3D printing, is a kind of rapid prototyping technology, it is the combination of intelligent manufacture and materials science laws, using the powder can be bonded material such as metal or plastic, through the printing way to construct the object step by step, finally forming products。

The biggest advantage of 3D printing is high accuracy, smooth surface, speed, greatly shortened product development cycle, improve productivity and reduce production costs. 3D printing is widely used in automotive, aerospace, medical apparatus and instruments appliances, anime, etc
