With every new resin Formlabs releases, the list of possibilities grows. Learn which resins are recommended for which use cases here.
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.
TIPBe 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!
To learn more about the performance properties of each Formlabs resin, refer to the library of material properties datasheets.
Which Resin to Use
Clear: Transparency, polishes to near optical clarity, great for internal channels and working with light.
White: Neutral and matte tone, slight translucency when thin. Works well for sanding, and provides a great base color for painting prints.
Grey: Neutral and matte tone, great for showing off surface finish and for printing small, accurate features, photographs easily.
Black: Highly pigmented, our most opaque, high detail resin. Matte surfaces, great for printing small, intricate features.
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.
Durable: Use to prototype models that will eventually be made from polypropylene (PP) or high density polyethylene (HDPE). Consider using where high elongation, deformation, and/or impact resistance are required.
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.
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)
Dental Model: Highly accurate and specifically formulated for printing crown and bridge models with removable dies.
