Additive manufacturing of production tools through laser-based powder bed fusion is at the focus of this presentation. Design and manufacturing of production tools & dies for stamping of sheet metal parts, cores (inserts) for injection moulding of plastic components and other types of production tools are addressed. Solid and topology optimized tools are tested, compared with the conventionally designed and manufactured version of the same tools, and certified. The current possibilities and constraints are addressed from the material, technological and business perspectives. The current manufacturing readiness level and the industrialization status of metal additive manufacturing through laser-based powder bed fusion are evaluated.
