    2020-7-1 · In 2013, Wilkes et al. also employed the SLM process to create zirconia-alumina ceramic parts (41.5 wt.% zirconia, 58.5 wt.% alumina), in which the part was formed free of sintering process. Nearly 100% density was achieved, and the crack formation was avoided by preheating the material to a temperature of at least approximately 1600 °C.
