Selective laser melting (SLM) is a powder-bed-fusion AM process whereby a high-density-focused laser beam selectively scans a powder bed and those scanned and solidified layers are stacked upon each other to build a fully functional three-dimensional part, tool, or prototype [1]. ...
Also, defect formation is a common problem in selective laser melting (SLM) process. Because of that, in the paper of B. Zhang, Y. Li, and Q. Bai was discussed the effect of the process parameters on defect formation and the impact of defect formation on the mechanical properties of a...
Abstract This paper discusses the principle and the relevance of an in situ monitoring system for selective laser melting (SLM). This system enables the operator to monitor the quality of the SLM job on-line and estimate the quality of the part accordingly. The monitoring system consists of two...
