Abstract: A system includes a carrier film including an outer surface and an inner surface. The inner surface is configured to contact rollers. The system further includes a first blade configured to form a layer of resin on the outer surface of the carrier film. The system further includes a second blade configured to prevent printed features from contacting the first blade. The system further includes a build platform. A portion of the layer of resin is to be added to an object being formed on the build platform.

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.
