On September 9, 2026, Stratasys announced the F870, a large-format FDM printer built for factory-floor tooling, fixtures, and manufacturing aids. Toyota Production Engineering in Georgetown, Kentucky, and Rivian Automotive in Plymouth, Michigan, already have units installed ahead of commercial availability. The headline number is a 1000 x 610 x 610 mm build volume (39.4 x 24 x 24 inches) inside a fully heated chamber, which Stratasys calls the longest heated build capacity in its class. Here is what the machine actually does, and what it means for anyone who needs a big ABS, ASA, or carbon fiber nylon part that does not warp.
What Stratasys announced with the F870
According to the Stratasys press release and VoxelMatters' September 10 coverage, the F870 offers 372,000 cubic centimeters of build capacity and a maximum diagonal build length of 1,171 mm. The chamber holds 95 degrees Celsius throughout the build, and the machine includes a regenerative drying system for filament storage, so the material stays dry from canister to nozzle.
Nine materials ship at launch: FDM Nylon 12CF (carbon fiber reinforced nylon), ABS-M30 in black, ASA in six colors, the new FDM ABS Draft in gray, and SR-35 soluble support. Three interchangeable print heads trade resolution for speed, from the N14 at about 25 cubic centimeters per hour for precision gauges up to the N25 at up to 66 cubic centimeters per hour for big ASA fixtures. Four 4,100 cubic centimeter spools with automatic changeover support up to two weeks of unattended printing. Stratasys will show it publicly at IMTS 2026 in Chicago, September 14 through 19, Booth 338460.
Why the heated chamber is the whole story
Big build volume gets the attention, but the heated chamber is what makes that volume usable. ABS, ASA, and nylon all shrink as they cool, and on a one meter fixture that shrink adds up across every layer. Without a hot chamber, the bottom layers pull inward while the top layers are still going down, and the part lifts at the corners, cracks between layers, or comes out with a bow you cannot fixture around.
A chamber that stays hot keeps the whole part warm while it prints, so the layers bond and the stress relaxes instead of accumulating. That is why industrial FDM machines have always been enclosed and heated, and why the F870's launch materials are engineering polymers rather than PLA. It is the same physics we deal with daily at our Rockville, MD shop, where enclosed, heated-chamber printers handle ABS, ASA, carbon fiber blends, PCTG, and PEEK.
My large ABS fixture keeps warping and cracking on my printer. What am I doing wrong?
Your part is cooling unevenly while it prints, so the fix is to control the ambient temperature around the part: enclose the printer, let the chamber heat-soak before starting, kill part cooling fans, and add a brim or mouse ears at the corners. Warping is not a filament defect and it is rarely a bed adhesion problem alone. It is thermal contraction fighting the bond to the bed, and the bigger the part, the more contraction there is to fight.
Enclose the machine and let the air inside get hot before the first layer goes down. Turn the part cooling fan off or nearly off for ABS and ASA. Use a wide brim, and consider splitting a long part into sections with alignment features, since a 300 mm section warps far less than a 900 mm one. Dry your filament; wet nylon in particular prints weak and rough. If the part still fails, the geometry is simply too large for your enclosure, and that is where a heated-chamber machine or a service shop that runs one comes in.
I need one big jig printed in ABS or carbon fiber nylon, not a whole machine. Can someone 3D print it for me?
Yes. Send us a STEP or STL file, or the physical part to scan, and we will print your jig, fixture, or bracket in ABS, ASA, or a carbon fiber reinforced material in a heated-chamber printer, with no minimum order and shipping from Rockville, MD. Most shops that need one large fixture do not need a factory-floor printer sitting next to it. They need the part, correctly oriented, in a material that holds its shape on the job.
We orient every part around its load path, favor perimeters over infill for stiffness, and split oversized geometry into keyed sections when that gives a straighter, stronger result. If your fixture sees heat, chemicals, or sustained load beyond what ABS or nylon can handle, our PEEK and ULTEM printing service covers the high-temperature end.

What this means for makers and engineering buyers
For makers: the F870 is not a desktop purchase, but its design confirms what your warped prints have been telling you. Engineering polymers want a hot, still chamber and dry filament. If you are fighting ABS on an open-frame machine, an enclosure is the highest-return upgrade you can make.
For engineering buyers: Toyota and Rivian putting this machine on the floor for tooling and manufacturing aids is a signal that printed fixtures, assembly tools, and inspection gauges are now a normal way to skip machining lead times. Large, one-off, and needed this month is exactly the profile where a print beats a machined billet, whether it comes off your own machine or ours.
If your company makes engineering filaments, dryers, or enclosure hardware and wants an independent look at how they perform on real parts in a working shop, we are open to reviewing products. Reach us at info@dcadditivepros.com.
Frequently asked questions
Why does my ABS 3D print warp and how do I stop it?
ABS shrinks as it cools, so the bottom of the part pulls inward while the top is still being printed. Enclose the printer, let the chamber heat up before printing, turn off part cooling, and add a brim. For large parts, a fully heated chamber is the real fix.
Can I 3D print a fixture or jig instead of machining it?
Yes, for most tooling, fixtures, assembly aids, and inspection gauges. Printed in ABS, ASA, or carbon fiber nylon and oriented for the load, a fixture is usually ready in days rather than the weeks a machined one takes.
What size part can be 3D printed in one piece?
It depends on the machine. Desktop printers top out around 250 to 350 mm, while industrial systems like the newly announced Stratasys F870 reach 1000 x 610 x 610 mm. Larger parts are often split into sections with keyed joints and bonded.
Where can I get a large carbon fiber nylon part printed near Washington, DC?
DC Additive Pros in Rockville, MD prints ABS, ASA, carbon fiber reinforced materials, PCTG, and PEEK in heated-chamber printers, with no minimum order. Email info@dcadditivepros.com with a file or a photo of the part.
