Tough 1500 Resin is a resilient, skin-safe material with strength and stiffness similar to polypropylene (PP). It’s ideal for stiff, pliable parts that bend and spring back quickly, including prototypes, jigs, and fixtures that undergo repeated deflection.

Certified for skin contact, Tough 1500 Resin is also well-suited for wearables, PPE, and consumer products. To maintain skin-safe certification, all recommended post-processing conditions must be followed precisely.

IMPORTANT: 5 L Container Requires a Resin Pump (Form 4)(Form 3) to work.

frequently asked questions

What is Tough 1500 Resin V1 used for?

It’s ideal for creating durable, flexible parts that bend and quickly return to shape—such as jigs, fixtures, snap fits, and functional prototypes.

How does Tough 1500 Resin V1 compare to other Formlabs Tough or Durable resins?

Tough 1500 sits between Tough 2000 (stiffer, stronger) and Durable Resin (softer, more flexible), offering a balanced blend of strength and flexibility.

What are the mechanical properties of Tough 1500 Resin V1?

It has a tensile strength of about 33 MPa, a modulus of 1.5 GPa, and an elongation at break around 51%, similar to polypropylene.

Is Tough 1500 Resin V1 suitable for end-use parts?

Yes — it’s great for low-volume production, functional prototypes, and assemblies that experience bending or repeated stress.

What post-processing steps are required for Tough 1500 Resin V1?

Wash the printed part in IPA, then post-cure for 60 minutes at 70 °C under UV light to achieve full strength and flexibility.
