Key Features of the X3 3D Printer:

Onyx Filament

Onyx Filament can be used for anything from tooling to end-use parts. This nylon is mixed with chopped carbon fiber to give both high strength and heat deflection up to 293 degrees Fahrenheit. Parts printed with this material will also have an excellent surface finish.


The Onyx parts printed on the X3 Industrial 3D printer are 20% stronger and 40% stiffer than ABS parts. They stand up to abuse - resistant to impact and a variety of manufacturing chemicals.


Markforged developed its Eiger software to make 3D printing simple. Easily import, manipulate and slice your 3D models directly in a web browser with this cloud-based software that comes with every printer. Printers from Markforged also have built-in touchscreens to help you connect to Wi-Fi, start parts and manage your printer with ease.
