Support-free fabrication of overhanging structures in laser powder directed energy deposition using hybrid planar and nonplanar slicing

This study aims to address the challenge of support-free fabrication of large-angle overhanging structures in laser powder directed energy deposition (LP-DED), where geometric constraints and process instability often lead to failure. A hybrid slicing strategy integrating planar and nonplanar toolpaths is pr...
