Abstract：Hot isostatic pressing can eliminate internal defects and residual stress of materials and improve me‐
chanical properties. As an important means of post-treatment for metal 3D printed components, it has attracted
more and more attention and developed rapidly at home and abroad. The recent progress in improving mechanical
properties of 3D printed components by hot isostatic pressing is reviewed, the main reasons for the improvement of
mechanical properties are described, and some suggestions for hot isostatic pressing 3D printed components are put
forward.
