Metal 3D Printer Powders

Produce complex metal parts quicker and with fewer tools and less wasted material than machining. The parts made with these powders look virtually the same as machined parts, are easy to weld, and resist corrosion. However, since they’re rapidly heated and cooled, they can form internal stresses and pores that make them more brittle than machined parts. These powders include a material certificate with a traceable lot number and test report that confirms their material composition. All were produced in facilities that meet ISO standards for quality.

Use them with powder bed fusion (PBF) printing systems, such as direct metal laser sintering (DMLS), selective laser melting (SLM), and electron beam melting (EBM). Their parts cannot be heat treated.

316/316L Stainless Steel

With added molybdenum, 316/316L stainless steel powders create parts that resist rusting and cracking from corrosion better than 718 nickel. Choose them for parts that are often exposed to acids and chlorides in chemical, food, and marine applications.

718 Nickel

718 nickel powders make parts that maintain their high strength even when exposed to extreme heat or cold for a long time, thanks to their added chromium, niobium, and molybdenum. Print them into parts that must stand up to harsh conditions, such as components in gas turbines and cryogenic chambers.

Plastic 3D Printer Powders

Produce intricate parts with these plastic powders—they don’t require support materials and have more uniform mechanical properties than filaments and resins. Use them with powder bed fusion (PBF) printing systems, such as selective laser sintering (SLS).

Nylon 11

Nylon powders create long-lasting parts that resist wear and won't scratch from constant motion and friction. They resist UV light, so parts made from these powders are good for use outdoors. They also have good chemical resistance. Parts printed with these powders meet UL 94 HB, a strict standard for flammability.

TPU Plastic

TPU powders are stretchy, soft, and sturdy, so they make durable parts that resist breaking, even with repeated use. These powders are often used to make long-lasting, wear-resistant parts, such as seals, sleeves, and gaskets, as well as components that take on high-impact force, such as springs and snap-fit parts.
