3D printing ink composition comprising ultraviolet absorber and manufacturing method thereof and 3D printing method

摘要

A three-dimensional printing method is provided. The three-dimensional printing method is a method of preparing an ink composition comprising ceramic particles, a surface modifier, a photocuring agent, an ultraviolet absorber, and a photoinitiator, placing the ink composition in a container and irradiating light to the ink composition, Curing the ink composition on the top of the container to prepare a three-dimensional printing molded layer, and repeatedly performing the three-dimensional printing molded layer manufacturing step to prepare a three-dimensional printing molded body in which the three-dimensional printing molded layer is stacked. It may include steps.
