Abstract

The invention discloses a heat sink for a FDM type 3D printer. The heat sink comprises a pressure air flow generating device, a pressure air flow conveying pipeline and a 3D printing head shell, wherein the pressure air flow conveying pipeline is connected with the pressure air flow generating device and the 3D printing head shell; the pressure air flow generating device is provided with a pressure air flow generator, an air flow guiding member and a pneumatic quick connector at an outlet; the pressure air flow generator is connected with the quick connector through the air flow guiding member; the quick connector is connected with the 3D printing head shell through the pressure air flow conveying pipe; and air ducts are arranged on both sides of the 3D printing head shell. According to the heat sink for the FDM type 3D printer, the pressure air flow generating device uses a turbocharging fan to generate air flow with pressure, and the generated pressure air flow is delivered to the inside of the printing head shell through the pressure air flow conveying pipeline so as to realize heat dissipation of a 3D printing head; the volume of the heat-dissipation air flow is large and the speed of the air flow is fast; and the inclined air ducts are distributed on both sides of the 3D printing head shell and divert the pressure air flow, so the flowing direction and heat dissipation area of the pressure air flow are optimized and heat dissipation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a heat dissipation device of an FDM type 3D printer. Background technique [0002] At present, the desktop 3D printers on the market are basically FDM-based. The main advantages of this technology are simple structure and low cost. The consumables are sent to the heating block above the nozzle through the feeding mechanism, and the consumables are melted in the heating block and extruded by the nozzle. At the same time, the nozzle moves according to the contour of the layered model, and the extruded molten consumables are cooled and solidified by the fan to complete the printing of one layer of the 3D model, and then the printing platform is lowered for the next layer of printing, and finally the layers of consumables stick to the One of the development directions of FDM-type 3D printers is ultra-high-speed printing, and one of the factors restricting its development to ult...
