Tough 1500 Resin V2 

Resilient. Ductile. Built to Endure. 

Tough 1500 Resin V2 is engineered for strength, stiffness, and exceptional impact resistance—rivaling the mechanical properties of polypropylene (PP). With 10x higher fracture toughness than its predecessor, this updated formulation is optimized for the Form 4 Series printers to produce tough, reliable parts that don’t crack under pressure.

Key Features 

• Extreme Toughness 

10x higher work of fracture and 3x greater Gardner impact strength compared to V1—ideal for rugged, functional parts.

• Remarkable Ductility 

Elongation at break of 155% and 8,000-cycle Ross flex fatigue resistance enable high-performance snap fits and compliant mechanisms.

• Durable Under Stress 

High creep resistance ensures parts maintain shape with <3% strain under 7 MPa after 2 weeks—perfect for lasting functional use.

• Stands Up to Harsh Environments 

The highest UV and temperature stability among compliant SLA materials, with an HDT of 66 °C and excellent aging performance.

• Biocompatibility Certified 

Safe for applications that require skin contact or meet medical regulatory standards.

Ideal Applications 

• Tough, resilient functional prototypes 

• Rugged enclosures with self-tapping screw bosses and snap fits

• Compliant mechanisms such as latches, flexures, and dampers

• Long-lasting, impact-resistant jigs and fixtures for factory use
