Stratasys F870 Brings Large-Build Industrial FDM to the Factory Floor

Stratasys has launched its first new FDM platform in over three years. The F870 is a large-format industrial 3D printer aimed at automotive, aerospace, and defence manufacturers that need strong, end-use parts rather than prototypes.

What the F870 Actually Delivers

The headline number is the build volume: 1000 x 610 x 610 mm, all inside a fully heated chamber. That is enough space to produce large tooling, fixtures, and manufacturing aids without splitting parts across multiple jobs. The system supports nine materials at launch, including Nylon 12CF, ASA, ABS, and a new FDM ABS Draft (Grey) material. All spools use the same 4,100 cm3 high-capapacity format as the existing F3300, which simplifies inventory management for teams already in the Stratasys ecosystem.

The F870's distinguishing feature is its tool-free print head swap. Users can change between fine-resolution tooling, carbon-fibre composite, or high-speed fixture production modes in minutes. That flexibility means a single machine can handle both delicate prototype builds and heavy production work without downtime for reconfiguration.

Who Is Already Using It

Toyota Production Engineering in Georgetown, Kentucky, and Rivian Automotive in Plymouth, Michigan, have both taken delivery of F870 units. Both companies are using the printers for factory-floor tooling and manufacturing aids. That is a meaningful vote of confidence. When two automotive OEMs install a new printer platform at their production facilities before it officially launches publicly, the system has clearly passed real-world validation.

Stratasys will showcase the F870 at IMTS 2026 in Chicago, September 14-19, at Booth 338460 in the South Hall. The company has not yet disclosed pricing or general commercial availability. Given the F3300's market position, expect the F870 to land well into five figures.

What It Means for Industrial Additive Manufacturing

The F870 fills a gap Stratasys created itself. The company has not released a new FDM machine since the F3300 debuted at Formnext 2023, a span of over 1,000 days. During that period, competitors have pushed further into large-format and composite territory. The F870 is Stratasys' answer, and it arrives at a time when manufacturers are actively re-evaluating their on-shoring and supply-chain resilience strategies.

The new ASA military colours material for Fortus systems also signals that Stratasys expects the F870 to find homes in defence production environments. Mission-specific colour options are not something you add to a product line unless customers are asking for them.
