Abstract As a typical laser additive manufacturing technology, laser powder
bed fusion (LPBF) has achieved demonstration applications in aerospace,
biomedical and other fields. However, how to select process parameters
quickly and reasonably is still the main concern of LPBF production. In
order to quantitatively analyze the inuence of different process parameters
(laser power, scanning speed, hatch space and layer thickness) on the LPBF
process, the multi-layer and multi-path forming process of LPBF was predicted based on the open-source discrete element method framework Yade
and the open-source finite volume method framework OpenFOAM. Based
on the design of experiments method, a four-factor three-level… More >
