Abstract

The MoldJet process is a new and innovative, sinter-based additive manufacturing process that combines two generative process steps. This synergy enables an enormous variety of shapes from small filigree to large-volume 3D-printed metal parts. Many comparable AM processes specialise in just one spectrum of geometries or are limited by the printing process and following process steps. The MoldJet process offers the possibility of producing different component geometries not only simultaneously, but also without the use of support structures made of part material. In this paper, the application range of the process is presented. On the basis of evaluation geometries, it is analysed where the minimum for wall thicknesses at the printing process lies. On the other hand, component geometries with large external dimensions on the one hand and large-volume component areas on the other hand are produced and limitations with regard to the printing process are also determined here.
