Sebastian-Paul Kopp: Spatially resolved powder deposition for 3D printing
Sebastian-Paul Kopp works on a new technique for powder deposition in laser-based additive manufacturing. Similar to the principle of a laser printer, a light-induced charge pattern on a photoconductive plate allows a spatially resolved distribution of polymer powder on the build platform. This reduces the amount of material needed and enables the fabrication of multi-material parts as well as a decrease of the layer thickness. He published his latest results in the paper “Expanding the Capabilities of Laser-based Powder Bed Fusion of Polymers through the use of Electrophotographic Powder Application.”
To increase the efficiency and reliability of the powder deposition, Sebastian simulated and successfully implemented a piezo-based vibration of the photoconductive plate. This work is presented in the publication “Targeted Vibration Excitation for Increasing the Powder Deposition Efficiency in Electrophotographic Powder Application for Laser-based Powder Bed Fusion of Polymers”.
