Abstract

An air 3D printing material extruding and holding apparatus comprises a material extruding device and a material holding device, the material extruding device is composed of a conical tube, a tapered material extruding screw, a feeding hopper, a square tube and a connecting shaft, and the material holding device is composed of a material holding plate, a powder scraping rotating wheel, a material receiving hopper and a material receiving straight tube; the tapered larger opening end of the tapered tube is upward and is connected with the feeding hopper, the tapered material extruding screw is arranged in the tapered tube, the connecting shaft and a motor are arranged at the upper end of the tapered material extruding screw, the small opening end of the tapered tube is downward and is connected with the square tube, an oblique square opening is arranged at one end of the square tube far away from the tapered tube, and the material holding plate is arranged in a position having a preset distance to the oblique square opening and just below the oblique square opening; and the material receiving hopper is arranged below the material holding plate, the lower end port of the material receiving hopper is connected with the material receiving straight tube, the lower end of the material receiving straight tube is connected with a flexible tube, the body of the material receiving hopper is connected with a support arm, and the support arm is connected with the tapered tube and supports the tapered tube and the feeding hopper.

Description

technical field [0001] The invention relates to a 3D printing extruding and supporting device in the air, and belongs to the technical field of 3D printing. Background technique [0002] Since humans invented 3D printing technology, 3D printing has entered the lives of ordinary people in a few years, but 3D printing has developed the fastest in the field of military technology, especially in the research and development and trial production of military equipment, which has greatly accelerated the development of military technology. develop. However, the largest area of ​​3D printing in the world can only be a few square meters, which hinders the development of large-scale industrialization of 3D printing. Contents of the invention [0003] The purpose of the present invention is to provide an aerial 3D printing extruding and holding device capable of printing infinitely large objects using 3D printing technology. [0004] Aerial 3D printing extrusion and supporting devi...
