Abstract:
A 3D printer has a dual stage structure and includes: a frame; an extrusion unit having a nozzle configured to extrude a raw material; a stacking base unit positioned under the extrusion unit and configured to receive the raw material on a surface thereof so that an object is formed in a layer-by-layer manner on the surface; and a cutting unit positioned between the stacking base unit and the extrusion unit and configured to grind or cut the object formed on the surface of the stacking base unit, wherein the frame is configured to be connected to outer sides of the stacking base unit, the extrusion unit, and the cutting unit, the stacking base unit and the cutting unit are configured to be vertically movable along the frame, and the nozzle is configured to be movable on a plane.

Claim (Index 1):
A 3D printer having a dual stage structure, the 3D printer comprising:\n an extrusion unit configured to extrude a raw material; a stacking base unit positioned under the extrusion unit and configured to receive the raw material on an upper surface thereof so that an object is formed in a layer-by-layer manner on the upper surface of the stacking base unit; a cutting unit between the stacking base unit and the extrusion unit and configured to grind or cut the object formed on the upper surface of the stacking base unit; and a frame positioned outside the extrusion unit, the cutting unit, and the stacking base unit, wherein a distance between the extrusion unit and the cutting unit and a distance between the cutting unit and the stacking base unit are variable relative to each other, wherein the frame extends vertically and is configured to be connected to one or more of the extrusion unit, the cutting unit, and the stacking base unit, the one or more of the extrusion unit, the cutting unit, and the stacking base unit are configured to vertically movable along the frame, wherein the frame comprises a plurality of vertically-extending main guide beams, the vertically-extending main guide beams are arranged in a tetragonal shape, the stacking base unit is configured to be connected to some of the vertically-extending main guide beams, the cutting unit is configured to be connected to the remaining ones of the vertically-extending main guide beams, and the stacking base unit and the cutting unit are configured to be vertically movable along the main guide rails.
