Markforged's industrial continuous-fiber printer: a 330 x 270 x 200 mm bed, a laser for inspection and bed leveling, and the full range of Markforged fibers. It targets production-floor jigs, fixtures and end-use parts.
Does the Markforged X7 3D printer work with SimplyPrint, OctoPrint, Mainsail and Fluidd?
Each way of connecting it, what it needs, and how to set it up.
The maker's cloud
Possible, not built yet
Cloud-only printer: it prints from Markforged's Eiger platform, which has an API. SimplyPrint can build support through that API if enough people vote for it.

Tip: this is a general guide from the printer's specs - always check your filament's recommended settings. With SimplyPrint you can save a profile for each spool and track exactly what filament you have in stock.
When to choose the Markforged X7
Choose it when you want continuous carbon fiber, fiberglass or Kevlar parts on a production floor without a heated chamber. The Mark Two is the desktop option but has a smaller bed and manual leveling; the FX10 adds a heated chamber and a larger bed; the FX20 is the one for ULTEM.
Pros
Laser handles in-process inspection, active calibration and bed leveling.
Prints Onyx, Onyx FR, Onyx ESD, nylon, Precise PLA and Smooth TPU, plus carbon fiber, fiberglass, Kevlar and HSHT fiberglass.
Larger bed than the desktop series: 330 x 270 x 200 mm.
Turbo Print mode is Markforged's fastest, and the Blacksmith adaptive manufacturing option is available only on the X7.
Runs on standard mains power at 150 W and weighs 48 kg.
Cons
Not supported by SimplyPrint yet: it can be built on Markforged's cloud API if enough people vote for it.
Runs Markforged's closed firmware with Eiger, so there is no OctoPrint or Klipper route.
No heated chamber, so high-temperature plastics such as ULTEM need the FX20.
Blacksmith is an additional purchase.
Who it suits
SchoolsNot a good fit
Industrial machine tied to Markforged's cloud; the Mark Two is the more sensible desktop pick for teaching.
HobbyistsNot a good fit
Built for production use, with closed firmware and no third-party route.
BusinessesGreat fit
Industrial fiber-reinforced printing with inspection and calibration built in.
Print farmsCan work
Eiger manages fleets of Markforged printers, but SimplyPrint cannot manage the X7 today.
Printers like the Markforged X7 that work with SimplyPrint
Printers from the same maker, of a similar size, printing the same engineering materials or multi-material like it, that you can buy today and that we know work with SimplyPrint.
Who makes the Markforged X7, and how open Markforged leaves you: whether its printers run without its cloud, take any filament and slicer, and can be repaired. Each area is rated from public sources.

Markforged is an American maker of industrial 3D printers, founded in 2013 near Boston, known for nylon parts reinforced with continuous carbon fibre and for metal printing. Printers, materials and its cloud software Eiger are sold together as one closed platform to manufacturers, defence and aerospace. Nano Dimension bought it in April 2025, and in May 2026 agreed to sell it to Stratasys.

Subsidiary of Nano Dimension since April 2025; sale to Stratasys agreed in May 2026, still pending in August 2026 ·

Closed by design: proprietary firmware, Markforged-only materials and cloud slicing, for industrial buyers who want one supported, secure system.
Firmware and custom firmware ●●●●●
Closed firmware, updated over the air through Eiger; no source is published and no custom firmware is supported.
[2]
Local control and integrations ●●●●●
Markforged printers are sliced and run through Eiger, its cloud software, by default, and Eiger is the only slicer they accept. Sites that cannot use the cloud can pay for Offline Eiger, which works over USB or a private network. APIs for linking other enterprise systems come with Eiger Fleet, a paid cloud subscription. We found no local interface for other software.
[2][6][16]
Third-party filament, slicers and parts ●●●●●
Markforged printers use only Markforged materials (Onyx, continuous fibres, metals) and only Eiger for slicing.
[2][3]
Repairs and spare parts ●●●●●
Replacement print heads, extruders and nozzle parts are sold through Markforged resellers, mostly as assemblies (a Mark Two print head lists at over 1,400 pounds), and some come free under service ('Success') plans.
[13][14]
Data and privacy ●●●●●
Eiger accounts hold your parts library and print jobs on AWS, encrypted, with two-factor login and ISO 27001 certification, and the privacy policy says what is collected. Offline Eiger keeps the data on site.
[4][5][2][6]
Pros
Prints parts reinforced with continuous carbon fibre, Kevlar or fibreglass, strong enough to replace some machined parts.
One supported system: printers, materials and software from one company, with ISO 27001 certification.
Offline Eiger available for sites that cannot use the cloud.
The FX10 prints both composites and metal.
Cons
Only Markforged materials and the Eiger slicer; no third-party filament.
Cloud first: the offline option is a separate subscription.
Ownership in flux: bought by Nano Dimension in 2025, with a sale to Stratasys pending in 2026.
Layoffs in 2023 and a $25 million patent settlement in 2024.
Track record
May 27, 2026: Stratasys agreed to buy MarkForged, Inc. from Nano Dimension for $42.5 million in cash; Nano Dimension keeps the metal binder jetting line. Closing was expected in the second half of 2026, and Stratasys still called it pending in August 2026.
[9][10]
April 25, 2025: Nano Dimension completed its acquisition of Markforged, valued at $116 million ($5.00 per share).
[8]
September 2024: Markforged settled Continuous Composites' patent suit, filed in 2021, by agreeing to pay $25 million over four years, with cross-licences; neither side admitted liability.
[11][12]
April 2024: A Delaware jury found that Markforged infringed a Continuous Composites patent on continuous-fibre printing; Markforged attempted to appeal before settling.
[12]
November 2023: Markforged announced a restructuring, mostly an approximately 10% headcount reduction, citing continuing economic headwinds.
[7]
September 2022: Markforged said its Offline Eiger subscription, which runs fully offline, had received a year of quarterly updates with the same materials and features as the cloud version.

Not yet. The maker's software would allow SimplyPrint to connect to the Markforged X7, but we haven't built it.
What slicer should I use for the Markforged X7?
The Markforged X7 prints only from Markforged's own slicer, Eiger, so none of the slicers in SimplyPrint's cloud can slice for it.
What filament can the Markforged X7 print?
Markforged lists PLA, TPU & flexibles, Nylon (PA) and Carbon-fiber & glass-filled for the X7. It prints only Markforged's own materials.
What is the Markforged X7's bed size and build volume?
The Markforged X7 has a 330 x 270 mm print bed and prints up to 200 mm tall, a build volume of about 330 x 270 x 200 mm. See the full specifications table above for bed type, temperatures and more.
