3D print heads for use in 3D printers, 3D printers with such 3D print heads, methods of operating such 3D printers, and printing products made with such 3D printers

摘要

The 3D printer head includes a chamber configured to receive liquid or solid printing material through the inlet. The chamber has an outlet opening on one surface, the helical feed screw associated with the chamber, the helical feed screw rotating the helical feed screw or chamber in such a way that the helical feed screw rotates relative to the chamber at a distance from the surface of the chamber. And by coupling the drive configured to the spiral feed screw or chamber, the printing material passing from the inlet into the chamber is configured to supply to the outlet opening. The spiral feed screw includes at least one conveyor configured to convey printing material toward the outlet region between the inlet region located radially outward and the outlet region located radially inward, and the radially outer boundary region of the outlet region. And at least one discharge conveyor arranged and configured to convey the print material with the gas present therein to be spaced apart from at least one section of the device.
