3d printer and its printing method

Abstract

The invention discloses a 3D printer and a printing method thereof, comprising a printer body, the printer body includes a cabinet and a bracket arranged on one side of the cabinet, a laser scanning device is provided on the bottom of the cabinet, and a reflector is provided in the center of the bottom of the cabinet to reflect There is a resin tank directly above the mirror, the bottom surface of the resin tank is fixed with high-transmittance quartz glass, the high-transmittance quartz glass is fixed on an iron plate, and a suspension platform is provided directly above the resin tank. The table is connected to the second lifting device; because the first lifting device and the second lifting device are linked, the 3D printer and its printing method of the present invention not only simplify the control process, but also facilitate the thickness of the resin sheet of the cross-sectional profile of the product. accurate control.

Description

Technical field: [0001] The present invention relates to the technical field of 3D printers, in particular, to 3D printers and printing methods thereof. Background technique: [0002] Using a printer is like printing a letter: Tap the "Print" button on a computer screen, and a digital document is sent to an inkjet printer, which sprays a layer of ink onto the surface of the paper to create a second copy. dimensional image. With 3D printing, software completes a series of digital slices through computer-aided design (CAD) and sends information about those slices to a 3D printer, which stacks successive thin layers until a solid object is formed. The biggest difference between a 3D printer and a traditional printer is that the "ink" it uses is a real raw material. [0003] There are various forms of stacking thin layers. Some 3D printers use an "inkjet" method. For example, an Israeli 3D printer company called Objet uses a printer nozzle to spray an extremely thin layer of...

Problems solved by technology

[0009] The technical problem solved by the present invention: In the prior art rapid prototyping SLA 3D printer, after completing a printing action, the hanging table moves up along the vertical slide rail, and at the same time, the motor drives the iron plate to pull down, and then drives the resin tank Move down, eliminate the vacuum force in the resin tank through this pull-down action, and then the motor drives the iron plate to pull up, and then drives the resin tank to move up to perform the next printing action; the above-mentioned last printing action to the next printing action The hanging action of the 3D printer and the lifting action of the resin tank are carried out independently of each other, the control process is complicated and it is not conducive to the accurate control of the thickness of the resin sheet of the cross-sectional profile of the product
