DMLS is an additive manufacturing process which 3D prints metal parts. Laser energy melts powder metals in an enclosed build chamber, layer by layer, to result in fully realized parts; imagine fine metallic sand is being zapped by space lasers, shooting out sparks of stardust as it melts designs (at least, that’s what it looks like to us). Metals Stratasys Direct Manufacturing 3D prints with include Stainless Steel 17-4PH, Stainless Steel 316L, Aluminum AlSi10Mg, Nickel Alloy 625, Nickel Alloy 718, Titanium Ti64, and Cobalt Chrome CoCrMo.
Nickel Alloy 625, Nickel Alloy 718, Titanium Ti64, and Cobalt Chrome CoCrMo are best suited for high-end, production applications. These metals will typically perform with higher tensile strengths. Aluminium AlSi10Mg can build faster than other DMLS materials. While it has good thermal properties, strength and hardness, its speed has made it a favorite among lower cost prototypes. Titanium Ti64 meets ASTM F1472 requirements. It is most commonly applied to complex aerospace designs, like engines and turbines. Cobalt Chrome CoCrMo, which has a history of meeting ISO specs for biocompatibility, has excellent corrosion resistance and is more favored for medical and dental prototypes. Nickel Alloy 625 and Nickel Alloy 718 meet identical hardness and temperature performances, with 718 yielding slightly higher for strength.
