Onyx has a flexural strength of 71 MPa (10.3 ksi). For more information on Onyx material properties, check out the data sheet.
What is the difference between chopped carbon fiber and continuous carbon fiber?
Chopped carbon fiber is what is mixed into Onyx filament giving it high stiffness and strength. Continuous carbon fiber is a reinforcement fiber that can be printed in long strands, creating composite parts many times stronger and stiffer than Onyx.
