In some embodiments, a system includes a carrier film (260), a first blade (270A) configured to form a layer of resin on the carrier film, a second blade (270B) configured to prevent printed features from contacting the first blade, and a build platform (120), where a portion of the layer of resin is to be added to an object being formed on the build platform. In some embodiments, a system includes a build platform and one or more blades configured to provide layers of resin to form an object on the build platform, where at least a first blade is configured to vibrate to reduce viscosity of the layers of resin. In some embodiments, a system includes a partial enclosure (280) configured to hold resin, one or more structures configured to at least partially cover the resin to prevent evaporation, and a build platform configured to support an object being formed from the resin.
