Self-heat dissipation type material tray for 3D printing

Abstract

The invention discloses a self-heat dissipation type material tray for 3D printing. The material tray comprises a machine body, and a printing head arranged in the machine body. A supporting plate located below the printing head is arranged in the machine body, and a condensing pipe is embedded in the supporting plate; the part, located below the supporting plate, of the inner wall of the machinebody is rotatably connected with a rotating shaft, and the side wall of the rotating shaft is fixedly connected with a plurality of electromagnets in the circumferential direction of the rotating shaft equidistantly; and the magnetic line of force of each electromagnet is in the radial direction of the rotating shaft, and the outer end of each electromagnet is fixedly connected with cambered heat-conducting fins. According to the self-heat dissipation type material tray, the structure is arranged in a 3D printer, and no excessive space is occupied; in the using process, the rotating shaft is rotated intermittently, and does not make noise due to high-speed rotation; meanwhile, a motor is not required for driving the rotating shaft; in addition, the speed of the self-heat dissipation type material tray can be regulated according to the temperature of printed materials, so that the power utilization is more scientific, and the energy consumption is lower; and the self-heat dissipation type material tray meets the modern standards for environmental protection and energy saving more properly.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a material tray for self-radiating 3D printing. Background technique [0002] 3D printing is usually achieved using digital technology material printers. It is often used to make models in the fields of mold manufacturing and industrial design, and is gradually used in the direct manufacture of some products. There are already parts printed using this technology. [0003] The working principle of the existing 3D printer is to use the computer to model first, then input the information into the 3D printer, and let the printer spray molten material through the high-temperature nozzle to make a 3D model. Therefore, when the 3D printer is printing, the internal temperature is very high. High, need to use auxiliary cooling device. There are still some problems with the current cooling devices for 3D printers. Most of the traditional cooling devices are metal heat transfer and fa...

Problems solved by technology

There are still some problems with the current cooling devices for 3D printers. Most of the traditional cooling devices are metal heat transfer and fans are used to dissipate heat. The fan will start to work, which consumes too much energy; in addition, during use, the cooling fan produces a lot of noise, and at the same time, the inability to quickly cool and solidify the molten material ejected from the high-temperature nozzle is also the main factor affecting the efficiency of 3D printing. one of the reasons
