Setting the Standard

Formetrix’s L-40 is a patented, high-performance steel alloy designed to provide users with an unparalleled combination of hardness, ductility, toughness, and 3D-printability. The unique properties of the L-40 powder material enable users to capture the significant benefits of 3D Printing (also known as
Additive Manufacturing or AM) while delivering similar performance to conventionally manufactured components.

L-40 is designed to operate on 3D metal printing platforms using laser powder bed fusion (L-PBF) technology and is targeted at demanding applications such as tools, dies, molds, and specialty components. The material properties delivered by L-40 and L-PBF into these challenging applications are unmatched in today’s 3D Printing industry.
