The Metal X

Production 3D Printer

The Metal X by Markforged greatly accelerates innovation, delivering metal parts overnight using a new technology at a fraction of the cost. Create anything from industrial replacement parts to injection moulds to working prototypes with Markforged Metal X.

Say Hello to ADAM

Atomic Diffusion Additive Manufacturing

ADAM prints your part using a bound metal powder rod that transforms into a dense metal part in one easy step. Bulk sintering provides crystal growth through all axes giving your parts excellent mechanical properties in all directions. ADAM also enables the creation of unique geometries such as closed-cell honeycomb infill.


Why choose the Metal X?

  • It gives you the ability to quickly change your material (for example: from stainless steel to titanium)
  • There are no powder health and safety issues with the metal and wax cord mix.
  • The price point of this system is less than £90,000

303 stainless steel is great for post processing in CNC milling and turning operations. It maintains corrosion resistance up to 800C. We use it in on the drive roller for our fiber system on the Mark X.

17-4 stainless steel combines high strength, corrosion resistance, and hardness, making it widely used in aerospace, medical and petroleum industries. We use it for assembly fixtures and tooling on the Mark X.

As a general purpose aluminum, 6061 combines good machinability, strength, and weldability. It can additionally be anodised with a good finish. We use it for many of the machined components in the Mark X.

7075 Aluminum is one of the strongest aluminum alloys. With good fatigue strength and a high strength-to-weight ratio, this alloy is stronger than common structural steels (A36, 1018). We use it on the kinematic coupling in the bed of the Mark X. It’s also common in aerospace and automotive racing.

A-2 tool steel is air-hardened with excellent impact resistance. We use it for punches, dies, and form tooling on the Mark X.

The high carbon and chromium content of D-2 tool steel provides great hardness and abrasion resistance (but not as tough as A-2). D-2 is often used for cutting tools.

Bearing the highest strength-to-weight ratio of any metal, Titanium 6-4 is ideal for lightweight applications and has both high tensile strength and fatigue resistance. This bio-compatible material is widely used in medical applications such as orthopedic joint replacements.
