Background
The 3D printer, also called three-dimensional printer, is a machine of an accumulative manufacturing technique, i.e. a rapid prototyping technique, which is a machine based on a digital model file, and manufactures a three-dimensional object by printing a layer of adhesive material by using a special wax material, powdered metal or plastic and the like. Three-dimensional printers are currently used to manufacture products. Techniques for building objects in a layer-by-layer printing manner. The principle of the 3D printer is that data and raw materials are put into the 3D printer, and the machine can build products layer by layer according to programs; some 3D printers use an "inkjet" approach. I.e. a very thin layer of liquid plastic material is sprayed onto the mould tray by means of a printer head, and the coating is then subjected to uv light. Then the mould tray descends a very small distance for the next layer to be stacked; also, a technique called "deposition molding" is used, in which plastic is melted in a nozzle and then a thin layer or the like is formed by depositing plastic fibers.
