The most outstanding advantage of 1 and 3D printing technology is that it can directly generate parts with arbitrary shapes from computer graphic data, without mechanical processing or any molds, thus greatly shortening the product development cycle, improving productivity and reducing production costs. Compared with the traditional process, abandoning the production line reduces the cost and greatly reduces the waste of materials.
2. It can make shapes that can't be made by traditional production technology, so that people can design aircraft wings or heat exchangers more effectively.
3. With good design concept and technology, 3D printing technology can also simplify the manufacturing process and produce an article quickly, effectively and cheaply. Compared with the parts made by machines, the printed products are 60% lighter and equally strong.
Extended data:
The printing process of each layer of 3D printing technology is divided into two steps. Spray a layer of special glue on the area to be molded first. The glue drops themselves are very small and difficult to spread. Then spray a uniform layer of powder, which will solidify and bond quickly when it meets glue.
While areas without glue remain loose. In this way, under the alternation of a layer of glue and a layer of powder, the solid model is "printed" and shaped. After printing, as long as the loose powder is swept away, the model can be planed out, and the remaining powder can be recycled.
