A 3D printing method

Abstract

The invention belongs to the technical field of 3D printing, and particularly relates to a 3D printing method. The 3D printing method uses a material storage unit, and the material storage unit comprises a rubber bag, a feed inlet, a discharge pipe, a discharge valve, a conveying motor, an upper supporting plate, a spiral stirring shaft, a lower supporting plate, slide blocks and a fixing frame, wherein the slide blocks are correspondingly arranged at the upper end and the lower end of the fixing frame, one slide block is connected to the right end of the upper supporting plate through a connecting rod, and the other slide block is connected to the right end of the lower supporting plate; the rubber bag is arranged between the upper supporting plate and the lower supporting plate, the feedinlet is formed in the left upper end of the rubber bag, and the conveying motor is fixedly installed on the upper supporting plate; the spiral stirring shaft is rotatably installed on the conveyingmotor, and the discharge pipe is fixedly installed at the lower end of the rubber bag; and the discharge valve is connected in series with the discharge pipe; the rubber bag expands when raw materialsenter from the feed inlet, the rubber bag contracts when the discharge valve is opened for discharging; and the raw materials are not prone to adhering to the inner wall of the rubber bag, the utilization rate of the raw materials is effectively improved, the raw materials are stirred through the spiral stirring shaft, the solidification of the raw materials is prevented, and the printing qualityis improved.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and specifically relates to a 3D printing method. 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 a digital technology material printer, that is, a 3D printer. The principle of a 3D printer is to put data and raw materials into a 3D printer, and the machine will manufacture the product layer by layer according to the program. The biggest difference between a 3D printer and a traditional printer is that the "ink" it uses is a real raw material. There are various forms of stacking thin layers, and there are various types of media that can be used for printing, from a variety of plastics to metals, ceramics and rubber. class of substances. Some printers can al...

Afterwards, the mold tray drops a very small distance for the next layer to be stacked up. This kind of printing uses the storage unit to store the liquid raw materials required for printing. In reality, the conventional storage unit is mostly made of hard materials. Raw materials are easy to adhere to the inner wall, resulting in waste of liquid raw materials, increasing the cost of use, and solidifying on the inner wall of the storage unit after cooling, increasing the working time for cleaning
