3D printer is also called 3D printer and 3D rapid prototyping machine. It is a cumulative manufacturing technology that can directly generate objects from computer graphics data. It was initially widely used in industrial design, medicine, etc. Compared with ordinary printers, the biggest difference between 3D printers is that 3D printers use real raw materials, such as special wax materials, powdered metals, ceramics, rubber substances, plastics and other adhesive materials. Three-dimensional objects are manufactured by printing layers of adhesive materials. After continuous innovation and improvement, the designer has made innovations in structural design, appearance design, color, material, man-machine, etc. In terms of structural design, the built-in air filter device can effectively handle the printing smell, effectively reduce the spread of the printing smell, provide a safe use environment, and improve the printing quality. In terms of appearance design, the 3D printer design is simple and atmospheric, intuitive and tidy, and the materials are selected by the designer's comparison, with exquisite texture and convenient processing. In terms of use, the designer took into account the man-machine aspect, equipped with aluminum alloy handle, easy to carry; Touch screen control, use is very convenient; Added the reminder function of consumable exhaustion. With the continuous innovation of science and technology, the continuous improvement of 3D technology, the application field is more and more extensive, and it is beginning to be accepted by families. The 3D printer has superior functions. It not only supports mobile phone client access printing, but also can find, download, collect, print, and even directly share models in the client. It can print tableware, vases, toys, etc., bringing people's lives More convenience.
