| Abstract Scope |
Additive manufacturing (AM) is rapidly expanding due to its potential for design freedom, reduced material usage, and shorter lead time for replacement parts. However, build failures are frequent, and the process to decouple the root causes of error by physical means is costly and time intensive. Alternatively, modeling and simulation (M&S) can provide scientific insight of full builds’ residual stress and distortion evolution. The Navy is highly interested in advancing M&S practices to increase efficiency of AM design and fabrication. A continuation of ongoing programs, this study has focused on analyzing and comparing the small but growing set of commercially available AM simulation codes. In particular, this talk will dive deeper into numerous finite element analysis (FEA) computational tools for full-build analysis of the laser powder-bed fusion (L-PBF) process. The results will provide Navy personnel with the tools they need to accurately predict L-PBF builds and therefore minimize build failures. |
