| Abstract Scope |
Aluminum is a material of interest for additive manufacturing (AM) applications. Specifically, Los Alamos National Laboratory is interested in investigating A20X, an aluminum alloy that has been developed for use with laser powder bed fusion additive manufacturing. It is of interest because there are only a handful of studies that pertain to A20X or A205, and it is the only additive Al alloy that surpasses 500 MPa UTS making it the strongest Al powder for AM that is commercially available. LANL wishes to understand A20X characteristics, so that the internal structures of additively manufactured parts can be replaced with lattices. It would result in components that utilize less material, cost less, and maintain relatively the same strength. Therefore, a parameter study has been performed to find an optimal printing condition for producing A20X lattices on an EOS M290. In addition, these lattices were qualified via compression and tensile tests. |
