What is the significance of 3D printing technology in medicine?

Nowadays, 3D printing technology has developed rapidly, involving more and more fields, and has also shown its own role in the dental field. 3D printing technology can not only print tooth fixators, but also print teeth. Researchers in the Netherlands have been studying 3D printed teeth. They printed an antibacterial tooth. This kind of tooth can kill drug-resistant bacteria and prevent problems such as tooth decay. Substances in teeth can kill bacteria that come into contact with them, but on the other hand, they are harmless to human cells. Adding basic polymers as alternative materials is one of the challenges facing the 3D printing industry at present, but adding active chemicals, such as using antibacterial salts, may be a great boon for the medical industry here. Aseptic or antibacterial 3D printing implants have a huge potential application range. It includes not only dental applications, but also other applications, such as plastic surgery septa and other polymer components for total hip or total knee replacement. In addition, the method of 3D printing antibacterial polymers can be easily transferred to other non-medical applications, such as food packaging, water purification, and even children's toys.
