What is a 3D printer

The name 3D printer is a new word in recent years for the civilian market. In fact, he has another name in the field of expertise, rapid prototyping technology". Rapid prototyping technology and rapid prototyping (Rapid Prototyping Manufacturing, referred to as RPM), was born in the late 1980s, is one of the advanced manufacturing technology based on the method of material accumulation, is regarded as a great achievement in the last 20 years in the field of manufacturing. It is a set of mechanical engineering, CAD, reverse engineering technology, layered manufacturing technology, numerical control technology, material science, laser technology, can automatically and directly, quickly and accurately transform the design prototype for a certain function or production parts directly, making, so as to prototype new design ideas to the check etc. provides a means to achieve a high efficiency and low cost. Namely, rapid prototyping technology is the use of three-dimensional CAD data, through the rapid prototyping machine, the layers of the material into a solid prototype.
