Formlabs Tough 1500 Resin V2 (1 Liter) - Form Studio 1

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.

This resin is supported on Form Studio 1 and incompatible with Form 4 Generation printers. For Form 4 Generation printers use Tough 1500 (Form 4).

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.

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.

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.

^{*When tested under ASTM D4459 Accelerated indoor aging standard.}

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.

Applications

Tough 1500 Resin V2 is ideal for resilient prototyping or simulating the toughness of polypropylene (PP).

Prototypes requiring the toughness, compliance and resilience of polypropylene.

Tough and rugged enclosures with functional elements like self-tapping screw bosses and snap fits.

Impact resistant jigs and fixtures that survive long term use on the factory floor.

Parts that need a combination of stiffness and ductility to create compliant mechanisms like latches, flexures, and dampers.
