Stratasys F870 Brings Large-Format FDM to Factory Floors

The F870 is Stratasys' biggest FDM printer yet

Stratasys has launched the F870, a large-format fused deposition modeling system aimed at factory-floor tooling, manufacturing aids, and end-use parts. At 1000 x 610 x 610 mm, it has the longest heated build volume in its class, and Toyota and Rivian have already installed units at their Georgetown, Kentucky and Plymouth, Michigan facilities.

That is notable because industrial FDM has mostly lived in the prototyping corner. Stratasys wants to move it into production support: jigs, fixtures, gauges, and replacement parts printed on demand rather than ordered and waited for. The F870's build chamber holds 372,000 cubic centimeters and stays at a steady 95 degrees Celsius. Four 4,100 cubic centimeter material spools with automatic changeover can keep it running unattended for up to two weeks.

Three print heads cover different jobs

The machine ships with three interchangeable N-series print heads. The N14 handles precision work at 0.18 to 0.33 mm layer resolution and prints at up to 25 cubic centimeters per hour, ideal for check gauges and detailed tooling. The N20H runs at 0.25 mm for Nylon 12CF and structural fixtures. The N25 goes faster at 0.33 mm, up to 66 cubic centimeters per hour, for large ASA parts.

Nine materials are available at launch, including Nylon 12CF, ABS-M30 Black, ASA in six colors, and a Draft Gray formulation arriving in the third quarter. Soluble SR-35 support material is included. The printer runs on standard three-phase 208-volt, 30-amp power and uses a built-in vacuum pump instead of external shop air.

Why Toyota and Rivian said yes

Dallas Martin, Additive Manufacturing Engineer at Toyota North America, put it plainly: "We have already seen the value Stratasys additive manufacturing can deliver. The next challenge is expanding its use across more applications. The F870's combination of build size, material performance and industrial features aligns with the kinds of manufacturing needs we are looking to address."

Rivian confirmed similar use cases at its Plymouth facility. Both companies are early adopters, not pilot participants, which suggests Stratasys negotiated commercial deployments rather than research loans.

Software and factory integration

The F870 runs GrabCAD Print software and supports MTConnect connectivity for factory-floor integration. Print head replacement is tool-free, and the consumable spool platform is shared with the F3300, so existing Stratasys users do not need entirely new supply chains. The printer debuts publicly at IMTS 2026 in Chicago, September 14-19, Booth #338460.

The F870 does not solve every manufacturing problem, but it does close a gap Stratasys has left open for years: a credible large-format FDM option for companies that already trust the brand and want to print bigger parts without switching to a completely different process.
