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: Embodiments relate to a pre-fabricated attachment for fabricating custom objects. In one embodiment, a system includes a mold and a pre-fabricated attachment. The mold includes a physical model of a dental arch of a patient and one or more first features. An orthodontic aligner is to be formed over the physical model. The pre-fabricated attachment includes one or more second features configured to removably attach to the one or more first features. The pre-fabricated attachment further includes a traceability component configured to be used to determine one or more identifiers corresponding to the mold. The pre-fabricated attachment further includes a handling component configured to be secured by a robot or person to transport the mold and pre-fabricated attachment during production of the orthodontic aligner. The pre-fabricated attachment may be reused.
