Abstract: A three-dimensional printing apparatus includes a container and a projecting structure. The container is configured to contain a liquid photosensitive material. The projecting structure is configured to provide a variety of molding beams to irradiate the liquid photosensitive material. The photoinitiator is suitable for polymerizing with a monomer after receiving the first molding beam with the first wavelength to form a solidified layer with a first color, and the photoinitiator is suitable for polymerizing with the monomer after receiving the second molding beam with the second wavelength to form a solidified layer with a second color, wherein the first color is different from the second color. The projecting structure comprises a light combiner module, disposed on the transmission paths of a variety of light beams. The wavelengths of the first molding beam and the second molding beam are between 355 nm to 415 nm.

Abstract: A three-dimensional printing apparatus includes a container and a projecting structure. The container is configured to contain a liquid photosensitive material. The liquid photosensitive material includes a variety of photoinitiators and a monomer. The projecting structure is configured to provide a variety of molding beams to irradiate the liquid photosensitive material. The variety of molding beams have different wavelengths and are used to actuate a polymerization between one of the variety of photoinitiators and the monomer respectively thereby forming a solidified layer. A three-dimensional printing method is also provided.
