Fanless cooling device for 3d printers and fdm high-speed 3d printers

Abstract

The invention relates to a fanless cooling device applied to a 3D printer and a fused deposition molding high-speed 3D printer with the fanless cooling device, belonging to the technical field of 3D printing. The fanless cooling device of this invention includes an air outlet and an air pump connected to the air outlet, without a fan, and the air outlet is arranged near the extrusion nozzle of the 3D printer, so it can effectively avoid damage caused by the rotation of the fan. The vibration problem of the extrusion nozzle. At the same time, since the annular body of the air outlet is arranged around the extrusion nozzle, and its air outlet is located on one side facing the extrusion direction, it will not cause uneven extrusion of the material caused by the cooling of the extrusion nozzle. Therefore, the accuracy of 3D printing can be effectively improved. The fanless cooling device for 3D printers and the fused deposition molding high-speed 3D printer with the fanless cooling device of the present invention have a simple structure and low cost.

Description

technical field [0001] The present invention relates to the technical field of 3D printing, in particular to the structural technical field of 3D printers, and specifically refers to a fanless cooling device applied to 3D printers and a fused deposition molding high-speed 3D printer. Background technique [0002] In the field of 3D printing technology, after the extrusion equipment extrudes the printing material according to the printing needs, the printing material needs to be cooled rapidly so that the shape can be fixed as soon as possible to meet the printing needs. Existing 3D printers generally use cooling fans, which have a better cooling effect and have a wide range of applications. [0003] However, during the rotation of the cooling fan, it is easy to cause the extrusion nozzle to vibrate, which will cause ripples on the surface of the printed model, which will affect the printing accuracy. At the same time, the fan’s air supply range is too large, which will also ...

Problems solved by technology

[0003] However, during the rotation of the cooling fan, it is easy to cause the extrusion nozzle to vibrate, which will cause ripples on the surface of the printed model, which will affect the printing accuracy. At the same time, the fan’s air supply range is too large, which will also cause the extrusion nozzle to cool down and cause uneven material extrusion. problems, which will adversely affect the final printing effect
