After continuous development since its appearance, 3D printing has many advantages such as personalization, small batch and high efficiency. At present, 3D printing technology is mainly used in aerospace, automobile manufacturing, medical treatment, jewelry, hand-made models, electronic parts, film and television props and other industries. In terms of value, it is far more than many traditional crafts and has very high industrial application value.


At present, the application of 3D printing in the medical field has made the most remarkable achievements, because it is not only a technological innovation, but also related to everyone's health. Among them, the most famous is the "complete" heart with cells, blood vessels, ventricles and atrium successfully printed out by an Israeli university in 2019. Although it is only the size of a rabbit heart, it shows the important role of 3D printing in medical treatment. In addition to bioprinting, 3D printing has also made considerable achievements in non bioprinting. Among them, the most mature application is in the field of dentistry. With the development of 3D printing technology and the application of digitization, dentists can directly scan the patient's mouth with scanners when they go to the dentistry department to see teeth in this way, generate a 3D digital model and send it to a 3D printer for printing, so that they can quickly obtain a high-precision dental model. The 3D printed orthodontic braces can be directly worn, which improves the efficiency of medical treatment and improves the experience of patients with oral occlusion.

Compared with traditional orthodontic appliances, 3D printed transparent orthodontic appliances are not only invisible and beautiful, but also more suitable for the patient's tooth state at every stage during orthodontic treatment. With the current 3D printing technology combined with oral scanning, dental laboratories can accurately and quickly produce a series of dental products such as crowns, bridges, dental models and orthodontic appliances.

Of course, with the continuous progress of society and science and technology, as well as the continuous deepening and promotion of 3D printing manufacturers at home and abroad in the medical field, the awareness of 3D printing in the society will continue to improve, and the application scenarios of 3D printing in the medical field will become more and more abundant. At that time, 3D printing will also have broader development prospects in the medical industry.
