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.
High Resolution
For demanding applications, our carefully-engineered resins capture the finest features in your models.
Smooth Surface Finish
Parts printed on Formlabs SLA printers have the polish and finish of a final product.




Applications
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

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.
