摘要:
An additive manufacturing apparatus includes: a build table, at least a portion of which is transparent, the build table defining a build surface; a material applicator operable to deposit a radio-energy-curable resin on the build surface; a stage positioned facing the build surface of the build table and configured to hold a one or more cured layers of the resin; one or more actuators operable to change the relative positions of the build table and the stage; a radiant energy apparatus positioned adjacent to the build table opposite to the stage, and operable to generate and project radiant energy on the resin through the build table in a predetermined pattern; a drive mechanism operable to move the build table so as to expose a new portion thereof for each layer; and material remover operable to remove remnants from the build surface. A method for using the apparatus is provided.
