E-Guide Rigid PU is strong, flexible material with smooth finish.
Originally designed for industrial prototyping applications, DentCore tested it for dental diagnostic wax-up application with resounding success. Due to the high accuracy of the EnvisionTEC build styles, fitting and margin quality is excellent. The greatest advantage of the E-Rigid PU over milling wax discs is the reduced amount of finishing time. The nature of DLP 3D printing technology prevents all undercuts from forming, which creates accurate finish on the lingual surface. Embrasures are smoothly formed, as opposed to milling, where the burs would often leave irregularities. Sprues are much smaller and easier to remove. Finally, the surface finish is smooth and doesn’t need additional handling.
CAD/CAM has so much potential as technology continuously evolves. You never know where you may find new applications!
