3D printing has gradually extended from the early FDM, SLA technology has appeared in nearly dozens of large and small enterprises self-naming technology. There are three main categories of materials: metal, non-metal, and biological materials. From the perspective of the current industry of 3D printing embedding, it has basically involved various fields such as automobiles, military industry, aerospace, education, medical treatment, and film and television.
3D printers are mainly divided into desktop-level and industrial-level devices. The desktop grade can be used directly in the office, and the print size is relatively small, while the industrial grade can be placed in the factory, the print size is large, or it can be used directly in the office and home.
Some 3D printers use soluble plastic as the material, and use the melt-stacking method (FDM) to print some models with low accuracy requirements, which is absolutely sufficient as a model.
Some 3D printers use photosensitive resin as the material and use light curing technology to print high-precision models. For example, printing individualized mobile phone cases is very beautiful.
Some 3D printers use living cells as materials to print human organs, which is a relatively high technology in the 3D printing industry.
Others can print chocolates, print houses, etc.
There are also printed clothes, but they have appeared as film and television props and have not been commercialized.
The common 3D printers at this stage mainly serve the manufacture of models. In the future, there will be a wider application space, reaching the stage of "only can't think, can't make".
