Onyx FR parts

Markforged Onyx FR Filament 800cm³


Onyx FR is similar in many ways to Markforged Onyx (strong, lightweight, matte finish) but if Onyx catches fire, it will burn. Onyx FR will self extinguish within 10 seconds.


Onyx FR is a V-0 rated flame retardant material designed for industries that often have applications with a higher fire risk such as automotive, defense and aerospace. 


Onyx FR is reinforceable with continuous fibre, such as Kevlar, carbon fibre or high strength, high temp fibreglass for truly industrial applications.


Please note: Onyx FR is compatible with the Markforged Industrial Series of machines only.
