Abstract
En 中文
• Poor heat dissipation and thermal regime variations drive localized spatter intensification in L-PBF. • A contour pre-sintering strategy is proposed to mitigate spatter with minimal impact on build time. • The approach stabilizes L-PBF on multi-material substrates characterized by poor heat dissipation. • The method offers a scalable solution for spatter mitigation across diverse and challenging L-PBF applications.
