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: 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.

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 three-dimensional (3D) object comprises a plurality of layers representative of an additive manufacturing process, wherein each layer of the plurality of layers approximately has a first thickness. A first layer of the plurality of layers forms at least a portion of a first surface of the 3D object, the first layer comprising a support region and an overcure region, wherein the first layer approximately has the first thickness at the support region and a greater second thickness at the overcure region. A support mark is included at the support region, wherein the support mark is inset from a first surface profile of the 3D object defined by the overcure region.
