3D printer

Abstract

The invention discloses a 3D printer, and relates to the technical field of 3D printers. The 3D printer comprises a printing box, wherein windows are evenly formed in the outer surface of the printing box, first sliding grooves are fixedly connected to the inner surfaces of the windows on the left side and the right side, rolling windows are slidably connected to the inner surfaces of the first sliding grooves, a transverse plate is fixedly connected to the inner surface of the printing box, a through groove is formed in the outer surface of the transverse plate, sliding rails are fixedly connected to the top and the bottom of the printing box, and a printing head is slidably connected to the outer surface of the sliding rail at the top. An operation table capable of moving back and forth is arranged inside the printing box, when the printing head performs printing, the corresponding position of the operation table can be adjusted along with the printing of the printing head, then a produced object can be fixed through a fixing mechanism, and the situation that due to adjustment of the position of the operation table or some external collisions during printing, the whole object moves, the upper and lower shapes of the object are not consistent, defective products are produced, and raw materials are wasted is prevented.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a 3D printer. Background technique [0002] 3D printing is a kind of rapid prototyping technology, also known as additive manufacturing. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. . 3D printing is usually achieved using digital technology material printers. It is often used to make models in the fields of mold manufacturing and industrial design, and is gradually used in the direct manufacture of some products. There are already parts printed using this technology. [0003] 3D printing technology is gradually being widely used, such as making models that are easy for patients to swallow and for experimental groups to study and make models. The existing 3D printers can print a real object according to drawings and materials, but when the 3D printer is working,...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a 3D printer, which solves the problem of lack of stabilizing devices inside the machine, which will also affect the printing effect and cause waste of raw materials when encountering collisions or vibrations

Prevent the overall displacement of the item due to the adjustment of the position of the console or some external collisions during printing, resulting in inconsistency between the upper and lower shapes of the item and the production of defective products
