Abstract: A method of 3D printing comprises extruding one or more photo-curable materials from a nozzle to form a first layer that has a first shape specified by the one or more digital files, wherein the first shape corresponds to a first minimum line width that is based on, and narrower than, a diameter of the nozzle. The method further includes directing a light beam onto the first layer according to the one or more digital files to cure a portion of the first layer to create a first cured layer, wherein the first cured layer corresponds to a second shape of a first layer of a 3D printed orthodontic aligner, wherein the light beam has a beam diameter that is smaller than the diameter of the nozzle, and wherein the second shape has a second minimum line width that is smaller than the first minimum line width.

Abstract: A 3D printer comprises a platform, a dispenser and a light source. A heating element heats a material and a nozzle extrudes the heated material onto the platform to form a first layer, having a first shape specified by one or more digital files. The first shape corresponds to a first minimum line width based on a diameter of the nozzle. The light source emits a light beam that is directed onto the first layer according to the one or more digital files to cure a portion of the first layer to create a first cured layer that corresponds to a second shape of a 3D object specified by the one or more digital files. The light beam has a beam diameter that is smaller than the diameter of the nozzle, and the second shape has a second minimum line width that is smaller than the first minimum line width.
