Abstract

The invention relates to the use of SiC particles (grains) in a 3D print method for providing a SiC ceramic preform (green body), wherein the SiC particles (grains) are characterized by - an average grain size (d<50>) of 2 to 70 µm, preferably 3 to 65 µm, more preferably 5 to 50 µm, such as 25 to 60 µm, preferably 40 to 55 µm, - a roundness of > 0.55, preferably > 0.58, more preferably > 0.6 (as described in experimental section , - bulk density of > 1.6 g/cm<3>, preferably > 1.65 g/cm<3>, more preferably > 1.7 g/cm<3>, even more preferably > 1.75 g/cm<3> (according to DIN EN 725-9 ISO 23145-2).
