Efficient heat dissipating and blockage preventing 3D printing nozzle

Abstract

The invention provides an efficient heat dissipating and blockage preventing 3D printing nozzle. The 3D printing nozzle comprises a heating mechanism; a nozzle module and a heating module are arranged in the heating mechanism; the heating mechanism is connected with a cylindrical heat dissipating mechanism; a thermal insulating mechanism is arranged between the heating mechanism and the heat dissipating mechanism, and is communicated with the nozzle module and the heat dissipating mechanism; the heat dissipating mechanism includes a cylindrical heat dissipating pipe; multiple heat dissipating pieces are uniformly arranged on the outer wall of the heat dissipating pipe; a small pipe is inserted in the heat dissipating pipe, and is screwed with the heat dissipating pipe; a clamping port is formed in one end, far from the small pipe, of the heat dissipating pipe; the connected places of the clamping port and the end part of the heat dissipating pipe form a shrinking port; and one end of a guide pipe is inserted in the small pipe, and the other end is inserted in the heat dissipating pipe to bond with the shrinking port. The efficient heat dissipating and blockage preventing 3D printing nozzle solves such technical problems as high energy consumption, low nozzle wire discharge effici8ency, easiness in nozzle blockage and difficult consumable extrusion in the prior art.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a high-efficiency heat dissipation and anti-clogging 3D printing nozzle. Background technique [0002] 3D printer is a digital model file-based technology that uses bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. In the past, it was often used to make models in the fields of mold manufacturing and industrial design, and is now gradually being used in the direct manufacture of some products. [0003] In 3D printing, software completes a series of digital slices through computer-aided design (CAD) and sends information about those slices to a 3D printer, which stacks successive thin layers until a solid object is formed. There are various forms of stacking thin layers. Some 3D printers use an "inkjet" method. For example, an Israeli 3D printer company called Objet uses a printer nozzle to spray an extremely th...
