Abstract [en]

Being a fast, powerful and crack-free manufacturing process, electron beam melting (EBM) has been gaining importance for tooling industry for the recent years. EBM allows processing high melting materials under vacuum atmosphere with high building rates, which offers less residual stresses caused by the complex thermal history and high cooling rates during the manufacturing. Uddeholms AB has previously shown on a pilot scale the performance capabilities of the EBM process in respect to the high alloyed and commercially available tool steel powder grade Vanadis® 4 Extra AM. In this study, industrial scale demonstrators and application tools were produced from Vanadis® 4 Extra AM powder. Industrialization of the concept studies was completed. Verification of the parts were conducted by using a slider-on-flat-surface (SOFS) wear tester and a semi-industrial punching test. Moreover, the dimensional tolerances, need of post processing treatments and product qualities were emphasized within the scope of this investigation. © European Powder Metallurgy Association (EPMA)
