Problems solved by technology

When designing the scales, it was designed under stable conditions in the laboratory, so it can only be used for some situations. Once the 3D printer works in an environment with no air circulation and high temperature, plugging will occur.

Abstract

The invention discloses a 3D printing nozzle base for a super-high-rise building wind tunnel test. The 3D printing nozzle base for the super-high-rise building wind tunnel test comprises a fixing plate, a plurality of first through holes are formed in the fixing plate, a square block is fixed at the lower end of the fixing plate, a horizontally-arranged square through hole is formed in the middleof a square block, a cooling box slidably connected with the square through hole is arranged in the square through hole, a second through hole is formed in the upper end of the square through hole, the second through hole is connected with a feeding port, the feeding port penetrates through the fixing plate and is fixed to the fixing plate, a first threaded hole is formed in the lower end of the square block, a third through hole communicating with the first threaded hole is formed in the lower end of the square through hole, a first chamfer is arranged at the joint of the third through hole and the first threaded hole, and a nozzle which is in threaded connection with the first threaded hole is arranged in the first threaded hole. According to the 3D printing nozzle base for the super-high-rise building wind tunnel test, the device and a printing material are cooled through two-time cooling, the replaceable nozzle is arranged, so that the multi-purpose performance of the device is enhanced, and replacement is convenient after the nozzle is damaged.

Description

Technical field: [0001] The invention relates to the technical field of 3D printer equipment, in particular to a 3D printing nozzle base for super high-rise building wind tunnel tests. Background technique: [0002] 3D printer nozzle cooling system is the core system of 3D printer. The heat dissipation system directly determines the printing accuracy of the 3D printer and the smoothness of the model surface. There are two main solutions for the heat dissipation system of the nozzle of the 3D printer on the market. One is to directly increase the heat dissipation scales and allow the heat dissipation aluminum block to perform passive heat dissipation. The defect of this method is very obvious. In the case of passive heat dissipation, the volume of the heat dissipation aluminum block must be increased to increase heat dissipation efficiency. However, 3D printers often have restrictions on the size of the heat dissipation system of the nozzle, and the scales of the heat diss...
