LENS Materials
LENS 3D metal printers can process a wide variety of commercially available metals in power form.
| Titanium | Nickel | Tool Steel |
|---|---|---|
| CP Ti, Ti 6-4, Ti 6-2-4-2 Ti 6-2-4-6*, Ti 48-2-2*, Ti 22AI-23Nb* | IN625,IN718,IN690*, Hastelloy X*, Waspalloy, MarM247*, Rene 142* | H13, S7, A-2* |
| Stainless Steel | Refractories | Composites |
| 13-8, 17-4, 304, 316, 410,420, 15-5PH*, AM355*, 309*, 416* | W*, Mo*, N* | TiC*, WC, CrC* |
| Cobalt | Aluminum | Copper |
| Stellite 21 | 4047 | GRCop-84*, Cu-Ni* |
* Materials used in R&D
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.
