Problems solved by technology

[0005] However, there is a problem in the printing process of such a 3D printer. After the photosensitive resin material is treated with light, it will produce exhaust gas with a pungent smell. After the human body is in such an environment for a long time, it will inevitably have a negative impact on human health.

Embodiment Construction

[0030] Such as Figure 1 to Figure 4 As shown, the DLP three-dimensional printer of this embodiment includes a frame 10 , a projector light source, a photosensitive resin tank 20 , a printing platform 30 , a screw drive mechanism 40 , a control system and an exhaust gas cleaning device 50 . The photosensitive resin tank 20 is filled with photosensitive resin for light curing and molding. The photosensitive resin tank 20 is arranged in the frame 10. Driven by the screw drive mechanism 40, the printing platform 30 can move in the photosensitive resin tank 20. The printing platform 30 Used to carry three-dimensional objects. The frame 10 forms a closed chamber, so that the light-curing molding process of the photosensitive resin can be placed in a closed environment, and to a certain extent, the irritating exhaust gas generated during the curing process of the photosensitive resin can be prevented from diffusing into the surrounding environment.

Abstract

The invention relates to a DLP three-dimensional printing device and a forming method thereof. The printing device comprises a photosensitive resin tank used for containing photosensitive resin which is used for curing forming of three-dimensional objects, and a printing platform used for holding the three-dimensional objects and capable of moving in the photosensitive resin tank. The photosensitive resin tank is formed in a closed chamber. The DLP three-dimensional printing device further comprises a waste gas cleaning device. The waste gas cleaning device communicates with the closed chamber and is provided with a negative pressure generator. The negative pressure generator is used for collecting waste gases produced in curing forming of the photosensitive resin. A printing method comprises the steps of forming, waste gas collection and waste gas processing. Due to the collection effect on the waste gases, harm to the human body due to improper waste gas processing is reduced and meanwhile the environmental protection is facilitated.

Description

technical field [0001] The invention relates to the field of three-dimensional printing, in particular to a digital light processing (DLP) three-dimensional printer. Background technique [0002] Three-dimensional (3D) printing is based on a three-dimensional design model, through software layering and numerical control molding, and then using laser beams, hot-melt nozzles, light curing and other methods to pass metal powder, ceramic powder, plastic, photosensitive resin and other materials through layer by layer The technique of stacking and forming by stacking and bonding finally produces a physical product. [0003] The working principle of the digital light processing (DLP) light-curing 3D printer is to use DLP technology, the light source is imaged by a projector, and the light source solidifies the liquid photosensitive resin layer by layer, and prints out a 3D object with a higher resolution than typical fusion deposition. Manufacturing (FDM) type 3D printers. [00...
