Theoretical Study on Overlapping Mechanism in SLM Based on Interlayer-staggered Scan Strategy

摘要：

　　In the study of the overlapping mechanism in selective laser melting (SLM) process based on interlayer-staggered scan strategy,relationship between the intra-layer overlapping rate and the inter-layer overlapping rate was obtained by theoretical deduction based on the continuity of layers; the overlapping mechanism and the depositing efficiency were later analyzed.Results showed that three types of overlapping mechanism exist under different values of overlapping rate:the intra-layer overlapping mechanism,the inter-layer overlapping mechanism and the mixed overlapping mechanism with coexistence of the first two types; the maximal depositing efficiency of intra-layer overlapping mechanism and inter-layer overlapping mechanism is 0.38 and 0.5 respectively.This study has provided basic theory for improving depositing efficiency in SLM process.
