EnvisionTEC’s E-Partial chemistry was developed for building partials where some flex is required. E-Partial material maintains flexural strength to ensure clasp flex without breakage. The stiffness of the material allows for the production of a very hard retention grid and super tight thin clasps to deliver a metal partial with the perfect every time. Printing partials is a snap with E-Partial material and EnvisionTEC 3D printers. Unattended production capabilities mean the machine can work while you are away - it will even turn itself off after completing a build.
