Why Choose Grey Resin?

Leverage Grey Resin to iterate on high-resolution prototypes and models that capture astonishing detail without sacrificing strength.

Matte Appearance

Produce prints with smooth, opaque surfaces ideal for model making and looks-like prototyping, rivaling injection-molded plastics.

High Part Quality

Create elegant, enticing parts without sanding, polishing, or priming.

Ease of Use

Start using your parts quickly, as Formlabs’ Standard Resins only need minimal post-processing.

Neutral Undertone

Paint or use other finishing processes to elevate your model or prototype.


Grey Resin supports high detail with a smooth, matte surface finish with great mechanical properties.

Consider Grey Resin for:

General purpose prototyping and design
Models with very small features and intricate details
Base for painted prints
Presentation-ready pieces

Material properties may vary based on part geometry, print orientation, print settings, and temperature. Data was obtained from parts printed using Form 2, 100 μm, Clear settings and post-cured with 1.25 mW/cm³ of 405 nm LED light for 60 minutes at 60°C.


Form Wash Settings


10 min in IPA


When using a single wash bucket, residue from previously washed parts deposits on part surfaces. If washing darker-colored materials like Black Resin in the same wash bucket as lighter-colored materials like White Resin or Clear Resin, some color transfer may occur.

Form Cure Settings


30 min



60 °C


All standard opaque Formlabs resins (including Grey, Black, White, Color, and Model Resin) have equivalent mechanical properties. While the recommended post-cure time is 30 minutes, post-curing for 60 minutes will result in a small additional gain in tensile modulus. This post-cure setting can be used with any of these resins.
