Why Choose Clear Resin?

Clear Resin is a rigid material that polishes to near optical transparency, making it ideal for working with light or showcasing internal features.

Optical Transparency

Create transparent objects with minimal post-processing.

Smooth Surface Finish

Parts printed on Formlabs SLA printers have the polish and finish of a final product.

High Resolution

For demanding applications, our carefully-engineered resins capture the finest features in your models.


Clear Resin is ideal for creating clear prototype parts, showing internal cavities and details, housing LEDs, creating windows, or printing see-through anatomical models and devices.

Consider Clear Resin for:

Parts requiring optical translucency
Optics and lighting
Fluidics and moldmaking
Showcasing internal features

1 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.
