Abstract In order to solve the problems of fixed position of overlap line, sharp corner ablation and remelting in multi-beam selective melting overlap forming, a trapezoidal interleave overlap strategy is presented here.The overlap strategy adopts trapezoidal interleave overlap lines to eliminate sharp corner ablation and makes the energy input of overlap region more uniform; and the overlap interfaces between adjacent layers are intertwined with each other, which can effectively improve the bonding degree between adjacent layers while ensuring the sufficient fusion of adjacent regions in a layer.Through the comparison of different overlap strategies, the proposed overlap strategy can reduce pore defects in the overlap region, enhance the microhardness of the overlap region, and improve the density and compressive strength of the formed samples.The tra-pezoidal interleave overlap strategy can effectively improve the quality of formed part overlap region and provide a new idea for additive manufacturing process of large-sized parts.

Key words： trapezoidal interleave overlap strategy contour separation multi-beam selective laser melting
