LENS Materials

The LENS 3D printer can process a wide variety of metals including titanium, nickel-base superalloys, stainless steels and tool steels – all of which are commercially available in the required powder form.

The results from LENS consistently demonstrate better metallurgical and mechanical properties than other processes due to an improved microstructure. For example, LENS-deposited 316SS typically has a cellular spacing of just a few microns, which leads to yield strengths approaching twice that of conventionally processed 316SS.
