Abstract
Selective Laser Melting technologies have given a new boost to Rapid Tooling applications of Layer-Based Technologies, especially in plastic injection molding for prototype and pre-series tooling, but also for Conformal Cooling in production moulds. So far only very few and basic applications have become known for forming tooling like sheet metal forming, stamping or die forging. Market demands for "real forgings in a one week time" have lead to a case study with the goal to successfully produce forgings using a layer manufactured die. This paper presents this case study and its first results, compared to conventional tooling. Derived from the experimental work this paper gives a prospective on expedient future applications of direct Rapid Tooling for die forging, using Laser Melting technologies.
