Stratasys F870 Is a Large-Format FDM Printer for Factory Floors

A New Large-Format FDM System From Stratasys

Stratasys has introduced the F870, a large-format FDM 3D printing system aimed at automotive, aerospace, and defense manufacturers that want to move additive manufacturing directly into production. The build volume measures 1,000 x 610 x 610 mm, or about 39.4 x 24 x 24 inches, inside a fully heated chamber that maintains 95 degrees Celsius across the entire build length. Stratasys says that thermal stability outpaces comparable systems and is especially important for keeping large Nylon 12CF parts from warping.

Material options include Nylon 12CF, ASA, ABS-M30, and a newly introduced FDM ABS Draft in gray, alongside breakaway and soluble support materials for complex geometries. The system runs on three interchangeable print heads, so operators can switch between them depending on the job. One head is tuned for fine-resolution work like precision tooling and check gauges. Another is built for carbon-fiber composite parts. The third is designed for faster, high-throughput fixture production. Stratasys says the fastest head can roughly double output speed on ASA material compared to standard FDM printing.

Built for Unattended Production Runs

A regenerative drying system keeps material in optimal condition throughout long runs. The printer is rated for up to two weeks of continuous, unattended operation, a feature aimed at production lines that cannot afford to babysit a print job. Material handling is built around four 4,100 cm3 spools with automatic changeover. That supply setup is shared with Stratasys' larger F3300 system, so manufacturers running both machines can simplify inventory. The F870 itself weighs about 1,800 pounds and measures roughly 69 x 49 x 77 inches, with a maximum build diagonal of 46.1 inches.

Stratasys is pitching the system as a direct replacement for outsourced CNC-machined or welded tooling. Specific use cases include end-of-arm tooling for robotics, where lightweight Nylon 12CF parts can cut robot payload and speed up cycle times. Other applications are ergonomic aids, lift assists, drill guides, alignment jigs, and protective housings. One example the company will display at IMTS is a heat shield gripper tool built for robotic end-effector use.

The F870 will have its full public unveiling at IMTS 2026, running September 14 through 19 in Chicago, where it will be on display at Stratasys' booth 338460 in the South Hall alongside other new manufacturing-focused technology.
