摘要

In order to meet the demand for low-cost and rapid prototyping of micro-small parts for highly dynamic microsystems, metal additive manufacturing technology has become one of the important means of manufacturing heterogeneous parts. In this paper, the residual stress and deformation generated by the rapid prototyping process of micro-small and complex parts under different laser frequencies are firstly simulated and analyzed, and then in order to check the resistance of the parts to high overload, the densities and hardnesses of the printed parts are experimentally tested. The results show that, on the basis of ensuring that the powder can be fully melted, the lower laser power, the smaller residual stress of the micro-small complex parts, the smaller deformation of the parts caused. The physical energy density also shows a certain correlation to the density and hardness of the specimen, the higher physical energy density, the higher density and hardness of the specimen.
