# Markforged Onyx Pro: specs, SimplyPrint compatibility and setup > **Possible, not built yet**. The maker's software would allow it, but we haven't built it. If enough people want it, we will. - By Markforged, USA - Launched November 2016 - Canonical page: https://simplyprint.io/compatibility/markforged-onyx-pro ## Markforged Onyx Pro at a glance Markforged's entry fiber printer: a desktop machine that prints Onyx and reinforces it with continuous fiberglass. It is for teams that want stronger prototypes, tools and fixtures than plain plastic gives. - Build volume: 320 x 132 x 154 mm - Enclosure: Fully enclosed - Motion system: Other kinematics - Prints well: PLA, TPU & flexibles, Nylon (PA), Carbon-fiber & glass-filled - Connectivity: Wi-Fi ## Connect the Markforged Onyx Pro to SimplyPrint | Way of connecting | Status | What you need | Notes | | :--- | :--- | :--- | :--- | | The maker's cloud | Possible, not built yet | | Cloud-only printer: it prints from Markforged's Eiger platform, which has an API.

Filament compatibility for the Markforged Onyx Pro: the materials Markforged lists for it. It prints only Markforged's own materials. | Filament | Suitability | Notes | | :--- | :--- | :--- | | PLA | Great | On the maker's list of materials for this printer. | | PETG | Not ideal | Not on the maker's list, and this printer prints only the maker's own materials. | | TPU & flexibles | Great | On the maker's list of materials for this printer. | | ABS & ASA | Not ideal | Not on the maker's list, and this printer prints only the maker's own materials. | | Nylon (PA) | Great | On the maker's list of materials for this printer. | | Polycarbonate (PC) | Not ideal | Not on the maker's list, and this printer prints only the maker's own materials. | | Carbon-fiber & glass-filled | Great | On the maker's list of materials for this printer. | ## When to choose the Markforged Onyx Pro Choose it when fiberglass reinforcement is enough. If you need carbon fiber, Kevlar or HSHT fiberglass, take the Mark Two, which is the same size; for a larger bed and automatic calibration look at the X7. ### Pros - Reinforces Onyx parts with continuous fiberglass; Markforged says they are 10x as strong as traditional printing plastics. - Prints Onyx, Precise PLA and Smooth TPU 95A. - Aluminum unibody frame and a removable bed with 10 µm repeatability. - Same 320 x 132 x 154 mm build volume as the Mark Two. ### 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. - Fiberglass is the only continuous fiber; carbon fiber and Kevlar need the Mark Two. - Small build volume and manual shim leveling. ### Who it suits - Schools: Can work. A desktop machine for engineering courses, but it is cloud-bound and sold to professionals. - Hobbyists: Not a good fit. Built for professionals, with closed firmware and no third-party route. - Businesses: Good fit. Fiberglass-reinforced prototypes and tooling on a desktop. - Print farms: Not a good fit. One small bed with manual leveling, and SimplyPrint cannot manage it today. ## Printers like the Markforged Onyx Pro that work with SimplyPrint - [Creality CR-200B](https://simplyprint.io/compatibility/creality-cr-200b): Compatible, 200 x 200 x 200 mm, Similar build volume · Also prints Nylon (PA) - [Wanhao D6 Plus](https://simplyprint.io/compatibility/wanhao-d6-plus): Compatible, 200 x 200 x 175 mm, Similar build volume · Also prints Nylon (PA) - [QIDI X-Smart 3](https://simplyprint.io/compatibility/qidi-x-smart-3): Compatible, 175 x 180 x 170 mm, Similar build volume · Also prints Nylon (PA) - [Kingroon KLP1](https://simplyprint.io/compatibility/kingroon-klp1): Compatible, 210 x 210 x 210 mm, Similar build volume · Also prints Nylon (PA) ## About Markforged 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 - Website: https://markforged.com Openness: Walled garden (1.3 of 5) Closed by design: proprietary firmware, Markforged-only materials and cloud slicing, for industrial buyers who want one supported, secure system. - Firmware and custom firmware (1 of 5): Closed firmware, updated over the air through Eiger; no source is published and no custom firmware is supported. - Local control and integrations (1 of 5): 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. - Third-party filament, slicers and parts (1 of 5): Markforged printers use only Markforged materials (Onyx, continuous fibres, metals) and only Eiger for slicing. - Repairs and spare parts (2 of 5): 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. - Data and privacy (3 of 5): 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. ### 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. - April 25, 2025: Nano Dimension completed its acquisition of Markforged, valued at $116 million ($5.00 per share). - 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. - April 2024: A Delaware jury found that Markforged infringed a Continuous Composites patent on continuous-fibre printing; Markforged attempted to appeal before settling. - November 2023: Markforged announced a restructuring, mostly an approximately 10% headcount reduction, citing continuing economic headwinds. - 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.
