Markforged's desktop continuous-fiber printer: an enclosed machine that reinforces Onyx or nylon parts with carbon fiber, fiberglass or Kevlar. It is aimed at engineers who want aluminum-strength tools, jigs and fixtures.
Does the Markforged Mark Two 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.

What reviewers say about the Markforged Mark Two
Reviews from people who test printers for a living. We link to them; the opinions are theirs.
3D Printing IndustryRecommended79/100July 12, 2022
Benchmarked the dual-nozzle desktop printer on its own test model and real application parts: it passed every print test and scored 79/100, and carbon fiber raised tensile strength about sixfold. Downsides were manual-only bed leveling, accuracy dropping on larger parts and Eiger hiding some print parameters.
“If you have $19,990 to shell out on a capable piece of kit, we strongly recommend the Mark Two.”
Made with Layers (Thomas Sanladerer) · January 18, 2017
Thomas Sanladerer tests the original Mark Two, which lays continuous fiber inlays together with high-performance nylons to make parts that compete with metal, and asks whether that is too good to be true.
When to choose the Markforged Mark Two
Choose it when you need continuous carbon fiber, Kevlar or HSHT fiberglass reinforcement on a desktop. The Onyx Pro only does fiberglass; if you need a larger bed, laser calibration or automatic leveling, the X7 is Markforged's step up.
Pros
Reinforces parts with continuous carbon fiber, fiberglass, HSHT fiberglass or Kevlar.
Prints Onyx, nylon, Precise PLA and Smooth TPU 95A.
3D Printing Industry's tests found it passed every print test and measured a 6.15x strength gain from carbon fiber.
Fully enclosed, with a 4-inch touchscreen.
Removable print bed that goes back with 10 µm repeatability.
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.
Small build volume of 320 x 132 x 154 mm.
Bed leveling is manual, with three thumbscrews.
Who it suits
SchoolsCan work
Enclosed with a touchscreen, and Markforged targets education, but the cloud-only workflow suits engineering courses more than general classes.
HobbyistsNot a good fit
Built for professionals, with closed firmware and no third-party route.
BusinessesGood fit
3D Printing Industry strongly recommended it for reliable fiber-reinforced parts.
Print farmsNot a good fit
One small bed with manual leveling, and SimplyPrint cannot manage it today.

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:

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 Mark Two compatible with SimplyPrint?
Not yet. The maker's software would allow SimplyPrint to connect to the Markforged Mark Two, but we haven't built it.
What slicer should I use for the Markforged Mark Two?
The Markforged Mark Two 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 Mark Two print?
Markforged lists PLA, TPU & flexibles, Nylon (PA) and Carbon-fiber & glass-filled for the Mark Two. It prints only Markforged's own materials.
What is the Markforged Mark Two's bed size and build volume?
The Markforged Mark Two has a 320 x 132 mm print bed and prints up to 154 mm tall, a build volume of about 320 x 132 x 154 mm. See the full specifications table above for bed type, temperatures and more.
When did the Markforged Mark Two come out?
Markforged launched the Mark Two in February 2016.
