3D printing (3DP), also known as Additive Manufacturing Technologies (AM), is a technology that manufactures solid parts based on three-dimensional CAD data by adding materials layer by layer.
The historical development of 3D printing technology is a process of continuous improvement and expansion. From early rapid prototyping technology to today's widespread application, 3D printing technology has been used in the design and manufacturing fields of jewelry design, footwear design and manufacturing, industrial design, architectural design, engineering design and construction, automobile design and manufacturing, as well as aerospace, Dental and other medical fields.
