Why Choose UL 94 for Industrial Manufacturing?
UL94 Flame Retardant Resin is a high-performance technical photopolymer engineered for projects where industrial safety is non-negotiable. Boasting a UL94-V0 flammability rating, this material provides a critical self-extinguishing capability, stopping combustion within seconds once the flame source is removed. Manufactured via precision SLA and DLP 3D printing, it is the go-to solution for aerospace, mass transit, and high-voltage electronics to prevent flame propagation and ensure structural integrity.
Advantages
Certified Fire Safety: Full compliance with UL94-V0 standards prevents the spread of fire.
Superior Dielectric Properties: High resistance to electrical tracking, making it safe for PCB housings and connectors.

UL94 Material FAQ
What does the UL94-V0 rating signify in 3D printing?
The V0 rating is the highest safety standard indicating the material self-extinguishes within 10 seconds during a vertical burn test and produces no flaming drips.
Can flame-retardant 3D printed parts be painted?
Yes. However, to maintain the material’s safety certification, it is recommended to use specialized flame-retardant coatings that do not compromise its properties.
Which industries mandate the use of UL94 certified materials?
It is required for aerospace interior components, rail transit equipment, electrical distribution panels, and battery enclosures where fire risks are high.
Is this material resistant to outdoor environmental conditions?
The material is chemically stable, but due to its photopolymer nature, UV-resistant coatings are recommended for prolonged outdoor use to prevent aging.
Is flame-retardant resin cost-effective for low-volume production?
Yes. For batches of 1-500 units, it is highly cost-effective as it eliminates tooling costs while delivering injection-molding quality finishes.
What is the Heat Deflection Temperature (HDT) of this material?
Flame-retardant resins typically offer an HDT between 70°C and 90°C, providing sufficient stability under moderate thermal and mechanical loads.
