Additive manufacturing processing with ultra-short-pulse lasers

Additive manufacturing (AM) technology has garnered significant attention for its ability to fabricate three-dimensional (3D) products with complex geometries. While continuous wave (CW) lasers have traditionally been used in AM as heat sources, they face limitations in nano and micro-scale fabrication due to the diffusion of thermal energy, which results in heat-affected zones, residual stress, substrate degradation, poor dimensional accuracy, …
