Over the course of the past decade, the dental industry has been revolutionized by 3D printing . Several different applications of have been developed, from fixing broken teeth to making flossing easier. Printing is done both in the dentist’s office and in labs, and it brings a new level of speed and ease to old procedures.
In dental 3D printing, prosthetics and orthodontics have to be printed with extreme precision to ensure a perfect fit. Such accuracy is only possible through resin-based printing, such as stereolithography (SLA) and digital light processing (DLP) printers. In these technologies, printed layers of resin are solidified (cured) by a light source: a laser in SLA printers and a projector in DLP. Recently, another technology, called PolyJet, has started being used by some manufacturers, with simpler processes and superior results.
