Additive Herstellung mehrkomponentiger metallischer und keramischer Bauteile mittels thermoplastischen 3D-Druckes (T3DP)

Additive manufactoring (AM) allows the designing of the components oriented to function instead to fabrication. Thus, the possibility for further functionalization and miniaturization is provided. By the combination of different materials in one single AM component the number of degrees of freedom can be increased even further. T3DP allows both: the additive processing of metallic, as well as of ceramic suspensions. Due to the adjustment of the shrinkage behavior of the specific suspensions, the co-sintering of multi-material components is possible. Combining materials like zirconia and stainless steel allow certain property adjustments e.g. electrical and thermal conductivity or non-conductivity, brittleness and ductility. The developed suspensions show a thermalplastic behavior. At processing temperatures of around 100°C low viscosities at high solid loadings up to 67 vol-% were realized. In that way, both the desposition of filaments and individual droplets is possible
