Figure 4 Tough 75C FR Black Resin (1Kg, 9Kg)
NOTE: 9kg option is for the Figure 4 135 ONLY
Figure 4 Tough 75C FR Black is an industry-leading, flame-retardant 3D printing material designed to meet the highest standards in electrical and mechanical performance. With cutting edge UL 94 V0 rating at just 0.4, 0.75 and 3 mm thicknesses, this material ensures outstanding durability, superior electrical properties, and precise fine feature detailing for critical applications. Its ability to achieve UL94 V0 compliance at thicknesses down to 0.4 mm makes it the ideal choice for electrical enclosures, connectors, and RTI-rated components in aerospace, automotive, and industrial applications.
Built for demanding environments, it delivers:
- High-resolution fabrication for intricate components
- Exceptional toughness and flexibility with 7.8% elongation at break
- Outstanding resistance to thermal degradation with RTI Electrical at 150°C and RTI Mechanical at 130°C
- Glow Wire Ignition (GWI) rating of 800°C and Comparative Tracking Index (CTI) of 600V

Whether for low-volume production or functional prototypes, Figure 4 Tough 75FR Black is the only projection-based material to achieve these performance benchmarks, ensuring reliable, high-quality parts for the most demanding industries.
