The Markforged FX10 is a 122 kg industrial printer for continuous-fibre composites such as Onyx and Nylon White, and, with a separate Metal Kit, for stainless and tool steel. It is for manufacturers that need strong tooling, fixtures and end-use parts.
Does the Markforged FX10 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 FX10
Choose the FX10 when you make jigs, fixtures, tooling or end-use parts that need continuous carbon fibre or metal strength, in a factory that is happy to manage printers in Markforged's Eiger software. SimplyPrint cannot run it through Klipper, OctoPrint or the SimplyPrint Client; the maker's cloud is the only route marked possible. For high-temperature polymers such as PEEK and PEI at a far lower price, look at the Prusa Pro HT90.
Pros
A second nozzle lays continuous carbon fibre into Onyx, Onyx FR, Onyx ESD or Nylon White for what Markforged calls metal-strength parts.
A 375 x 300 x 300 mm volume with a chamber heated to 60 °C and a bed up to 150 °C, so large parts print in one piece.
Low-touch automation: automatic spool changeover, laser-micrometer and vision-based calibration and part inspection, and a build for around-the-clock use (Markforged's claims).
A separately bought Metal Kit swaps the print engine so the same machine prints 17-4 PH and 316L stainless steel and tool steel.
Markforged lists two-factor authentication, encrypted print files, over-the-air updates, and UL, CE and EU Machinery Directive certifications.
Fabbaloo's launch coverage calls it much improved over the Markforged X7 and an impressive machine for industrial production.
Cons
Industrial price: Fabbaloo puts a unit at about US$100,000, and metal printing needs the extra Metal Kit plus Wash-1 debinding and a Sinter-2 furnace run of 26 to 31 hours.
SimplyPrint cannot connect to it through Klipper, OctoPrint or the SimplyPrint Client; only the maker's cloud is marked possible.
Slicing and remote management run in Markforged's cloud-based Eiger software, which some organisations' compliance rules don't allow; Markforged lists two-factor authentication and encrypted print files.
Big and heavy: 122 kg and 760 x 640 x 1,200 mm, so it needs floor space, not a desk.
We found no independent hands-on test, so most performance claims are Markforged's own.
Who it suits
SchoolsNot a good fit
A roughly US$100,000, 122 kg industrial machine with cloud software; at most a university research lab, not a classroom.
HobbyistsNot a good fit
Priced and sized for factories, and SimplyPrint cannot connect to it.
BusinessesGreat fit
Built for aerospace, automotive and tooling work, with continuous fibre, optional metal, a heated chamber and automated calibration.
Print farmsCan work
Designed for low-touch production and fleet management in Eiger, but every machine is a six-figure purchase and SimplyPrint cannot run it.

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 FX10, 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.
Founded:
2013 ·
Headquarters:
Waltham, Massachusetts, US ·
Ownership:
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.

Is the Markforged FX10 compatible with SimplyPrint?
Not yet. The maker's software would allow SimplyPrint to connect to the Markforged FX10, but we haven't built it.
What slicer should I use for the Markforged FX10?
The Markforged FX10 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 FX10 print?
Markforged lists Nylon (PA) and Carbon-fiber & glass-filled for the FX10. It prints only Markforged's own materials.
What is the Markforged FX10's bed size and build volume?
The Markforged FX10 has a 375 x 300 mm print bed and prints up to 300 mm tall, a build volume of about 375 x 300 x 300 mm. See the full specifications table above for bed type, temperatures and more.
