3D printing service is a rapid prototyping technology, it is a digital model based on the file, the use of powdery metal or plastic and other adhesive materials, through the layers of the way to build objects to the 3D prototyping technology. 3D printing is usually done using a digital technology material printer. Often in the mold manufacturing, 3D rapid prototyping, industrial design and other fields are used to build the model, after the gradual use of some products with the direct manufacture, which has been used to print out the use of this technology component. The technology is used [...]
