Whether you’re optimizing your manufacturing process, rapidly iterating through designs, or assessing form, fit, and function, our Engineering Resins for the Form 2 are 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, and Elastic Resins. There are two versions of the Form 3 Resin Tank: Tank V1 and Tank V2.
