1. At the end of the 19th century, the United States developed advanced photographic sculpture and landform shaping technology, and subsequently developed the core manufacturing idea of ??3D printing printing technology.
2. Before the 1980s, the number of 3D printers was very small, and most of them were concentrated in the hands of "Frankensteins" and electronic product enthusiasts. Mainly used to print things like jewelry, toys, tools, kitchen supplies and the like. There are even automobile experts who print out automobile parts and then customize the real commercially available parts based on the plastic models.
3. In 1979, American scientist RF Housholder obtained a patent for a similar "rapid prototyping" technology, but it was not commercialized.
4. By the late 1980s, American scientists invented a printer that could print three-dimensional effects and successfully introduced it to the market. 3D printing technology has matured and been widely used. Ordinary printers can print some reports and other flat paper materials. This newly invented printer not only reduces the cost of making three-dimensional objects, but also stimulates people's imagination.
1. A 3D printer is a device that can "print" real 3D objects. It is a type of industrial robot. It can not only "print" a complete building, but can even be used in aerospace. Print the shape of any item needed in the spacecraft for the astronauts.
2. 3D printing technology used to be used to make models in the fields of mold manufacturing, industrial design and other fields. Now it is gradually used in the direct manufacturing of some products. This technology is becoming popular.
3. Its principle is: put the data and raw materials into the 3D printer, and the machine will create the product layer by layer according to the program. The printed products can be used immediately, and food can also be printed with a 3D printer.
4. The biggest difference between 3D printers and traditional printers is that the "ink" they use is real raw materials. There are various forms of stacked thin layers, and there are various types of media that can be used for printing, from a wide range of plastics to metals, ceramics and rubber-like substances. Some printers can also combine different media, making the printed object hard on one end and soft on the other.
