Formlabs Engineering Tough 1500 Resin

Tough 1500 Resin produces stiff and pliable parts that bend and spring back quickly under cyclic loading. This material is ideal for functional prototypes, jigs and fixtures, and connectors undergoing temporary deflection. It also simulates polypropylene parts in terms of stiffness and strength.

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

Tough 1500 Resin is the most resilient material in our newly segmented family of Tough and Durable Resins. This family of resins, which includes Tough Resin, Tough 1500 Resin, and Durable Resin, behave relatively similarly under an applied force, but can be clearly differentiated by comparing key properties such as stiffness and elongation.

When To Use Tough 1500 Resin

Tough 1500 Resin is ideal for prototypes and connectors that bend and quickly return to shape, such as springs, snap fits, press fits, and hinges. 

Tough 1500 Resin is also ideal for jigs and fixtures that require repeated deflection and impact absorption. Balancing stiffness, strength, and impact resistance, Tough 1500 Resin is perfect for many manufacturing settings.

Prototype Polypropylene Parts With Tough 1500 Resin

Polypropylene is a common thermoplastic used in numerous consumer packaged goods products. Use Tough 1500 Resin to simulate the strength and stiffness of products that will be manufactured out of polypropylene.

Technical Deep Dive: Tough 1500 Resin

As with any material, to better evaluate when to use Tough 1500 Resin, it’s important to understand its technical properties. Tough 1500 Resin balances elongation and modulus, exhibiting high resilience and fast springback. 

  • Elongation is a measure of how far a material can stretch or bend.
  • Modulus is a measure of stiffness, or how easy it is to stretch or bend the material. 

Parts printed in this material can bend significantly and quickly spring back to their original shape.

The “1500” in Tough 1500 Resin represents its tensile modulus (in MPa). As Formlabs reformulates and develops new engineering materials, we will be transitioning to this “adjective + number” naming convention. In the case of the Tough and Durable Resins, we’ll continue using tensile modulus as the key distinguishing property, allowing you to identify where each material falls on a spectrum of stiffness.
