In recent years, due to the rapid development of digital dentistry, 3D printing has gradually become an important production tool in dental laboratories and clinics. Professional printing centers and good manufacturing practice (GMP) production plants have been continuously put on the market, and materials with new properties and functions have been continuously entering the market. In the circumstance of high competition, 3D printers are getting more accurate, faster, and inexpensive. This trend brings advantages, but also some disadvantages and safety issues to clinical processes. How to regulate printed devices has always been a topic of common concern of regulatory agencies in various countries. In view of the above situation, this chapter organizes 3D printing-related topics as the object of discussion, including printing workflow management, risk, regulatory supervision, safety, and future trend.
