Technology alert: Fraunhofer Institute for Laser Technology researchers are implementing stereolithography and multi-photon polymerization technologies in one machine. Fraunhofer Institute for Laser Technology ILT is a research institute based in Aachen, Germany. Its researchers are working on a project called: “High Productivity and Detail in Additive Manufacturing through the Combination of UV Polymerization and Multi-Photon Polymerization” or HoPro-3D. The idea is to build a 3D printer which is both fast and precise by combining stereolithography and multi-photon polymerization technologies and having two systems in one machine. “The advantage lies in the interplay between the two procedures: Depending on the need, we intend to switch between the exposure systems in the process,” explains Dr. Martin Wehner, HoPro-3D project manager at Fraunhofer ILT. “The challenge we face is in process control. The concept has been developed, currently, an appropriate machine is being built.” As well as producing the […]
