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 method of three-dimensional (3D) printing includes heating a photo-curable material and extruding the photo-curable material from a nozzle of a dispenser 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 onto the first layer according to the digital file or an additional digital file to cure a portion of the first layer, wherein the cured portion of the first layer has a second shape, wherein the second shape may comprise features that are smaller than the first shape. The light source is attached to the dispenser and is movable to adjust a direction of the light beam relative to the nozzle of the dispenser.

Abstract: The present disclosure provides methods, systems, devices, and kits for creating composite materials from a single resin, the composite materials having multiple continuous phases. The disclosure includes a process to three-dimensionally print objects (e.g., orthodontic appliances) with composite properties. In some aspects, the composite properties are formed from a single formulation with components that, when processed, have hard and soft continuous phases. In some aspects, the composite properties are formed by separately processing the hard phase components and the soft phase components. In some aspects, the composite materials and devices are three-dimensionally printed using the processed material.

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: This disclosure provides low-viscosity resins for producing polymers with properties suitable for use in various mechanical appliances, such as orthodontic appliances (e.g., aligners). The low-viscosity resins may be photo-curable and can be used with direct fabrication methods and equipment. In various embodiments, the polymeric materials produced from the low-viscosity resins described herein have high toughness while remaining resistant to stress relaxation. Low-viscosity, photo-curable resins described herein have reduced hydrogen bonding in comparison to traditional materials (e.g., materials having high urethane content) used in orthodontic appliances.
