Metal X

The World's #1 Best Selling Metal 3D Printer


Using Markforged's new ADAM technology, the Metal X makes metal 3D printing more accessible than ever before.


  • Range of Materials: 3D print parts in 8 different metals, including titanium.
  • Large Build Volume: Print big with the 300 x 220 x 180 mm (WDH) build volume.
  • Ultra-Fine Resolution: Print fine detail, down to a layer height of 50-microns.
  • Flexibility: Use already installed wash stations and furnaces if available.


To determine how much money your organisation could save with the Metal X, contact our team about a cost benefit analysis.


Please note: You may see the Metal X being advertised elsewhere with a laser inspection tool. This is incorrect, although originally advertised by Markforged when first announced, the Metal X doesn't include the laser inspection tool.

From the company that revolutionised carbon fibre, Kevlar and fibreglass 3D printing comes a new breakthrough in metal 3D printing. The Metal X is a metal 3D printer that utilises a process called ADAM (Atomic Diffusion Additive Manufacturing) to print parts. This process uses metal powder and bulk sintering to create true-to-design solid metal parts, that can be made from a wide range of metals including Titanium 6-4 and 17-4 stainless steel.


The Metal X - The Ultimate Metal 3D Printer

The Metal X has a build volume of 300 mm x 220 mm x 180 mm (WDH) with an enclosed build chamber. It can print down to a layer height of 50-microns, and the user can make use of honeycomb infills and other geometries which would be impossible with subtractive and traditional manufacturing processes.

Atomic Diffusion Additive Manufacturing

3D printing metal parts has never been simpler than with the Metal X. Atomic Diffusion Additive Manufacturing prints your part using a bound metal powder surrounded by plastic. The plastic is then dissolved, and the metal powder sintered. The resulting parts are solid metal, with the same strength and durability as metal parts that have been cast.

Metal X Printed Parts

The Metal X can 3D print several metals, including: 17-4 Stainless Steel, H-13 Tool Steel, 6061 Aluminum (Beta), 7075 Aluminum (Beta), A-2 Tool Steel (Beta), D-2 Tool Steel (Beta), Copper (Beta), IN Alloy (Inconel) 625 (Beta) and Titanium Ti-6Al-4V (Beta). The metals with beta next to them are currently in the last stages of testing, and will be approved for customers soon.

What People Say

“Not only is the material used with the Metal X meant to be safe to handle, but the ADAM process offers design and production advantages that powder bed processes don’t have.”
Michael Molitch-Hou

“If you can afford a half million to million dollar metal printer, buy one. For the rest of the world, this is for you”
–Greg Mark, Markforged CEO

Example Prints

This Ducati Brake level is made of Stainless Steel 17-4. It was printed on the Metal X in a time of 4 hours 45 minutes.

Many 3D printers lay claim to being ‘industrial-grade’ but when you delve into their material list, rarely do you find anything more durable than nylon.

That’s where Markforged 3D printers differ. In the case of the Desktop and Industrial series 3D printers, these use nylon or Onyx as the base material (Onyx is a proprietary filament made by Markforged, it’s part nylon, part chopped carbon fibre). You can then reinforce prints with continuous strands of a stronger composite - carbon fibre, fibreglass, or Kevlar - to create truly industrial-grade prototypes and end-use parts.

For example, parts printed in carbon fibre are stronger than 6061-T6 aluminium. The Desktop series includes the Mark Two, Onyx One and Onyx Pro, and the Industrial series the X7, X5, and X3. There’s a printer for every application.

Then there’s the Metal X, Markforged’s greatest machine yet. This 3D printer utilises a process called ADAM (Atomic Diffusion Additive Manufacturing) to print parts in powdered metal surrounded by a plastic support. The parts are then sintered in a furnace externally to become solid. This enables you to manufacture metal parts with geometries and details that would be impossible with subtractive manufacturing processes.
