Abstract:

The work deals with the printing of porous, metallic structures using the MoldJet technology. The MoldJet process is a novel, sinter-based additive manufacturing process, which enables the produc-tion of a wide range of geometries, ranging from small filigree to large-volume metal components without the need of support structures. The high productivity of up to 1600 cm³/h also enables series production of components. These process advantages are now to be exploited in the manufacture of porous structures. The technical limits in terms of porosity, pore size and design freedom are exam-ined. In particular, the different requirements for the component design will be illuminated. Based on different test geometries, the basic possibilities for the production of porous structures using MoldJet are to be demonstrated in an initial study.
