Markforged X3

Markforged X3 forms part of the Markforged X Series,  the Industrial Composite 3D Printer Series. The Markforged X3 is available with a Markforged Customer Support Plan.

The Markforged X Series are large format industrial 3D printers designed for producing high-strength parts. With a large build volume of 330mm x 270mm x 200mm, the X Series offers exceptionable capabilities for printing jigs & fixtures, components, prototypes, robotics, custom-fit parts and even end-use, functional parts.

The X series consist of 3 variants:



X7 (formerly known as Mark X)

The Markforged X3 prints high quality parts in Onyx. Onyx is a Nylon embedded with micro carbon-fibres, producing parts with excellent stiffness, high temperature resistance and a matt-black finish.  The industrial 3D printer has a default Z-layer resolution of 100 microns, with the ability to print at 50 microns, producing an excellent quality print. The X3 can also print in Onyx FR, a self-extinguishing, flame retardant material. 

Users can also designate a specific layer at which the Markforged X3 can pause, ideal for embedding components or sensors during the print process. The X Series comes with advanced print software Eiger.
