Influence of the Printing Parameters on the Quality of Alumina Ceramics Shaped by UV-LCM Technology

摘要

The commercial alumina dispersion LithaLox HP500 from Lithoz (Austria) was 3D-shaped on a customized LCM device equipped with a light engine emitting at a wavelength of 365 nm and pixel size of 20 μm. The precision of the green part fabrication was measured using gear geometry and different exposure energies. The effect of the layer thickness on the shaping of the green bodies and the sintered ceramics was also evaluated. Additionally, the strength of parts fabricated using different layer thickness was tested in ball-on-three-balls testing and their fracture surfaces were analysed.
