Whether you’re optimizing your manufacturing process, rapidly iterating through designs, or assessing form, fit, and function, our Engineering Resins for the Form 2 / Form 3 are formulated to withstand extensive testing and perform under stress.

Supports Print Resolutions: 100 and 50 microns

Curing Period: 60min at 70 degrees

Due to its high elongation and moderate modulus Tough 1500 Resin is ideal for parts that bend, but require high memory retention. When pushed to its stress limit, Tough 1500 parts will strain significantly before permanently deforming and ultimately breaking.

Tough 1500 Resin is ideal for:

• Prototypes that repeatedly bend and quickly return to shape
• Jigs and fixtures requiring repeated deflection
• Simulating the strength and stiffness of Polypropylene (PP)

Tough Resin is the strongest and stiffest material in our functional family of Tough and Durable Resins. Choose Tough Resin for prototyping strong and sturdy parts that should not bend easily. Due to its high strength and modulus, Tough Resin can handle higher stress and will hold its shape better under load compared to Tough 1500 or Durable Resins. When pushed to its stress limit, Tough parts will bend slightly before ultimately breaking.

Durable Resin is the most pliable, impact resistant, and lubricious material in our functional family of Tough and Durable Resins. Durable Resin is perfect for squeezable plastic parts and low-friction assemblies that experience significant wear and tear. Due to its low modulus and high elongation, Durable Resin deforms significantly with relative ease under load compared to Tough (v5) and Tough 1500 Resins. When pushed to its stress limit, Durable parts will strain significantly before permanently deforming and ultimately breaking.

All Engineering resins requires UV post-cure when finishing for it to be fully cured, please consider the Form Cure to properly cure your functional resin prints.

Notes on Formlabs Resins and Proper use:

Formlabs Engineering resins come in a resealable and refillable 1 Litre Cartridge.
Resins should be handled in accordance with Formlabs protocols.

A new resin tank should be used per Resin colour/type for your Form 2 / Form 3 printer.
Never mix the use of resin colours or types with a resin tank.
