Abstract: The present invention belongs to the field of multi-material additive manufacturing (AM), and in particular discloses a forming system and method of hybrid AM and surface coating. The hybrid forming system includes an additive forming device, a laser-assisted cold spraying (LACS) device and a workbench. The additive forming device and the LACS device are located above the workbench. During manufacturing, the additive forming device forms a part to be formed on the workbench layer by layer, and the LACS device performs coating peening treatment on inner and outer surfaces of the part to be formed during the forming process, thereby jointly completing the composite manufacturing of the part to be formed. The present invention makes full use of the rapid prototyping advantage of the short-flow AM process, and integrates the surface coating peening process into the hybrid forming system.
