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 automating removal of an untrimmed shell (150) from a mold (140). In one embodiment, a shell removal device includes a body and a platform (120) disposed within the body (110). The platform is configured to secure a mold that has an untrimmed shell formed over the mold. The shell removal device further includes a cover (130A) configured to secure the untrimmed shell to an upper surface of one or more sidewalls of the body and provide a seal between a lower surface of the untrimmed shell and the upper surface of the one or more sidewalls of the body. The shell removal device may include a media inlet (116) in the body (110) to permit pressurized media into the interior (114) of the body to cause a pressure differential between an upper surface of the untrimmed shell and the lower surface of the untrimmed shell to cause the untrimmed shell to release from the mold.

Abstract: A method of three-dimensional (3D) printing includes heating a photo-curable material and extruding the photo-curable material from a nozzle (218) to form a first layer of an object according to a digital file, wherein the first layer has a first shape specified by the digital file, and wherein the first shape has a first minimum line width based on a diameter of the nozzle. The method further includes directing a light beam (315) onto the first layer according to the digital file or an additional digital file to cure a portion of the first layer (310), wherein the cured portion (310) of the first layer has a second shape, wherein the second shape may comprise features that are smaller than the first shape.

Abstract: A method includes identifying first geometry of a first mold associated with a first dental arch and a second geometry of a second mold associated with a second dental arch. The method further includes determining, based on the first geometry and the second geometry that the first mold and the second mold are to be used for simultaneous forming of a first dental appliance and a second dental appliance on a plate in a dental appliance manufacturing system. The method further includes causing, based on the first geometry and the second geometry, one or more portions of the dental appliance manufacturing system to be configured to form the first dental appliance and the second dental appliance.
