Whether you’re optimizing your manufacturing process, rapidly iterating through designs, or assessing form, fit, and function, our Engineering Resins for Formlabs stereolithography (SLA) 3D printers are stare formulated to withstand extensive testing and perform under stress. Grey Pro Resin’s high precision, moderate elongation, and resistance to deformation over time make it a versatile material suitable for a wide range of engineering applications. Supports print resolutions: 100 and 50 microns. Post-curing required. Requires Resin Tank LT for Form 2. Requires Form 3 Resin Tank V2 for Form 3. 

Grey Pro Resin decreases the lifetime of resin tanks.

Notice: Form 3 Resin Tank V1 is incompatible with Rigid, Grey Pro, Elastic, and Tough 2000 Resins. There are two versions of the Form 3 Resin Tank: Tank V1 and Tank V2. Read more about tank versions, lifetime, and maintenance in our support article.
