How to Identify Your Resin Version

PreForm prompts you to identify your resin type and version when setting up each print. The material select dialog looks like this:

First, select your material. If the material only has one version, it will automatically select. If the material has multiple formulation versions, refer to the full formulation number on the bottle or cartridge label. If there is no visible formulation number, it is the formulation number ending in 01.

After choosing the material, select the correct layer thickness before beginning the print.

Tip

Be careful to never mix resins, even if they are different versions of the same color. Use a different resin tank for each resin to ensure successful prints!

Which Resin to Use

Standard Resins

Clear: Transparency, polishes to near optical clarity, great for internal channels and working with light.
White: Neutral tone, slight translucency when thin, provides a great base color for painting prints.
Grey: Neutral tone, slight translucency when thin, great for showing off surface finish, photographs easily.
Black: Highly pigmented, our most opaque, high detail resin, great for printing small, accurate features.

Engineering Resins

Flexible: Simulates an 80A durometer rubber. Choose for impact resistance and compression, great for ergonomic soft-touch grips.
Tough: Simulates ABS plastic. Choose for applications that will undergo high stress and strain. Great for functional prototyping of assemblies, machining, snap-fits and living hinges.
High Temp: Has an HDT of 289 °C @ 0.45 MPa. Choose for static applications that will experience high temperatures, including moldmaking processes such as thermoforming, vulcanization, and electronics encapsulation.

Jewelry

Castable: Developed for clean burn out and high detail. Choose for direct investment casting, resin is blue in color, and slightly softer than standard resins before post-curing.

Biocompatible Resins

Dental SG: Designed to directly print surgical and pilot drill guides. Class 1 biocompatible resin (EN-ISO 10993-1:2009/AC:2010, USP Class VI)
