Formlabs Tough 1500 Resin v2

Tough 1500 Resin V2 is a resilient material with strength, stiffness, and toughness comparable to polypropylene (PP), offering exceptional resistance to fractures, impacts, and shattering.

Create parts that balance stiffness and ductility, whether for compliant mechanisms or rugged enclosures with self-tapping screws and snap fits. Tough 1500 Resin V2 enables a wide range of applications, from functional prototypes to end-use jigs and fixtures.

Tough 1500 Resin V2 is a new material formulation that leverages the Form 4 Series to deliver 10 times higher fracture toughness than the previous version.

Why Choose Tough 1500 Resin v2?

Robust, resilient and ductile material that rivals the toughness of polypropylene.

Tougher Where It Matters 10 times higher work of fracture, so parts don’t fail when drilled, tapped, or cracked. Three times higher Gardner impact strength for thin walls that don’t shatter. High Environmental Stability for Demanding Applications The highest temperature and UV resistance (66 °C HDT and ~30.4% EAB* after 400 hours accelerated aging) of any high-compliance (>100% EAB) SLA material. Ductile and Resilient for Long-Lasting Compliant Parts Extremely high elongation at break (155%) and Ross flex fatigue (8,000 cycles) for features like snap fits and compliant mechanisms. Tough Parts That Don’t Deform Over Time High creep resistance matching polypropylene, with less than 3% strain under 4 MPa load after 2 weeks.
