Since its launch, 3D printing has developed continuously. At present, it has many advantages, such as personalization, small batch, high efficiency and so on. 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 far exceeds many traditional processes and has high industrial application value.

At present, the achievements of 3D printing in the medical field are the most remarkable, because it is not only a scientific and technological innovation, but also related to everyone's health. Among them, the most famous is that a university in Israel successfully printed a "complete" heart with cells, blood vessels, ventricles and atrium. Although it is only the size of rabbit heart, it shows that 3D printing plays an important role in medical treatment.

In addition to biological printing, 3D printing has also made considerable achievements in non biological printing. The most mature application is in the field of dentistry. With the development of 3D printing technology and the application of digitization, when going to the dental department to see teeth, dentists can directly scan the patient's mouth with a scanner, generate a 3D digital model and send it to a 3D printer for printing, so as to quickly obtain a high-precision dental model. The orthodontic braces printed in 3D can be worn directly, which improves the treatment efficiency and the treatment experience of patients' oral occlusion.

Compared with traditional orthodontic appliances, 3D printing transparent orthodontic appliances are not only invisible and beautiful, but also the size is more suitable for the patient's tooth state at each stage during the correction. 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 orthotics.

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