Abstract

En 中文

• Proposed a dual-scale heat dissipation framework for LPBF thermal behavior. • Identified two key physical parameters to quantify support-process interactions. • Established quantitative links between support distribution, strength, and processing quality. • Elucidated the thermomechanical mechanisms of support structures during LPBF.
