Abstract

A 3D printing device (100), comprising a melt extrusion module (102), a printing module (103), and a platform module (104). The melt extrusion module (102) comprises a processing chamber (121) consisting of a feed inlet (124) and a discharge outlet (125), as well as an extrusion means (122) and a heating means (123) disposed at the processing chamber; the melt extrusion module (102) is configured to receive an initial material from the feed inlet (124) of the processing chamber (121), and heat and extrude the initial material to convert the initial material into a molten body, which is extruded out of the discharge outlet (125) of the processing chamber (121). The printing module (103) is communicated with the discharge outlet (125) of the processing chamber (121) and is provided with a nozzle (131); the printing module (103) is configured to receive the molten body extruded from the discharge outlet (125) of the processing chamber (121) and guide the molten body to be extruded out of the nozzle (131). The platform module (104) is configured to receive the molten body extruded from the nozzle (131).
