3D printer capable of realizing continuous printing

Abstract

The invention discloses a 3D printer capable of realizing continuous printing, comprising a rack, a spray head assembly, a printing assembly and a regulating assembly; the printing assembly comprises printing flat plates and a ball screw; the ball screw is mounted under the printing flat plates, the input end of the ball screw is connected with a stepping motor, and the output end of the ball screw is provided with slide blocks; and adsorption holes are formed in the slide blocks, are connected with a negative-pressure pipeline and are used for adsorbing and fixing the printing flat plates by virtue of negative pressure. According to the 3D printer provided by the invention, the printing flat plates are adsorbed through the adsorption holes by virtue of the negative pressure in a printing process, and after the spray head assembly finishes 3D printing on one printing flat plate, the printing flat plate moves along the axis direction of the ball screw under the action of the stepping motor, and the other printing flat plate is enabled to be located below the spray head assembly, so that continuous printing is realized; and the vacuum of the adsorption holes located under the printing flat plate finishing printing is closed, so that the printing flat plate can be directly taken away by working staff.

Description

technical field [0001] The invention belongs to the technical field of rapid prototyping, and in particular relates to a 3D printer capable of continuous printing. Background technique [0002] 3D printer, also known as three-dimensional printer, is a machine 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. It is a cumulative manufacturing technology that creates three-dimensional objects by printing layers of adhesive materials. The basic principle is that by putting data and raw materials into the 3D printer, the machine will build the product layer by layer according to the program, and The product is printed out and ready for immediate use. 3D printers used to be used to make models in the fields of mold making, industrial design, etc., and are now gradually being used for direct manufacturing of some products, which can be used...

AI Technical Summary

Problems solved by technology

Since the plate holes on the current printing plate are cylindrical holes with the same size up and down, it is difficult to remove the printed parts from the printing plate or remove the fixed materials left in the plate holes, which is very difficult for 3D printing. The follow-up cleaning work brings inconvenience; at the same time, because the printing plate is located under the nozzle assembly, it causes a lot of inconvenience when picking up parts, and the efficiency is low during continuous printing
