling, a machine is used to grind and blend materials via high impact. [26]

It was originally used by NASA to build metal objects in space. [11] SLS, while mostly used for plastics, can also be used for certain types of metals. [11] Nitrides, metals and composites have been used for this method. [11] Here are some of the most common types used to digitally craft metal objects. [11]

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. [38] To be fair, there are several reasons why manufacturers are sticking with traditional manufacturing techniques, such as metal casting, rather than diving into metal additive manufacturing. [7] PBF is a currently the most common and well known form of metal additive manufacturing. [10] 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. [38] 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. [38]

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. [8] “Even if they (Desktop Metal) are half right, that could really make a difference,” said Terry Wohlers. [38] As a result it can work with such a diverse range of metals. [11] A metal bracket before support removal oriented in a 45 o angle. [39] This is a great method for transforming nearly liquified metals into new shapes. [11]

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. [39] 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. [39] According to 3DEO, the Intelligent Layering process begins by spreading a thin layer of metal powder over the build area. [38]

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). [38] 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. [38] 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). [39] 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. [38]

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. [38] 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. [38]

The laser traces the pattern of each cross section of the 3D design onto a bed of powder. [26] LENS lasers can range from 500W to 4kW. The process has been used to process titanium, stainless steel and Inconel. [11] Lasers and electron beams heat particles of titanium, aluminum, stainless steel, cobalt chrome, tool steel and dozens of other alloys to their melting points, which can exceed 2,700 degrees. [9] Both methods make use of lasers to arrange a wide spectrum of alloys. [11] A material or wire is heated with a laser on top of an existing object, soldering them together when using any DED method. [11] Skin and cores are processed using different laser power and scan speed, resulting in different material properties. [39]

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. [8] Laser cutting in India, which is done through emission of radiation, has gained popularity due to its simplified process. [40] To make your work easy, you can hire laser cutting services. [40] Many laser cutting services in Pune are providing superior work to their clients. [40]

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). [8] To avoid this problem, Desktop Metal designed its systems to use metal injection molding (MIM) materials with properties that are familiar to engineers. [38] Since it uses the same metal powder, it receives nowhere near as much metallurgical scrutiny as other additive powders. [9] “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.” [38] In SLM and DMLS almost all process parameters are set by the machine manufacturer. [39] The PBF process is quite complex, which results in very expensive machines. [10]

An SLS machine being used at the Centro Renato Archer in Brazil. [8] “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. [38] 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. [10] Earlier, the work which was done manually has now been done through machines. [40]

It?s important for engineers to learn how to design for the process because the costs of products are heavily tied to their design. [38] For example a kilogram of stainless steel 316L powder cost approximately $350 – $450. [39] It uses a low cost spray head that lacks the complexity of an inkjet and leverages established technologies like CNC milling for excellent repeatability and reliability. [38] This precludes it from being useful in most production scenarios due to the low throughput and high cost. [10]

What does it take to adopt 3D and metal together? Embracing new engineering approaches and getting used to new materials such as metal powders, for starters. [9] The technology works on iron, cobalt-based, nickel-based alloys, tungsten carbide and other metal powder coated metal. [11] The metal powder in SLM and DMLS is highly recyclable : typically less than 5% is wasted. [39] Millions are jetted per second, binding metal powder to form high resolution layers. [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. [39]

“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. [38] By introducing technology to make metal parts with well-established properties, Desktop Metal enables engineers to quickly validate their parts. [38] A finished metal part produced on Desktop Metal?s Studio System. [38] If you can feel the power of Desktop Metal?s claim that it?s reinventing how metal parts are manufactured, you?re not alone. [38]

It might also mean that the range of metal parts suitable for additive is getting ready to expand.” [9] “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. [38]

It is useful for strengthening, repair, regeneration or direct manufacturing. [11] The physical process can be full melting, partial melting, or liquid-phase sintering. [8] There?s little need for support structures, and the ones that are used can be popped off easily after sintering. [9] Anti-sintering agents are then deposited, making it possible for supports to fall off after sintering, saving hours of post processing. [38]

At launch, Desktop Metal announced that it had developed a microwave sintering technology that could quickly and evenly sinter parts. [41] 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. [42] 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. [13] DMLS creates fully functional parts out of metals such as Cobalt Chrome, Aluminum, Stainless Steel, Tool Steel, Titanium, Inconel, and many others. [42] DMLS uses a high-wattage laser to micro-weld powdered metals and alloys to form fully functional metal components. [13] Unlike other laser and powder based additive technologies, DMLS parts move around in the build envelope if not properly secured to the build platform. [42] 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. [14] “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.” [41] 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. [14]

“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. [41] The wire-fed approach only produces parts to near net shape, after which excess metal must be machined away. [27] Part designers must take all this and more into consideration before jumping onto the Desktop Metal bandwagon. [14] This involves propelling liquid metal from a chamber at scorching temperatures of 1200C to create parts. [33]

With conventional manufacturing, making metal objects can be a wasteful process. [32] 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. [14] Plus, it took many years for the metals used with DMLS to pass muster for use in aircraft and human bodies. [14] Eaton is chiefly interested in DMLS, EB, DED and cold spray techniques for metal additives. [27] Eaton has identified manifolds, valves, filtration components and other products as candidates for metal additives. [27] Eaton maintains a center of excellence in Southfield, Michigan, for developing both polymer and metal additives. [27]

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). [13] 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.) [41] 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. [42]

The EBM process melts metal powder with an electron beam to build parts layer by layer. [13] 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). [14]

It allows designers and engineers to combine multiple components in production, minimize material use, produce complex parts and reduce tooling costs. [32] Not so with injection molding, machining, casting, and other traditional manufacturing processes, where complex part designs make production costs skyrocket. [14] Julie Van Kleeck, vice president of advanced space and launch programs at Aerojet Rocketdyne Inc., said: “The use of additive manufacturing technology reduces the cost to produce components, shortens build times and unleashes engineers to design components that were once impossible to build using traditional manufacturing techniques.” [32] This layer by layer approach allows for the fabrication of complex parts that have been impossible or cost prohibitive through traditional manufacturing methods. [15] For polymers, its investigations include replacing some aluminum parts with additive polymers to save costs and reduce weight. [27] The big difference is that DM requires no mold or other tooling like MIM. This increases flexibility, shortens lead time and, on lower part quantities (say anything under 1,000 pieces, depending on part complexity), reduces part cost. [14] The first can cut costs, while the second speeds parts to market, eliminating the need for massive inventories. [27]

Fuller says his company?s three Norwegian machines and nine New York machines can thus all guarantee production of the same part every time. [27] Prior to being sent to the DMLS machine, part support structures are designed and built. [42] Movement of the part during the build will cause failures in part accuracy and could potentially lead to machine crashes. [42] 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. [41] High complexity – Difficult to machine parts, custom medical pieces, hollowed or lightweight parts, and artistic piece fall in this category. [42] The company is now deciding whether its next machine will aim for larger parts or just more complex ones. [27]

Preparation of the design before being sent to the DMLS machine and the post processing afterwards can be time consuming. [42]

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. [42] LMD is similar to melting or sintering tech, which deposits powders and uses lasers to heat them into shape onto a platform. [32] The laser goes to work rendering the first 2D layer, sintering it into a solid form. [15]

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. [14] After the first layer is sintered, the build platform lowers, another powder layer is spread, and the laser sinters the second layer. [15]

GE acquired 75% of Concept Laser in December 2016 and the company now operates under the GE Additive umbrella. [33]

For this reason, Markforged is not overpromising the metals that will work with the ADAM process. [41] They’re just not as stable and repeatable as a thermal process for metal. [41]

The Metal X system could open up the possibility of batch production. [41] 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. [41] Metal is the last piece you need to fill in the design space,” Mark said. [41] Because DM leverages the same well-understood metals used with MIM, the certification road should be much shorter, but it must be traveled nonetheless. [14] EBAM works by placing metal wire feedstock into a vacuum and heating it with an electron beam. [13] Desktop Metal are an American startup which has raised over $277M in investment so far, from companies including Google, BMW, Ford, GE, and more. [33] Since being founded back in 2015 by CEO Ric Fulop, Desktop Metal has expanded to hire over 160 people. [33]

A Boston based company, Desktop Metal, has opened up pre-orders for its Studio System, which uses inkjet-like technology, rather than laser-based techniques, to produce precision metal parts. [32] 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. [14] Stratasys also claims that DMLS parts are stronger and more dense than investment casted metal parts. [13]

Put simply, it?s a quick and effective process used to create three-dimensional metal parts from a digital file. [32] Escape holes Holes are required on hollowed metal parts to remove unmelted powder. [42] Ideal for complex, high-performance metal parts, the Production System™ delivers the speed, quality, and cost-per-part to compete with traditional manufacturing processes. [43]

Because it is using wire, Norsk is not paying the exorbitant costs of metal powders. [27] In this example the important features of a mold are built using DMLS and the surrounding material is milled to save on overall assembly cost. [42] Rapid or continuous revisions – product development efforts and iterative designs are well-suited to DMLS because there are no setup costs as in traditional manufacturing. [42]

Traditional methods meant complexity increased cost, in either manufacturing or welding. [27] With other methods of prototyping to produce an item compromises are made that sacrifice appearance, cost, design, physical properties, and or dimension thresholds. [15]

Titanium wire costs more per kilogram than titanium block, Fuller acknowledges, “but not dramatically more.” [27]

Because you’re bulk sintering the entire part at the same time, there isn’t this locked-in stress. [41] 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. [41] The resulting porous, “brown” part is subsequently placed in a sintering furnace (Markforged has its own furnaces, the Sinter-1 and Sinter-2). [41] The system also consists of a debinder that prepares green parts for sintering by dissolving primary binder. [13]

FDM machines offer a greater number of material options than SLS and MJF combined. [14] The current Norsk machine has a work envelope of 900 X 600 X 300 mm (35 X 24 X 12 in.). [27] CNC, for example, requires the programming of tool paths, machine setup, cutting and grinding, then polishing and de-burring afterwards. [42] The first machines are being shipped at the moment to a variety of customers who paid around $120,000 for each Studio System, and $320,000 for a Prodution System. [33]

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. [41] It?s useful for strengthening, repair, regeneration or direct manufacturing. [32] At this point, the technology works on iron, cobalt-based, nickel-based alloys, tungsten carbide and other metal powder coated metal. [32] DMLS and other metal powder bed fusion technologies are notoriously complex, often leading to repeatability and quality issues. [41] A blade spreads the metal powder creating a uniform thickness over a build platform. [15]

Regardless of platform, the process is similar in capability and product integrity to the decades-old metal injection molding (MIM) process. [14] This fuses the individual metal particles one to another in a manner similar to metal injection molding (MIM). [14]

There is much more to come in additive manufacturing for aerospace as 3D metal parts proliferate. [27] The Studio System is a three-part solution aimed at allowing engineers to rapid prototype metal parts without the need for outsourcing. [13]

This process uses laser toolpaths to weld powdered metals into three dimensional parts. [22] Powder bed fusion (PBF) is an additive manufacturing (AM) process in which ultra-fine layers of powdered metal are sequentially spread across a build plate before being melted by a laser. [21] 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 technology fuses metal powder into a solid part by melting it locally using the focused laser beam. [19] Companies such as AutoDesk and 3DSystems have developed simulation software that offers a predictive view of what happens when laser beam meets metal, and continuously improving the outcome. [23]

Hot-work stainless steels are high-load metals ideal for use in the production of parts used in high-volume injection molding. [21] In such processes, build material flow rates are optimized through the use of closely packed, spherical metal particles of similar size. [21] The APA uses plasma torches to melt and atomize the metal wire feedstock, allowing for an accurate feeding rate with excellent control over powder size distribution and batch-to-batch consistency. [21]

Due to rapid cooling of the metal melt pools, Ti6Al4V parts exhibit a fine-grained, dense microstructure that often exceeds that found in investment cast parts. [21] 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. [22] Although less commonly used, plasma atomization is used with reactive metals that have very high melting points, like titanium alloys. [21] The advanced metal alloy is also used in extremely demanding cryogenic and aerospace applications. [21]

Look out for a Cimquest special edition with everything you will need to know about running a Desktop Metal machine. [22] The problem remains the cost, a factor that everyone in the industry knows automakers are sensitive to; even if thousands of machines were purchased and production scaled up to the point that part runs in the millions became possible, the sad reality is that current powder bed fusion technology would remain too expensive for mass production of commuter car and F-150 pickup truck components. [23] 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. [17] Renishaw, Concept Laser, and various other machine builders are doing this by adding more lasers to their wares, and using them to build multiple parts at one time, or make a team effort approach and build a single part more quickly. [23] Featuring some of the most advanced additive technologies available, machines from Arcam EBM and Concept Laser enable customers to grow products quickly and precisely. [21]

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. [17] Depends on material, machine space, and number of parts (labor). [18] The result is optimized lubrication during grinding, increased service life of the grinding wheel, and quick and easy parts assembly during machine production. [17]

For Shapeways, service cost includes the materials used, machine space and labor. [18] At some point, you might think that owning a machine will help you save more, but this also depends on how frequent you need it and how much the maintenance cost is. [18]

Find information on the different materials that can be used with GE Additive’s additive manufacturing machines. [21]

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. [44] Renishaw signed a partnership agreement with FalconTech Co., Ltd. (China) for extending the distribution of its solutions based on metal additive technology in China. [16] 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. [35] For each layer, the laser beam traces a cross-section of the part pattern on the surface of the liquid resin. [19] There?s no bottom-up layer building with Carbon, nor lasers tracing part outlines and patiently filling in the spaces between. [23] With its ability to make small metallic parts, the EOS M 100 uses a powerful laser to create durable parts accurately and reliably. [35]

Stereolithography is an additive manufacturing process which employs a vat of liquid ultraviolet curable photopolymer “resin” and an ultraviolet laser to build parts’ layers one at a time. [19] PBF systems either utilize a laser, multiple lasers or a beam of electrons to selectively melt thin layers of build material about 20 to 100 microns thick. [21] It uses a powerful laser and steerable mirrors to precisely trace the item under construction out of a bed of powdered raw material. [35] The report covers the SLS equipment market segmented by laser type, material, application, industry, and geography. [16]

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. [35] Among the materials, you can choose from are plastics, resin, precious metals, steel, ceramics, woods, titanium, 18K Gold and more. [18] Titanium Grade Two is a metal offering a desirable balance between formability and strength. [21]

The mechanical properties of Inconel 625 are considerably enhanced by the use of significant amounts of nickel, chromium and molybdenum in the metal. [21] The hardening process generates precipitates that better secure metal grains in place. [21] In the gas atomization process, molten metal shooting from a nozzle is dispersed and solidified by a stream of nitrogen or argon gas. [21]

Wire filament is melted with a plasma torch, resulting in the production of spherical particles as the molten metal cools. [21] Additive Industries will share its metrics for productivity growth in metal additive manufacturing at the 2018 Additive Manufacturing Conference. [17] With the Desktop Metal Studio Solution, many of these traditional obstacles are eliminated. [22] Ti6Al4V ELI is commonly used in offshore oil and gas extraction applications, where the metal alloy?s extreme resistance to stress corrosion cracking in salt water is an advantage. [21] Since the metal powder and sintering process Markforged employs is virtually identical to that used by metal injection molders for the past fifty years, there should be little problem with acceptance within the engineering and quality communities. [23] By replacing the filament with a metal-infused thermoplastic and then sintering the finished product in a high temperature oven, the plastic binder melts away in a manner much like metal injection molding (MIM). [23]

In this sintering phase, the part shrinks by roughly 20% and densifies to between 96 and 99.8%. [22]

Since AM processes allow for direct manufacturing from CAD files, it is possible to economically produce customized components and smaller quantities of parts. [21] Without requiring tools, EOS systems make direct use of digital CAD data to produce polymer parts of the highest quality. [20]

Designers can also optimize the use of valuable build materials to simultaneously reduce weight, retain structural strength and cut costs. [21] If I can guarantee the quality of any given component at the completion of the build, that?s in turn a huge step for reducing costs, no matter what you?re making.” [23]

The cost, time and labor will be greatly reduced by using this technology. [18] All of these requirements result in a high startup cost that can discourages widespread adoption of the technology. [22]

This reduces the cost of production significantly and reduces the risk of quality defects by eliminating variation from different operators, different equipment setups, and the logistics of multiple processing steps. [19] For example, a ring measuring 23 x 11.6 x 23mm will cost $8.37 from Sculpteo, $9.34 from Makerbot Replicator 2x, $11.01 from Formlabs Form 1 and $33.10 from Stratasys Mojo. [18]

Tom Houle, director of Matsuura Machinery ?s LUMEX line of hybrid machines, says automotive OEMs and their suppliers alike are pushing hard on additive technology for this very reason. [23] GE can put your fears to rest by confidently walking alongside you as your partner, helping to develop the industrialization of your additive machines. [21]

In addition to displaying what the machine is currently doing and its raw material supply level, any faults are indicated. [35] The center of attention with the M 100 is its large color screen that presents a process flow overview of the machine. [35] “These will require continuing collaboration between the machine builders, the OEMs and their Tier 1 and Tier 2 suppliers, but there?s definitely a good deal of interest in the mass production of automotive parts.” [23] In many cases, machine metrics and build data are continuously fed to cloud-based servers for predictive maintenance purposes, and regular software updates pushed downstream to the end user. [23] 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. [21] That said, the M 100 machine is the size of a refrigerator at 31 x 37 x 89 inches and weighs 1,300 pounds. [35] 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. [35]

GE Additive (parent company of Concept Laser) established Customer Experience Center in Munich, Germany. [16] Learn more about GE Additive, including information on our history, leadership team, and how we have come together with Arcam and Concept Laser. [21]

Exposure to the ultraviolet laser light cures and solidifies the pattern traced on the resin and joins it to the layer below. [19] At 200 watts, the ytterbium laser has a focus spot of 40 microns and builds the object in precise 30-micron slices. [35]

One key advantage of aluminum alloy powders is that they typically offer better build rates than other metal powders used in PDF processes. [21] Market pressures and increased use will help in this regard, but GE Additive is one of the many manufacturers either developing their own metal powders or working with suppliers such as Carpenter, Sandvik, and TLS in an effort to make gas atomized alloys more affordable. [23]

As each pass is completed, a fresh layer of metal powder is spread across the previous layer and the process begins again until the workpiece is complete. [23] This includes ensuring that the EBM and LaserCUSING parameter settings (process themes) are optimized to work well with the metal powder used. [21] A variety of stainless steel metal powders are used in AM processes like DMLM, including 316L (low-carbon), 17-4PH, hot-work and maraging steel. [21] Farsoon Technologies signed an agreement with Oerlikon to supply qualified Oerlikon AM metal powders for Farsoon additive manufacturing metal systems. [16] Additive manufacturing system for the industrial production of high-quality metal parts. [20] Inconel 718 is used to produce metal parts used in gas turbines, jet engines, cryogenic storage tanks and petrochemical applications. [21] Nickel chromium super-alloys like Inconel 718 and Inconel 625 produce strong, corrosion-resistant metal parts. [21]

Inconel 625 is frequently used in metal parts used in marine applications. [21]

While effective, the technology has major barriers to entry due to the volatile nature of metal powders. [22] ASTM International continues to work toward standardizing specifications for AM metal powders. [21] High-quality metal powder is very important for successful powder bed fusion. [21]

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. [35]
