3D-Printing is used to generate complex net-shaped parts directly from CAD-data and high alloyed PM steel powders by the combination of ink jet printing and powder metallurgy. The printed green parts undergo a liquid phase sintering step to full density. Heat treatments like annealing, stress-annealing, tempering, or post-HIPing are possible in combination with the sintering and lead to properties simiiar compared to conventional powder technology. Net-shape components with densities up to 99.5%, hardness up to 64 HRC and dimensions of more than 150 mm have been produced using HS 6-5-2 and X190CrVMo20 tool steel powders. The 3D-Printing process with a build rate of several hundred ccm/h seems ideally suited for individual production or small series production in due time of difficult to machine PM materials without limitations concerning geometrical complexity. The examples investigated in the study show, that 3D-Printing is a viable part in the production route of complex tool parts. The results show that in 3D-Printing of high strength tools steels always a compromise between sinter density, properties, surface quality and shape retention has to be found. The formation of high amounts of liquid phase requires careful control of sintering temperature. A combination of solid phase sintering and stepwise increase in amount of liquid phase seems to be the right choice to get both, density shape and surface quality. Both material types require a very careful temperature control on sintering. Melt draining into lower areas of parts is a potential failure source for both materials, when densities are not sufficient during heating or if simply the part geometry fosters gravity gradients by high and narrow shapes. The two steels, chosen as example for the 3D-Printing and sintering to full density offer a potential for application in near-shape tool production. The surface quality of the parts, which is determined by particle size and the surface tension of the liquid-phase sintering material, makes secondary finishing operations at least of functional surfaces necessary.
