Abstract

The paper proposes the design of a 3D printer that prints with a wax slip based on corundum powders. To activate the sintering of ceramics, the corundum grains are preliminarily clad with a two-layer shell of manganese and titanium compounds Al2O3–MnAl2O4–TiO2, which allows reducing the sintering temperature to 1400°C compared to pure corundum and ensures an even distribution of the sintering additive.
