Researchers from the Institut für Integrierte Produktion Hannover and Laser Zentrum Hannover have begun work that seeks to enable laser welding of 3D-printed components. The project, titled QualLa (Quality assurance in laser welding of additively manufactured thermoplastic components), aims to develop an expert system that supports small- and medium-size businesses in optimizing additive manufacturing processes so that the printed components may be welded using lasers.
Laser welding is an established joining process for injection-molded plastic components. With 3D-printed components, however, uniformity in internal structure presents problems. Even with components from the same series that appear identical from the outside,…READ MORE
