The Metal X System is an accessible way to fabricate complex metal parts in a wide variety of advanced metals.


X System

An accessible end-to-end metal 3D printing solution for functional metal parts, next-day.

Simple, Yet Powerful

The Metal X is one of the most intuitive metal 3D printers available today. Print a wide range of materials from stainless steels to copper with minimal training on a closed workflow. Scaling up capacity is easy; just add printers.

Safe and Affordable

The Metal X is designed to be safe to use and accessible for all fabricators. It costs several times less than DMLS metal 3D printing systems and requires no dedicated operator, no powder management system, and minimal PPE.

Quality Parts, Fast

The Metal X is purpose-built for consistent part quality and a seamless user experience. Markforged combines superb software, materials research, and an advanced motion system to deliver industrial-grade parts quickly and reliably.

From design to fully functional metal parts in as few as 28 hours.

Metal X Printer

The Markforged Metal X is a new kind of metal printer. By printing metal powder bound in a plastic matrix, Markforged has eliminated many of the safety risks associated with traditional metal 3D printers. That means no loose powder, no lasers, and none of the traditional safety precautions. It’s safe to use in a shop environment with minimal facility upgrades. In practice, the Metal X is essentially a very advanced FFF 3D printer. Featuring a precision machined gantry, a heated chamber and print bed, and advanced extrusion hardware, the Metal X is equipped to reliably print you durable parts. It is intentionally designed, with wear components and consumables — including print sheets, nozzles, and brushes — accessible and trivial to swap.

Sinter-2 and Sinter-1

The Markforged Sinter-2 and Sinter-1 are highly optimized tube furnaces used for sintering 3D printed metal parts. They provide leading edge sintering reliability and run times and are equipped with advanced safety features. The Sinter-2 is more advanced than the Sinter-1 — featuring a larger working volume, more precise temperature control, and a mechanical door interlock. The Sinter-1 and Sinter-2 typically have run times between 26 and 31 hours. However, the Sinter-2 can process small parts in express mode, where it can sinter up to 250g of parts in just 17 hours.


The Wash-1 is a solvent-based debinding system. It primarily uses Opteon SF-79, a high-performance fluid designed to offer superior cleaning power, higher efficiency, and safety in an environmentally sustainable way — Opteon SF-80 or Tergo Metal Cleaning Fluid can be substituted if needed. The Wash-1 operates with simple ventilation and features an extremely simple user experience. It’s been tested and verified as a shop-safe system.
