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 build platform configured to support an object that is being formed from layers of resin. The system further includes one or more blades configured to provide the layers of resin to form the object on the build platform. At least a first blade of the one or more blades is configured to vibrate to reduce viscosity of the layers of resin.

Abstract: A method of three-dimensional (3D) printing includes heating a photo-curable material and extruding the photo-curable material from a nozzle 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.

Abstract: Provided herein are methods of obtaining good photocured-ink adhesion to low surface energy materials. The methods have greatly improved adhesion of photocured ink on low surface energy materials, including those that are subjected to high humidity or wet environments. The methods take into account the glass transition temperature (Tg) of the materials and the onset for the glass transition temperature, including ink applied to an exposed surface of the material at an elevated temperature that is close to the Tg of the material. The ink is allowed to sit briefly or soak, such as for more than 1 second, before the ink is cured. The ink may be photocured. Furthermore, the methods do not require solvents or surface treatment, including plasma or corona treatments, to obtain good ink adhesion.
