The Markforged Onyx filament material is at the heart of all Markforged 3D printers. It is a beautiful black filament made of durable nylon / PA6 with micro-carbon fibres. This provides rigid and dimensionally stable parts which are 1.4 times stiffer than ABS thermoplastics (plastics). Onyx parts achieve a high surface quality, chemical resistance and heat tolerance. Items such as jigs and fixtures, robot grippers and soft jaws for machine vices are popular with this robust material.

The printing of high amounts of onyx filament can alter the physical composition of the printhead. This means the printhead will become more suited to onyx than nylon after continued use. You are of course free to swap between onyx and nylon at will, however it is our recommendation that if you want to continue using both materials, you should buy a second printhead for your printer.
