Problems solved by technology

[0009] However, in the prior art, the driving devices are all gathered on one side, and the hanging body and the iron plate are all fixed on the end of the driving device in the form of a cantilever beam, which will cause uneven force when the hanging body and the iron plate move, The hanging body and the iron plate do not move up and down horizontally as a whole, and the hanging body and the iron plate will have a certain inclination, resulting in 3D printing quality deviation

Abstract

The invention discloses a 3D printer. The 3D printer comprises a cabinet body, driving devices and a laser scanning device, wherein the laser scanning device is arranged on the bottom surface of the cabinet body; a reflection mirror is arranged in the center of the bottom surface of the cabinet body; a resin groove is arranged over the reflection mirror, and highly transparent quartz glass is fixedly arranged on the bottom surface of the resin groove and fixedly arranged on an iron plate; a hoisting body is arranged above the resin groove. The driving devices comprise the first driving device and the second driving device, the first driving device is used for driving the hoisting body, and the second driving device is used for driving the iron plate. The driving devices are located in the center of the cabinet body, and drive the hoisting body and the iron plate overall during driving, the hoisting body and the iron plate are stressed evenly in the movement process and do not incline, and the printing effect is guaranteed.

Description

Technical field: [0001] The present invention relates to the technical field of printers, in particular to a 3D printer. 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 liquid plastic substance onto a...
