This chapter discusses recent applications and findings in additive manufacturing (AM), or 3D printing, applied in oral and maxillofacial surgery. The reader will get an introduction to the basics of AM technology followed by oral and maxillofacial applications like printing of anatomical models and the design and manufacturing of customised implants. Recent research on the biological response of some AM metal alloys is also discussed at the end of the chapter. © Springer Nature Switzerland AG 2020. All rights reserved.
