FR OBSIDIAN

As Obsidian™ has quickly become one of our most popular materials, we saw an opportunity to expand the platform to meet growing industry needs. FR Obsidian™ builds on that proven performance by adding flame-retardant capabilities for applications where safety, compliance, and reliability are critical.

Flame-Retardant Nylon Built for Safety-Critical Applications

FR Obsidian™ is a flame-retardant nylon filament engineered to deliver enhanced mechanical performance, consistent print quality, and reliable fire protection for demanding applications. Designed to meet stringent safety standards, it achieves a UL94 V-0 rating at 1.5 mm and a CTI rating of 600V (IEC 60112), ensuring excellent resistance to ignition and electrical tracking.

Validated across both Markforged and open-source printers, FR Obsidian™ provides dependable, repeatable results while maintaining excellent surface finish and dimensional stability. It serves as a true one-to-one alternative to Markforged’s Onyx FR at a better value, making it an ideal choice for engineers seeking performance, safety, and cost efficiency.
