Problems solved by technology

[0003] However, the existing 3D printers are prone to plugging and broken joints of raw materials. The reason is insufficient heat dissipation. The existing printer heat dissipation devices cannot effectively use wind power to make greater contributions to 3D printing. Some printer nozzles have complex structure, poor durability and high cost, so they are not suitable for the general public.

Abstract

The invention discloses a 3D printing nozzle structure. The 3D printing nozzle structure comprises a polyether-ether-ketone shell, a polytetrafluoroethylene pipe, a venturi pipe, a nozzle body, a heating tip and a radiator device. A feeding inlet is formed inside the top end of the polyether-ether-ketone shell. The first polytetrafluoroethylene pipe is arranged at the bottom of the feeding inlet.The venturi pipe is arranged at the bottom of the first polytetrafluoroethylene pipe. Trapezoid steel conductive to heat dissipation is arranged on the outer side of the venturi pipe. The heating tipis arranged at the bottom of the venturi pipe. The nozzle body is arranged inside the heating tip. A fixed shell is arranged on one side of the venturi pipe. A patch fan is arranged on one side of thefixed shell. Fixed rods are arranged on the periphery of the patch fan in a surrounding manner. A wind shield is arranged at the other ends of the fixed rods. The area of the wind shield keeps the same as that of the patch fan. According to the 3D printing nozzle structure, the direction of air outlet of the fan is improved, the damage caused by wind force to an unformed printed article can be reduced, and nozzle blocking and material outlet suspension of equipment are not prone to happening.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a 3D printing nozzle structure. Background technique [0002] 3D printer, also known as three-dimensional printer, is a kind of cumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file, using special wax, powdered metal or plastic and other bondable materials. Print layers of adhesive material to create three-dimensional objects. At this stage 3D printers are used to manufacture products. The technology of constructing objects by printing layer by layer. The principle of a 3D printer is to put data and raw materials into the 3D printer, and the machine will build the product layer by layer according to the program. [0003] However, the existing 3D printers are prone to plugging and broken joints of raw materials. The reason is insufficient heat dissipation. The existing printer heat dissipation devices cannot effec...
