SLA | Stiff & Strong | Heat Resistant | Robust | Low Creep | UL94 VO Certified
Produce certified flame retardant, UL 94 V-0 and FAR-rated 3D printed parts
Flame Retardant Resin is a specialty UL 94 Blue Card certified material for creating self-extinguishing and halogen-free parts with favorable flame, smoke, and toxicity (FST) ratings. Use FR Resin to easily 3D print flame retardant, heat-resistant, stiff, and creep-resistant parts that will perform well long-term in indoor and industrial environments with high temperatures or ignition sources.
Tests and certifications include: UL 94 V-0 at 3 mm thickness for flammability; FAR 25.853 Appendix F, Part I for flammability; and ASTM E662 for FST. For full test results and certifications, see the Technical Data Sheet.
Accelerate time to market without the design constraints and upfront costs of traditional manufacturing with isotropic and highly detailed parts (XY resolution: 25um) with unlimited geometric freedom in any quantity (from 1 to 1000 parts) at any time.
Applications
Flame Retardant (FR) Resin is a cost and time-effective solution for fabricating self-extinguishing parts.
Consider Flame Retardant Resin for:
- Interior parts in airplanes, automobiles, and railways with excellent surface finish
- Protective and internal consumer or medical electronics components
- Custom jigs, fixtures, and replacement parts for industrial environments with high temperatures or ignition sources
