Problems solved by technology

When the 3D printing device with this structure is solidified, because there is no obstruction on the upper surface of the solidified layer, it is easy to have a bulge in the middle due to the surface tension of the solidified layer, which in turn affects the printing quality of the 3D object.
[0003] In addition, the current common 3D printing devices are small, and the printing size is generally 100~600*100~600*200~450mm

Abstract

The invention discloses a 3D printing device and a printing method thereof. The 3D printing device comprises a base, a printing mechanism, a scraper mechanism, an exposure mechanism and a control mechanism, wherein a solution tank used for containing a printing solution is installed in the base; the printing mechanism comprises a module and a printing platform slidably installed on the module; the scraper mechanism comprises guide rails arranged on the two sides of the solution tank, and a scraper slidably installed on the guide rails; the exposure mechanism comprises a projector and a movement assembly driving the projector to move above the solution tank, and an exposure opening of the projector directly faces the printing platform during exposure; and the control mechanism is electrically connected with the printing mechanism, the scraper mechanism and the exposure mechanism and used for controlling the action of all the mechanisms. According to the 3D printing device and the printing method thereof, large 3D articles can be printed; and the 3D printing device and the printing method thereof have the characteristics of being high in printing precision, high in speed, easy to operate and the like.

Description

technical field [0001] The invention relates to a 3D printing device and a printing method thereof, belonging to the technical field of printing equipment. Background technique [0002] A 3D printing device, also known as a three-dimensional printer, is a machine that uses cumulative (additive) manufacturing technology (that is, rapid prototyping technology). Its principle is to put data and raw materials into a 3D printer, and the machine will process products layer by layer made. At present, the 3D printing device is more common to use SLA three-dimensional printing (also known as stereolithography, light modeling), which can be divided into two types according to different working methods: 1. The working platform is under the liquid surface, and the exposure mechanism is located above the working platform. ; 2. The working platform is on the liquid surface, and the exposure mechanism is located below the working platform. Among them, the specific working process of the ...
