英文摘要 |
3D printing technology is used for rapid prototyping and "additive manufacturing". It is used to manufacture products using layer by layer stacking manner. The 3D printing model is of almost accuracy and high practical value. 3D printing products have been applied to all aspects of life. American Society for Testing and Materials (ASTM) classifies common 3D printing technologies into 7 types, including: (1)vat photopolymerization, (2)powder bed fusion, (3)binder jetting, (4)material jetting, (5)sheet lamination, (6) material extrusion, (7) directed energy deposition, and (8) hybrid. 3D printing technology can be applied to teaching, pre-operative planning, manufacturing surgical tools and customized implants, with high clinical value. In recent years, 3D bioprinting technologies use cells, substrates and specific materials to make biological products. It can be expected that more and more new technologies and products will be developed in the future. |
