3D-Printing with the Paste Based on Corundum Powders’ Core Shell

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 Al 2 O 3 –MnAl 2 O 4 –TiO 2 , which allows reducing the si...

Summary: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 Al 2 O 3 –MnAl 2 O 4 –TiO 2 , which allows reducing the sintering temperature to 1400°C compared to pure corundum and ensures an even distribution of the sintering additive.
