Abstract:
Techniques, systems, and devices are described for implementing a portable and affordable 3D printer. One portable 3D printer includes a material supply system to supply printing material to a print engine. The print engine includes an extrusion system that comprises a heating block, which includes a top portion coupled to the material supply system to receive the printing material, a heating body to heat up the printing material, and a heat break portion positioned between the top portion and the heating body. The printer further includes a movement system to allow a horizontal movement of the extruder carriage, a build platform positioned below the movement system to receive the printing material from the extrusion system, and a printer body positioned to enclose the extrusion system, the movement system, and the build platform.

Claim (Index 1):
A portable three-dimensional (3D) printer, comprising:\n a material supply system including a spool or a cartridge to supply printing material to a print engine; the print engine including an extrusion system that comprises a heating block, the heating block including:\n a top portion coupled to the material supply system to receive the printing material, \n a heating body positioned below the top portion, wherein the heating body is coupled to a heating element operable to supply heat to the heating body and heat up the printing material, the heating body further coupled to a temperature sensor operable to sense a temperature of the heating body, and \n a heat break portion positioned between the top portion and the heating body, the heat break portion having a first end in contact with the top portion, a second end in contact with the heating body, and a center, wherein each end has a larger cross-sectional area than a cross-sectional area of the center to reduce heat transfer from the heating body to other components of the 3D printer; \n a movement system that comprises:\n an extruder carriage positioned to carry the extrusion system, \n multiple pulleys, each positioned to rotate around a vertical axis, wherein at least two of the multiple pulleys are stacked on top of one another to allow a compact design of the movement system, and \n one or more belts in contact with each of the multiple pulleys and with the extruder carriage to allow a horizontal movement of the extruder carriage; \n a build platform positioned below the movement system to receive the printing material from the extrusion system; and a printer body that encloses the extrusion system, the movement system, and the build platform, wherein the printer body includes an aperture to allow access to an internal space of the 3D printer.
