Laser sintering is a powder-based additive processing technology, that has significant potential to reach the status of an additive manufacturing technology. The process reliability and component quality depend, among other things, upon layer generation. The effects of parameters, which have yet to be examined, and their influence on obtainable packing densities are investigated in correlation with the surface roughness on a self-developed laser sintering machine at the department of Production Engineering at the University of Duisburg-Essen. In commercial lasers sintering systems, it is often the case that the rotation speed of the powder applicator is maintained at a fixed ratio in regard to the translation speed. In other cases, a fixed blade with a defined geometry is utilized as the powder applicator. The adjustable parameters of the commercial systems are usually very limited, which results in difficulties for user optimization in powder application and the resulting component properties. In a custom-built machine, the rotational and translational movements of the roller are decoupled; thus, allowing each movement to be independently operated. For comparability of both application systems, the roller can be replaced by a blade. Through this study, only the rotation speed of the roller varies, while the translation speed is set to the standard value of 127 mm/s. The results show a disproportional increase in packing density as a function of the resulting speed at the tangential surface of the coating system. In addition, a direct comparison between the two commercial coating systems emphasize their different potential for improvements. For comparison, a DTM 2500 (3D- Systems) is used, which is equipped with a counter rotating roller.
