About us

Manufacturing technologies have a new colleague. Regarded for a long time as a pure prototyping approach, AM technology has now achieved series-production readiness. Often over-simplified as a kind of 3D printing, AM technologies are key drivers that can open up new market opportunities for machine suppliers, manufacturing service providers and designers/OEMs. And as machines, materials, and software solutions become more available, their implementation will extend into new process chains with impressive business innovations. In this context the ACAM Aachen Center for Additive Manufacturing was founded as a platform for networking, coordinating joint research and development as well as conducting training and education seminars.
