Zortrax launches biocompatible 3D printing resins for dental and prosthetic applications

Zortrax has announced new biocompatible resins that have been optimised for its Inkspire 3D printing platform for dental and prosthetic applications. The company launched its Inkspire machine last year and has followed it up with dedicated materials for temporary crowns and bridges and surgical guides. Raydent Crown & Bridge is class IIa biocompatible, ensuring it is safe for it to contact human tissue for up to 30 days, and boasts high abrasion resistance guaranteeing permanent smooth surfaces and anatomical shape for the duration of its usage. Raydent Surgical Guide, meanwhile, has been developed for the printing of precise prosthetic surgical guides. With Class I biocompatibility, the Surgical Guides grade is safe for transient contact with human tissue. The material is also translucent to enhance visibility, features high dimensional accuracy to enable correct placement of implants or guidance for tools, and low viscosity and water resistance to make the guides easy to wash.
