Abstract
A new process, staggered stacking method of printing wires and printing wire deformation by 3D gel-printing, to prepare ZrO2 dense parts was used in this study. In order to reduce the gap between adjacent printing wires, a new type of stacking method-staggered stacking is proposed. The density of sintered parts prepared by staggered stacking method is about 88%. In order to eliminate the gap between the adjacent cylindrical printing lines, according to printing wire deformation and then adjusting the parameters, the printing head was used as a scraper to fill the gaps. The relative density of sintered body prepared by staggered stacking method of printing wires and printing wire deformation in this study is 98.86%, and the three-point bending strength of the parts is 496 ± 20 MPa.
