Abstract
Apparatuses and methods for producing three-dimensional objects are disclosed. In an embodiment, an apparatus for solid freeform fabrication comprises a movable nozzle comprising a nozzle opening, a heating element connected to the movable nozzle, a driver connected to the movable nozzle, a platform for receiving a build material from the movable nozzle, and a hopper for providing the build material to the driver, the hopper comprising a hopper opening, wherein the nozzle opening and the hopper opening are capable of simultaneous alignment on a straight axis such that the build material, when present, is capable of traveling along the straight axis at least from the hopper opening until the build material attains a flowable state.
