How much does the Markforged Metal X cost?
Estimated price range
Our best estimate for a metal additive manufacturing in this class — not a quote from Markforged. Configuration moves it a long way.
Overview
The Markforged Metal X prints metal parts by Metal FFF from bound powder filament, in a build volume 300 mm wide, 220 mm deep and 180 mm high. The printer itself is small, 575 mm wide, 467 mm deep and 1120 mm high at 75 kg (165 lbs), but a printed part is not yet a metal part. It still has to be washed and sintered, and the same page lists the two units that do that.
The Wash-1 uses Opteon SF-79 solvent, with a washing time given as 12-72 hrs typical. The Sinter-2 furnace reaches a peak internal temperature of 1,300° C (2,372° F). The quoted Z layer resolution, 85 μm - 170 μm, is stated post-sinter, so it describes the finished part and not the layer as it leaves the nozzle.
Compatible materials are 17-4PH Stainless Steel, Copper, H13 Tool Steel, Inconel 625, and A2 and D2 Tool Steel, supplied as bound powder metal filament on spools. Filament on a spool is handled like any other printer feedstock, which is the practical difference from machines that are loaded with loose metal powder.
Parts can be printed solid or with triangular closed cell infill. Infill cuts the amount of metal in a thick section, and with it the mass that has to pass through the wash and the furnace. The bed is heated and auto leveling, with replaceable print sheets, and the release material is a ceramic that becomes powder during sintering.
The envelope is the main limit. Nothing longer than 300 mm fits, and height stops at 180 mm, so this is a machine for brackets, inserts, nozzles and similar small components.

Strengths & Limitations
Strengths
- Feedstock is bound powder metal filament on spools, not loose powder
- Six listed alloys: 17-4PH Stainless Steel, Copper, H13 Tool Steel, Inconel 625, and A2 and D2 Tool Steel
- Post-sinter Z layer resolution of 85 μm - 170 μm
- Parts can be solid or use triangular closed cell infill to reduce metal in thick sections
- Heated, auto leveling print bed with replaceable print sheets
- The printer weighs 75 kg (165 lbs) and is 575 mm wide by 467 mm deep
Limitations
- Build volume is limited to 300 mm wide, 220 mm deep and 180 mm high
- Every part needs a wash, listed at 12-72 hrs typical, and a sintering cycle before it is usable metal
- The Sinter-2 furnace weighs 350 kg (772 lbs) and the Wash-1 136 kg (300 lbs), so the installation is far larger than the printer
- Washing uses Opteon SF-79 solvent, which has to be stored, handled and disposed of

Frequently Asked Questions
01
In three steps. The printer lays bound powder filament by Metal FFF. The part is then washed in the Wash-1 with Opteon SF-79 solvent, for a time listed as 12-72 hrs typical. Finally it is sintered in the Sinter-2, whose peak internal temperature is 1,300° C (2,372° F).
02
The build volume is 300 mm wide, 220 mm deep and 180 mm high. The layer resolution is quoted after sintering, 85 μm - 170 μm, which signals that the part changes size in the furnace. The table does not give the finished-part envelope, so ask for it if a part is close to the limits.
03
17-4PH Stainless Steel, Copper, H13 Tool Steel, Inconel 625, and A2 and D2 Tool Steel. All are supplied as bound powder metal filament on media spools. A ceramic release material is printed with them and becomes powder during the sintering process.
04
They can be. Internal part geometry is listed as closed cell infill (triangular) or solid parts. Infill reduces the metal in thick sections and the mass that has to be washed and sintered. A solid part is the choice where the full section has to carry load.
05
The printer is 575 mm wide, 467 mm deep and 1120 mm high and weighs 75 kg (165 lbs). The Wash-1 is 609 x 685 x 1,067 mm and 136 kg (300 lbs). The Sinter-2 is 1,200 x 700 x 1,500 mm and 350 kg (772 lbs).
