Using Additive Manufacturing ("3D Printing") it is possible to produce parts of almost any shape without the need for tools. Its major advantages are the fast availability of functional products and small series, the possibility to individualize products and the ability to quickly produce parts anywhere in the world without transportation costs. To this end, CAD files are processed into layer files, from which parts are built layer by layer.
Within the Direct Manufacturing Research Center (DMRC), the Particle Technology Group examines the polymer laser sintering. In this method, thin layers of polymer powder are preheated and then selectively melted by a laser. Although this process is already used in industrial production, there is still a need for research to further process know-how, reproducibility and to enable new applications. The current projects are described below.
