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.
