ABSTRACT: Laser Beam Melting (LBM) represents an additive process where metallic components are generated layer-wise. A laser beam operates as heat source melting metal powder. The temperature level in the heat affected zone is considered as a critical issue and can be influenced by many parameters, e.g. the laser power and the scanning velocity. Temperature levels out of a reliable range. Introduction. Powder bed fusion (PBF) is one of the most mature and widely used additive manufacturing (AM) process, during which the powdered material is selectively consolidated by melting using a heat source such as laser [] or electron beam [Reference Wang and Chou 2].As one of the typical PBF-AM process, the laser PBF-AM process, also named as selective laser melting (SLM) or direct.
