Mechanism of double exposure strategy for improving down-skin roughness and dimensional accuracy in support-free printing

Mechanism of double exposure strategy for improving down-skin roughness and dimensional accuracy in support-free printing

Laser Powder Bed Fusion (LPBF) additive manufacturing of support-free structures faces key technical challenges regarding down-skin quality and forming accuracy. This study first analyzed the impact of laser input energy on these factors. Subsequently, we proposed a double exposure strategy for the...
