CERAMIC THREE-DIMENSIONAL PRINTING USING SELECTIVE CHEMICAL CURING

Document Type and Number:

WIPO Patent Application WO/2023/101424

Kind Code:

A1

Abstract:

According to one embodiment of the present invention, provided is a three-dimensional printing method comprising: a first step of applying a ceramic composition; a second step of spraying a reaction solution at at least a part of the applied ceramic composition; and a third step of irradiating the applied ceramic composition with energy so as to cure, through a chemical reaction, the region at which the reaction solution has been sprayed, thereby forming a ceramic layer, wherein at least one cycle of the first to third steps is repeatedly performed on the ceramic layer, and the remaining part, excluding the part cured through the chemical reaction, is removed so as to form a three-dimensional structure.
