Abstract: A 3D printer comprises a platform, a dispenser, and a light source. The dispenser comprises a nozzle to extrude photo-curable material onto the platform to form a first layer according to one or more digital files. The first shape of the one or more extruded photo-curable materials corresponds to a first minimum line width that is based on a diameter of the nozzle. The light source is to emit a light beam directed onto the first layer according to the one or more digital files to cure a portion of the first layer. A first cured layer of the one or more photo-curable materials corresponds to a second shape of a first layer of a 3D printed orthodontic aligner specified by the one or more digital files. The second shape has a second minimum line width that is smaller than the first minimum line width.

Abstract: A method of manufacturing a three-dimensional (3D) object may include fabricating a support structure and fabricating the 3D object on the support structure, wherein the support structure contacts the 3D object at a support region of the 3D object. The method further includes overcuring the 3D object at an overcure region of the 3D object, wherein the overcure region is distinct from the support region, and removing the support structure from the 3D object. After removal of the support structure, a support mark remains on the 3D printed object where the support structure had contacted the 3D object, wherein the overcure region of the 3D object projects past the support mark.

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.

Abstract: A system includes a mold of a dental arch of a patient. The mold includes teeth extending from a first distal end of the dental arch to a second distal end of the dental arch. An orthodontic aligner is to be formed over the teeth of the mold. The teeth of the mold are shaped to correspond to tooth-receiving cavities of the orthodontic aligner. The system includes a pre-fabricated attachment that 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 the pre-fabricated attachment during production of the orthodontic aligner.

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.
