Abstract

Laser additive manufacturing is mainly divided into selective laser melting and laser direct deposition, which can meet the individual needs and has unparalleled advantages in the manufacturing of complex components. The principle and methods of the laser additive manufacturing technology are briefly introduced. Through the investigation and analysis of relevant literatures at home and abroad, the treatment methods and processes corresponding to the internal defects such as residual stresses, cracks, spheroidization and pores of laser additive manufactured components are described. A method for solving defects in laser additive manufactured products is proposed.
