Overview

Tough 1500 Resin V2 is a resilient material with strength, stiffness, and toughness comparable to polypropylene (PP), offering exceptional resistance to fractures, impacts, and shattering.
Fast Model Resin is Formlabs’ fastest resin, capable of printing at speeds of over 100 mm per hour. Print dental models in minutes or large prototypes in less than two hours. Formulated specifically for the Form 4 ecosystem, this material prints three times faster than the previous version.
