Product Overview


Formlabs Grey Resin Cartridge v4 1L
3D print strong, precise concept models and prototypes that bring your ideas to life with Formlabs’ library of Standard Resins. With a matte surface finish, opaque appearance, and precise details, prints are ready to use right off the printer. Their neutral undertone makes a great base for parts that will eventually be painted or undergo other finishing processes.

Post-Processing
Form Wash Settings
10 min in IPA
NOTES
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
NOTES
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.
