Problems solved by technology

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; When heat-setting expands, the combination of the part of the printed object that has cooled down and the part that has just been heat-cured has a certain impact on the strength; at the same time, if the printing thickness is too large, the laser penetrates too deep into the powder, which will cause a certain loss of laser light. influences

Abstract

The invention relates to a huge three-dimensional (3D) printer in the air, which comprises a material extruding device, a material supporting device and induction brush electric wheels, wherein the material extruding device is composed of a cone-shaped tube, a cone-shaped material extruding screw, a feed hopper, a square tube, a connecting shaft and the like; the supporting device is composed of a material supporting plate, a powder scraping rotary wheel, a material receiving hopper, a material receiving straight tube and the like; the induction brush electric wheels are divided into a front induction brush electric wheel and a rear induction brush electric wheel, the front induction brush electric wheel can not be too far away from the rear induction brush electric wheel, and points where the front induction brush electric wheel and the rear induction brush electric wheel are contacted with a printed object are located at the periphery of the printed object near a thermal curing area. The huge 3D printer in the air is characterized in that a supporting arm is connected with and supports the material extruding device and the material supporting device simultaneously, and the material extruding device and the material supporting device move along with the supporting arm synchronously in the same direction; and the front induction brush electric wheel and the rear induction brush electric wheel move along with the supporting arm synchronously in the same direction.

Description

technical field [0001] The invention relates to a super-large 3D printer in the air, belonging 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; When heat-setting expands, the combination of the part of the printed object that has cooled down and the part that has just been heat-cured has a certain impact on the strength; at the same time, if the printing thickness is too large, the laser penetrates too deep into the powder, which will c...
