Background

The 3D printing concept originated in the united states at the end of the 19 th century and was developed and popularized in the 80 s of the 20 th century, 3D printing was one of the latest high "dimensionalities" embodied in the science and technology fusion model, the photographic sculpture and the landform shaping technology developed in the united states at the end of the 19 th century, and the 3D printing core manufacturing concept of the printing technology was subsequently developed, and three-dimensional printers were few, mostly concentrated in the hands of "science monsters" and electronic product enthusiasts, and mainly used to print things and worries like jewelry, toys, tools, kitchen supplies and the like before the 80 s of the 20 th century. Even though there are automobile experts who printed out automobile parts and then ordered the real parts commercially available based on plastic models, in 1979, american scientist RF Housholder patented similar to the "rapid prototyping" technology but not commercialized, in the 20 th century 80 s there was a prototype entitled "rapid prototyping", in the middle of the 20 th century 80 s SLS was developed and patented by garkarl Deckard, university of austin, texas, the project was sponsored by DARPA, and in the late 20 th century 80 s, american scientists invented a printer capable of printing three-dimensional effects and had successfully marketed, and 3D printing technology was well developed and widely used. Conventional printers are capable of printing some reported flat sheet material. The printer of the latest invention not only reduces the manufacturing cost of three-dimensional objects, but also stimulates the imagination of people, the application of the 3D printer will be more extensive in the future, in 1995, the word of three-dimensional printing is created by martian workers, and the scheme of the ink-jet printer is modified by the graduates Jimbredt and Tim Anderson at the time, so that the solution of extruding the constraint solvent into powder instead of extruding the ink on paper is changed, and the sale of the three-dimensional printer is gradually expanded in 2003.
