摘要
In metal additive manufacturing(AM),processing parameters can affect the probability of macroscopic defect formation(lack-of-fusion,keyholing,balling),which can,in turn,jeopardize the final product’s integrity.A printability map classifies regions in the processing space where an alloy can be printed with or without porosity defects.However,the creation of these printability maps is resource-intensive.Previous efforts to generate printability maps have required single-track experiments on pre-alloyed powder,limiting the utilization of these printability maps for the high-throughput design of printable alloys.
