Markforged Metal Post-Processing Solutions
Complete the Markforged metal printing workflow with integrated debinding and sintering equipment.
The Markforged Metal 3D Printing Workflow
Metal parts printed on Markforged systems follow a three-step process based on Metal Injection Molding (MIM): print, wash, and sinter.
First, the metal printer produces a “green” part by extruding metal powder bound in a wax and polymer binding matrix. This approach avoids the need for loose powder handling during printing. The printed part is then transferred to the Wash-1 system, where the wax is removed through a controlled chemical debinding process.
After washing, the part moves to the Sinter-2 furnace, where it is heated under controlled conditions to remove the remaining binder and fuse the metal particles into a dense final component.
Markforged post-processing machines are designed for consistent operation in shop environments, and integration with Eiger software to support repeatable part quality.
Note: This workflow is used on systems like the FX10 with the metal printing upgrade (previously offered as the Metal X system bundle).
Markforged Wash-1
The Wash-1 is a solvent-based debinding system that prepares your metal printed “green” parts for the sintering furnace.
During debinding, parts are immersed in a compatible solvent (such as Opteon SF79, Opteon SF80, or Tergo Metal Cleaning Fluid) to remove the wax from the printed material. This step produces a “brown” part with a porous structure, which allows the remaining binder to be removed during sintering.
Separating the debinding and sintering stages helps improve part quality and reduces contamination within the furnace. Proper debinding also supports more consistent shrinkage and final material properties.
The Wash-1 is designed for use in standard shop environments, with ventilation requirements that are typically less intensive than traditional powder-based metal systems.

Markforged Sinter-2
The Sinter-2 is a tube furnace used to sinter metal parts produced through the Markforged metal printing workflow. It converts washed “brown” parts into dense metal components by removing the remaining binder and fusing the metal particles under controlled temperature and atmosphere conditions.
The system features a large, carbon-free retort , allowing it to process a range of part sizes and build quantities from the Metal X and the FX10 once converted to its metal printing capability. This supports both batch production and larger individual components within a single sintering cycle.
The Sinter-2 also includes temperature control systems and safety features such as a mechanical door interlock to support consistent operation. Typical cycle times vary by material and geometry but can be completed within a standard production timeframe.

Frequently Asked Questions (FAQs) About Markforged Post-Processing Machines
What is the Markforged metal 3D printing workflow?
The Markforged metal workflow follows three steps: print, wash, and sinter. A part is first printed as a “green” part using metal powder bound in a wax and polymer matrix. It is then debound in the Wash-1 and sintered in the Sinter-2 to produce a dense metal component.
What does the Wash-1 do in the Markforged metal process?
The Wash-1 removes the wax from the original 3d printed “green” parts using a controlled solvent-based debinding process. This creates a porous “brown” part that allows the remaining binder to be removed during sintering. Proper debinding helps improve final part quality and consistency.
What does the Sinter-2 do in metal 3D printing?
The Sinter-2 furnace converts “brown” parts from the Wash-1 post-processing machine into metal by removing the remaining binder and fusing the metal particles under controlled heat.
Why is debinding and sintering required for Markforged metal parts?
Markforged metal parts are printed using a bound metal filament, which contains both metal powder and a wax and polymer binder. Debinding removes most of the binder, and sintering removes the remainder while fusing the metal particles together. These steps are required to achieve final part density, strength, and material properties.
How are metal parts processed after printing on the FX10 or Metal X?
After printing, parts are first debound in the Wash-1 to remove the wax . They are then transferred to the Sinter-2 furnace, where they are heated to form fully dense metal parts. This process is consistent across FX10 systems with metal capability and the previous Metal X workflow.
