TC-85 is a bio-compatible photoreactive polymer that allows you to print your aligners directly. Benefits: uniform thickness, avoiding the usual thinning of a thermoforming sheet. This uniform thickness in turn provides a constant force level over th e whole aligner and also a better fit of the aligner afterwards. file:///C:/Users/chf/AppData/Local/Microsoft/Windows/INetCache/Content.Outlook/DF3WDT1V/Info233_Graphy_EN_final_web.pdf
