3D printer with edge warping prevention function

Abstract

The invention relates to the technical field of 3D printing equipment, in particular to a 3D printer with an edge warping prevention function. A switching assembly comprises a lifting part fixedly arranged on the inner bottom wall of a box body and a rotating assembly arranged on the lifting part; the lifting part is used for driving the rotating assembly to ascend and descend in the box body; the rotating assembly includes a rotating shaft, a driving part and two trays, wherein the lower end of the rotating shaft is rotationally connected to the lifting part, the driving part is fixedly arranged on the lifting part and used for driving the rotating shaft to rotate, and the two trays are fixedly arranged at the upper end of the rotating shaft; and a processor is electrically connected to a printing device, a glue brushing device, the lifting part and the driving part, so that the rotating shaft is driven to rotate through a control instruction of the processor so as to drive the two trays to be paused under the glue brushing device and the printing device respectively, and the tray brushed with glue through the glue brushing device rotates to the position under the printing device. The problems that an existing 3D printer is low in printing efficiency, a printing material falls on a tray and shrinks when cooled, and a printed sample is prone to edge warping are solved.

Description

technical field [0001] The invention relates to the technical field of 3D printing equipment, in particular to a 3D printer with an edge warping prevention function. Background technique [0002] 3D printing is a kind of rapid prototyping technology. 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 realized by using digital technology material printers. 3D printing technology is widely used in various industrial or civil fields. Its simple way of directly outputting three-dimensional objects through 3D drawings greatly simplifies the proofing process in industry. The fun and motivation of innovation and creativity have been strengthened, and the 3D printing technology has been developed rapidly. [0003] During the operation of the existing 3D printer, after a sample is printed, the tray needs to be cleaned before the second printing can be p...
