Heat preservation 3D printer

Abstract

The invention discloses a heat preservation 3D printer which comprises a printing mechanism, an electrical device and a shell. An electrical bin and a printing bin are arranged in the shell, a first air inlet is formed in the side face of the electrical bin, a first fan is arranged in the electrical bin, and a ventilation opening is formed in the side face of the printing bin. A third fan, a heating device and a first temperature sensor are arranged at the position close to the ventilation opening. According to the heat preservation 3D printer, the printing mechanism and the electrical device are arranged in the printing bin and the electrical bin correspondingly, the first fan introduces external air into the electrical bin through the first air inlet, airflow is formed, the third fan can introduce the airflow into the printing bin through the ventilation opening, and the first temperature sensor detects the temperature of gas entering the printing bin. And the heating device heats the gas according to the detected temperature value, so that the gas flow temperature is approximately stabilized at the proper working temperature of a printing product of the printing mechanism, heat preservation is conducted on the printing bin, the printing mechanism works at the proper temperature, and the 3D printer is used for the field of 3D printing.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a thermal insulation 3D printer. Background technique [0002] The working principle of light-curing 3D printing is: the light of specific wavelength and intensity is irradiated to the molding interface filled with photosensitive resin, so that the photosensitive resin in the molding interface is cured to form a layer of printing sheet, and the first layer is printed; After the resin refills the molding interface again, it continues to solidify and form another layer of printed sheet on the basis of the printed sheet, and so on and forth, superimposed and cured layer by layer, and finally forms an entity. [0003] During the photocuring 3D printing process, the temperature will affect the fluidity of the photosensitive resin, which in turn will affect the speed at which the photosensitive resin reflows to fill the molding interface. When the reflow speed of the photosensitive resin is ...

AI Technical Summary

Problems solved by technology

[0003] During the photocuring 3D printing process, the temperature will affect the fluidity of the photosensitive resin, which in turn will affect the speed at which the photosensitive resin reflows to fill the molding interface. When the reflow speed of the photosensitive resin is too slow, it will not only prolong the printing time, but also affect the surface of the printed part. quality

Existing light-curing 3D printers generally perform 3D printing at room temperature. For 3D printing products that require high precision and require mass production, temperature changes will affect the printing efficiency and printing accuracy of the product.
