Onyx FR is a flame-retardant short carbon fiber filled nylon designed for use in applications where parts must resist burning. This aerospace-ready “-A” version comes with lot-level material traceability documentation and passes the test suite necessary for qualification under 14 CFR 25.853 for most 3D-printable parts.

Availability: Please note: Due to Traceability Requirements, orders for Onyx FR-A must be placed separately from other products, as they can only be fulfilled from Markforged’s US offices.
