3D Printing (ThreeDimension Printing (3 dp) technology, refers to the physical layer through continuous overlay, step by step increase the technical materials to generate 3D entity, and the traditional removal material processing technology is different, so also known as add manufacture or add material (AdditiveManufacturing, AM) technology, formerly known as rapid prototyping (RapidPrototyping, RP) technology.
As a comprehensive application technology, 3D printing integrated digital modeling technology, precision machinery, mechanical and electrical control technology, information technology, materials science and chemical cutting-edge technology of many aspects, such as knowledge, has the very high technology content.
