In commercial Selective Laser Melting (SLM) machines, the removal of spatter particles and other undesired by-products is performed by pumping inert gas unidirectionally over the powder bed. However, traces of deposited spatter which are darker in contrast as compared to the fresh powder are often observed during the SLM process. The effectiveness of the inert gas flow in transporting spatter particles was identified as a critical hindrance in the expansion of the powder bed area. With respect to the SLM machines produced by SLM Solutions Group AG (Lubeck, Germany), the powder bed width for all the current machine variants is limited to 280 mm along the x axis. In this thesis, studies on the effects of spatter particles, their distribution ...
