Clear Resin 1 L



3D print strong, precise concept models and prototypes that bring your ideas to life with Formlabs’ library of Standard Resins.
Clear Resin is great for fluidics and mold making, optics, lighting, and any parts requiring translucency or showcasing internal features. Stereolithography 3D printing technology makes clear prints possible on the desktop.
Supports print resolutions: 100, 50, and 25 microns.<br />Post-curing recommended.

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.
