abstract = {High efficiency in terms of powder consumption and the ability to generate multi-material parts using additive manufacturing are key features of the electrophotographic powder application for laser-based powder bed fusion of polymers (PBF-LB/P). The reliable deposition of powder particles onto the build platform is one decisive process step. The aim is to achieve a high degree of coverage and, at the same time, maintain an accurate contour of the deposited powder layer.
In addition to the use of a suitable electrical transfer field, which has already been investigated, targeted vibration excitation offers enormous potential for improvement. For this purpose, a mechanical simulation model is set up in this study, which is subsequently validated experimentally. By using the knowledge gained from the simulation, for example with regard to suitable vibration modes, the powder deposition has been significantly improved.
