PROVIDENCE, RI, June 17, 2017 – NanoSteel, the leader in nanostructured steel materials, announced the launch of its first product for the laser powder bed fusion additive manufacturing process. BLDRmetal L-40 is a case-hardening steel powder that provides high hardness and ductility (case hardness >70HRC, 10%+ core elongation) and prints easily on standard commercial equipment. This alloy provides superior performance to M300 maraging steel and is an alternative to difficult-to-print tool steels such as H13. Expanding the potential use of 3D printing in a wide variety of hard materials markets, BLDRmetal L-40 is designed to be used for parts including tools, dies, bearings and gears.

The capabilities of BLDRmetal L-40 were demonstrated by printing an 8-inch roll thread die set, which outperformed dies machined from D2 and M2 tool steels. “We tried nearly every combination of material and…
