3D printing

3D printing (3DP) is a rapid prototyping technology, which is a digital model file based on the use of powdered metal or plastic and other adhesive materials, through the layer by layer to print the way to construct the object technology.
3D printing is usually done using a digital technology material printer. Often in the mold manufacturing, industrial design and other fields are used in the manufacture of models, and gradually for some of the direct manufacturing products, has been printed using this technology from the parts. The technology is used in jewelery, footwear, industrial design, construction, engineering and construction (AEC), automotive, aerospace, dentistry and medical industries, education, geographic information systems, civil engineering, firearms and other fields.
Principle technology
The so-called 3D printer and general printer works basically the same, but the printing material is somewhat different, ordinary printer printing material is ink and paper, and 3D printer with metal, ceramic, plastic, sand and other "print material" is Real raw materials, printers and computer connections, through computer control can be "printed materials" layer together, and ultimately the computer into a blueprint for the entity. In layman's terms, a 3D printer is a device that "prints" out real 3D objects, such as printing a robot, printing a toy car, printing a variety of models, and even food. The reason why it is popularly referred to as the "printer" is a reference to the technical principle of ordinary printers, because the process of hierarchical processing and inkjet printing is very similar. This printing technology is called 3D stereoscopic printing technology.
There are many different techniques for 3D printing. They differ in that the components are created in a way that makes them available and builds in different layers. Materials commonly used in 3D printing are nylon fiberglass, durable nylon materials, gypsum materials, aluminum materials, titanium, stainless steel, silver, gold-plated, rubber-like materials.
