Fraunhofer

Fraunhofer IPK in Berlin is a leading institute in production science. We conduct applied research and development along the entire process chain of manufacturing companies. Our goal is a sustainable production – inventive, human-centered and resource-efficient. We support companies in exploiting the potential of new manufacturing methods, in particular additive manufacturing processes. Our interdisciplinary team specializes in metal AM processes, offering economical solutions for printing innovative materials, customized repair processes and shortened time-to-market. Our strength lies in our broad manufacturing know-how, specifically combining classic production processes, automation concepts, post processing and IoT systems with additive processes. For us, additive manufacturing is a crucial building block for solving current challenges in production.
