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.
Black: Highly pigmented, our most opaque, high detail resin. Matte surfaces, great for printing small, intricate features.
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.
Color: 16 supported colors, with opaque and matte finish. Colorful prints, without the manual work of finishing and painting.
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.
Rigid: Reinforced with glass to offer very high stiffness and a polished finish. Highly resistant to deformation over time. Great for printing thin walls and features. Not suited for parts that must bend.
Grey Pro: Highly resistant to deformation over time. Versatile material. Suitable for concept modeling, functional prototyping, and parts intended for repeated use or handling.
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.
Dental LT Clear: High resistance to fracture and wear, ideal for hard splints and retainers. Polishes to high optical transparency. Class IIa biocompatible.
Ceramic: A composite, silica-filled resin. Can be fired in a kiln or furnace to create a fully ceramic piece. This experimental Form X material requires more trial and error than other Formlabs products.
Layer Height Options

|Clear Resin||Form 1+|
|White Resin||Form 1/1+|
|Color Resin (Form 2 only)|
|High Temp Resin|
|Durable Resin (Form 2 only)|
|Rigid Resin (Form 2 only)|
|Grey Pro Resin (Form 2 only)|
|Dental Model Resin (Form 2 only)|
|Dental SG Resin (Form 2 only)|
|Dental LT Clear Resin (Form 2 only)|
|Ceramic Resin (Form 2 only)|
Which Resin Tank to Use
Check the chart below to learn about resin tank compatibility for different Formlabs resins. Some resins, such as Dental SG Resin, Dental LT Clear, and High Temp Resin, are known to wear down tanks more quickly. For these materials, print using Resin Tank LT (Long Term) for best results and a longer tank lifetime.
- A ✔ (check mark) indicates compatibility.
- An (X mark) indicates incompatibility.
- Recommended indicates the Formlabs-recommended resin tank for the specific material.
- Required indicates the resin tank required for the specific material.
|Resin Type||Standard Resin Tank||Resin Tank LT (Long Term)|
|Engineering||Grey Pro Resin||Required|
|High Temp Resin||Recommended|
