Designers and engineers have become accustomed to <a href=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/three-environmental-considerations-for-the-fff-3d-printing-process\/\">FFF<\/a> machines because of their accessibility, affordable price points, and because plastic is easy to come by. As the industry evolves, however, we&#8217;re starting to see metal applications become more accessible \u2014 there are even desktop metal additive manufacturing machines now.<\/p>\n\n\n\n<p>Aligned with this industry shift, Fusion 360 has introduced metal printing capabilities to its additive manufacturing space through <a href=\"https:\/\/www.autodesk.com\/products\/fusion-360\/additive-build-extension#trial\" target=\"_blank\" rel=\"noreferrer noopener\">extensions<\/a>. So, now feels like the perfect time for us to talk about metal additive manufacturing \u2014 what it is, the various metal additive manufacturing technologies available, and how this process might be helpful to you.\u00a0Read on to get the full rundown on this exciting technology.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"metal-active-manufacturing-function-and-usenbsp\">Metal active manufacturing:<strong> function and use<\/strong> <\/h2>\n\n\n<p>So&nbsp;let\u2019s start with the easiest question <meta charset=\"utf-8\">to answer: why should you care about metal additive manufacturing? Well, the most significant reasons are:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Higher part durability (metal vs. plastics) for use in prototyping and testing, or even as final parts in production.\u00a0<\/li><li>If your final part is manufactured in metal, why not prototype it in metal too?<\/li><li>Compared to traditional machining, metal additive manufacturing is relatively affordable. It can also be done on your desktop, which takes up less space than a <a href=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/cnc-coordinate-system-made-easy\/\">CNC machine<\/a> and allows anyone to prototype instead of only skilled CNC operators. <\/li><\/ul>\n\n\n\n<p>If you\u2019re new to Metal additive manufacturing, you may not be aware that there are a multitude of technologies that create metal 3D printed parts, each with its pros and cons.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"powder-bed-systemsnbsp\"><strong>Powder bed systems<\/strong> <\/h2>\n\n<h3 class=\"wp-block-heading\" id=\"slm-and-dmlsnbsp\"><strong>SLM and DMLS<\/strong> <\/h3>\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2021\/12\/image001-2-1024x576.jpg\" alt=\"dmls-metal-additive-manufacturing-technology\" class=\"wp-image-26973\" srcset=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2021\/12\/image001-2-1024x576.jpg 1024w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2021\/12\/image001-2-300x169.jpg 300w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2021\/12\/image001-2-768x432.jpg 768w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2021\/12\/image001-2-355x200.jpg 355w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2021\/12\/image001-2.jpg 1430w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption><em>DMLS process in action. Image courtesy of EOS GmBH<\/em>.<\/figcaption><\/figure>\n\n\n\n<p>If you\u2019re a seasoned additive manufacturing user, you\u2019re undoubtedly familiar with Selective Laser&nbsp;Sintering (SLS). SLS uses a form of plastic powder in combination with a laser that melts and fuses the powder along the trace of the laser path. As it layers more powder up, it fuses the layer and forms.&nbsp;<\/p>\n\n\n\n<p>SLS is the oldest and most common form of\u00a0<a href=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/fusion-360-additive-manufacturing-3d-printing-capabilities\/\">3D\u00a0printing<\/a> that uses powdered\u00a0plastics. This tech is well developed, consistent, and reliable.\u00a0For metal additive manufacturing, this technology is either Direct Metal Laser Sintering (DMLS) or Selective Laser Melting (SLM). Both technologies are built very similarly to SLS.\u00a0\u00a0<\/p>\n\n\n\n<p>SLM and DMLS&nbsp;use&nbsp;a similar process, binding&nbsp;metal together with a laser, using support materials for overhang&nbsp;angles, etc. This technology is very reliable, well developed, and produces high-quality parts.&nbsp;However,&nbsp;powdered metals are highly volatile, and if not handled properly, can explode, which is unsurprisingly very dangerous.<\/p>\n\n\n\n<p>However, new companies are bringing the benefits of DMLS style manufacturing to&nbsp;the masses, like&nbsp;Xact&nbsp;Metal,&nbsp;at a dramatically reduced cost compared to&nbsp;most other&nbsp;machines available on the market.&nbsp;These machines have considerably smaller footprints than older generations, making them more feasible for most companies.&nbsp;<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"electron-beam-meltingnbsp\"><strong>Electron Beam Melting<\/strong> <\/h3>\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"640\" height=\"360\" src=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2021\/12\/image002-1.jpg\" alt=\"\" class=\"wp-image-26978\" srcset=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2021\/12\/image002-1.jpg 640w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2021\/12\/image002-1-300x169.jpg 300w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2021\/12\/image002-1-355x200.jpg 355w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/figure>\n\n\n\n<p>With a fancy name like electron beam melting,&nbsp;it should come as no surprise that this tech is an evolution of&nbsp;laser-based&nbsp;systems as above. The core differentiator between&nbsp;laser systems and EBM is that EBM uses an electron beam. The electron beam&nbsp;fires at the powder bed, which fuses where the beam touches, creating the print layers.&nbsp;&nbsp;<\/p>\n\n\n\n<p>This tech is high-speed&nbsp;and can minimize the amount of potential deformation created in the part by keeping the powder bed heated at a stable rate so that the temperature change is not so extreme as the&nbsp;powder melts together. The&nbsp;trade-off&nbsp;here is&nbsp;accuracy and&nbsp;build volume. Electron beams are not as fine as a laser, so parts are \u201crougher\u201d than their DMLS counterparts, and currently, DMLS\/SLM machines are available with much larger build volumes than their EBM counterparts.&nbsp;<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"feedbased-systems\"><strong>Feed-based systems<\/strong><\/h2>\n\n\n<p>Full disclosure, these are my personal favorite machines, not because they\u2019re better necessarily. They look the coolest. Feed-based systems usually work with a spool or hopper of raw material.&nbsp;Spool systems work by&nbsp;melting&nbsp;and laying&nbsp;up in a fashion that will&nbsp;be&nbsp;very familiar to you if you\u2019ve used FFF&nbsp;3D&nbsp;printers&nbsp;before, but they are,&nbsp;in actuality, more&nbsp;closely related to arc welding.&nbsp;&nbsp;<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"ded\">DED<\/h3>\n\n\n<p>Hopper-based\u00a0DED\u00a0systems work by dispersing metal powder that is melted by the heat\u00a0source.\u00a0These machines\u00a0lay metal down by\u00a0firing metal particulates from a hopper into the path of a laser beam or electron beam that melts the material together on impact. The jet of raw material is usually shielded with an inert gas to protect it from the oxygen in the air (you know, to stop things from exploding), creating parts very rapidly. DED works by laying molten metal directly down on the built plate,\u00a0and then the previous layer, building\u00a0up the part.\u00a0\u00a0<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"975\" src=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2021\/12\/image003-1-1024x975.jpg\" alt=\"ded-metal-additive-manufacturing-technology\" class=\"wp-image-26983\" srcset=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2021\/12\/image003-1-1024x975.jpg 1024w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2021\/12\/image003-1-300x286.jpg 300w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2021\/12\/image003-1-768x731.jpg 768w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2021\/12\/image003-1.jpg 1430w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption><em>DED printing in progress. Image&nbsp;courtesy&nbsp;of&nbsp;RAMlabs<\/em>.<\/figcaption><\/figure>\n\n\n\n<p>DED systems are easy to deploy and print very rapidly and produce powerful parts as the process has minimal disruption to how the metals crystallize as they cool down.\u00a0However,\u00a0parts made using DED typically have very rough finishes. As a result, the majority of DED parts are post-processed in a CNC machine to give them a high finish, but this process isn\u2019t necessary, strictly speaking unless the finished form\u2019s accuracy is necessary (in most cases, it is).\u00a0<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"waamnbsp\"><strong>WAAM<\/strong> <\/h3>\n\n\n<p>Wire Arc Additive Manufacturing (WAAM) is a subset of the DED process but is worth calling out independently. WAAM applies the same principles of DED but specifically uses the technology that makes an arc welder operate. The material layers up by feeding a wire of material to a plate to create the arc. Like other DED technologies, WAAM produces parts very fast with stable material properties, but they\u2019re very rough.&nbsp;&nbsp;<\/p>\n\n\n\n<p>So that\u2019s just a few examples of metal <a href=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/20-fusion-360-additive-manufacturing-tutorials\/\">additive manufacturing<\/a> technologies. More systems are being explored, from firing metal particles at\u00a0Mach\u00a0speeds onto build plates to\u00a0nano-level\u00a0particles carried through\u00a0a liquid, fusing to each other as the\u00a0liquid\u00a0evaporates\u00a0to make parts. This process is similar to the incredible tech from <a href=\"https:\/\/www.xjet3d.com\/\" target=\"_blank\" rel=\"noreferrer noopener\">XJET<\/a> or <meta charset=\"utf-8\">what <a href=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/spee3d-spee3dcraft-fusion-360-metal-additive-manufacturing-simulator\/\">Spee3D<\/a> does. <\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"metal-additive-manufacturing-with-fusion-360\">Metal Additive Manufacturing with Fusion 360<\/h2>\n\n\n<p>As you can see, metal additive manufacturing is an exciting technology with great applications today and exciting potentials for the future.
