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.

Why Choose Grey Pro Resin?

Grey Pro Resin is a tough and heat resistant material that has increased elongation and improved toughness compared to Formlabs Standard Resins.


Low Creep
Able to withstand high stress and hold its shape overtime.


High Heat Resistance
Allow hot air, gas, and fluid flow through your parts.


Tough
Handle parts repeatedly, knowing parts will absorb shock and impact energy without breaking.


High Precision
Create looks-like prototypes with smooth surfaces that show fine detail.

Applications

Grey Pro Resin is ideal for concept modeling and versatile and functional prototyping. It is a versatile material suitable for both looks-like prototypes and rigorous hands-on testing.

Consider Grey Pro Resin for:

Mold masters for plastics and silicones
Injection molded product prototypes
Form and fit testing
Jigs and fixtures for manufacturing

Notes

For parts printed in an engineering-focused resin (such as those in the Rigid, Tough & Durable, and Flexible & Elastic families), post-curing ensures that the parts reach their optimal mechanical properties and can function as designed. There is only one recommended post-curing time for Grey Pro Resin.
