5. 3D Printing:

3D printing is a newly arising production technology, which includes many forms. The most common way of 3D printing is to heat the raw materials of thermoplastic by 3D printer, and through computer aid graphic design and parameter setting, then extrude thermoplastic layer by layer to finished the product. Due to its convenience, high speed and low cost, it is often used in product development. Compared to the past, making sample by using 3D printing technology can greatly reduce the processing time and mold developing cost.
