摘要： The invention relates to additive manufacturing field and laser shock peening (LSP) field, in particular to a combined apparatus for layer-by-layer interactive additive manufacturing with laser thermal/mechanical effects. In the apparatus, a LSP module and a SLM module operate in alternate so as to perform LSP for the formed part in the forming process of the formed part, and thereby a better strengthening effect of the formed part is achieved. The invention effectively overcomes the challenges of “shape control” against deformation and cracking of the formed parts incurred by internal stress and “property control” against poor fatigue property of the formed parts incurred by metallurgical defects during additive manufacturing, improves fatigue strength and mechanical properties of the faulted parts, and realizes high-efficiency and high-quality holistic processing of the formed parts.
