Optimization of Additive Manufacturing Process for High-Precision Metal Parts

This study focuses on the optimization of additive manufacturing process for high-precision metal parts, and analyzes in-depth the problems of precision deviation, unstable material properties, and low production efficiency in the application of the current technology. Through the systematic study of key process parameters, material properties and post-processing technologies in the additive manufacturing process, this paper proposes a set of process optimization solutions that include innovative methods such as dynamic regulation of laser power, multi-angle scanning strategy and gradient heat treatment. The experimental results show that the optimized additive manufacturing process can improve the dimensional accuracy of metal parts by 28% and reduce the surface roughness to below Ra 3.2 m, while the mechanical properties of the material reach more than 92% of those of the traditional manufacturing method. The research results provide theoretical basis and practical guidance for the additive manufacturing of high-precision metal parts, which is of great significance for promoting the application of advanced manufacturing technology in aerospace, medical devices and other high-end equipment manufacturing fields.
