Abstract: The parts fabricated by Additive Manufacturing (AM) cannot be used directly due to the defects caused by layer-by-layer formation of AM, including coarse surface, high residual stress, and pores/micro cracks beneath the surface caused by insufficient melting. The review summarizes the research results of the post-treatment processes of stainless steel additive manufacturing components at home and abroad and the defect types of stainless steel additive manufacturing components, analyzes the differences and uses of different additive manufacturing processes, and current domestic and international optimization progress of the process parameters of the additive manufacturing components, heat treatment, mechanical processing and other post-treatment processes, The key problems of post-treatment process of stainless steel additive manufacturing pieces are summarized, and the development trend of post-treatment process of stainless steel additive manufacturing pieces is discussed.

Key words: additive manufacturing, stainless steel material, post-processing technology, machinability, residual stress
