Anycubic Kobra S1 Max Fully-Enclosed CoreXY 3D Printer

Product Summary

The Anycubic Kobra S1 Max is a fully-enclosed CoreXY FDM 3D printer for makers who need large-format volume without giving up speed. Its 350x350x350 mm build space takes single-piece helmets, footwear, enclosures and functional parts, so there are no split models or glued seams. Active 65°C chamber heating, a 350°C hotend and a 120°C PEI bed support engineering materials including ABS, ASA, PC, PA and carbon-fiber blends. Motion is rated at a recommended 300 mm/s and a maximum 600 mm/s, with LeviQ 3.0 auto-leveling handling first-layer setup. The machine weighs 25.7 kg, and the multicolor system is sold separately.

Highlights

Large-Format Prints Straight Off The Plate

The 350x350x350 mm build space lets you print helmets, footwear, drone frames and enclosures as a single piece, so you skip splitting models and gluing seams. Large parts come off the plate already functional, which matters when your workshop desk can only hold one machine.

Fully-Enclosed CoreXY With A Heated Chamber

A rigid all-metal CoreXY frame with an enclosed chamber holds the interior at actively heated 65°C, reducing warping on ABS, ASA and nylon. Wider-spaced X-axis linear rods, dual symmetric Y belts and 10mm reinforced Z rods keep large prints stable across the full bed, so tall models stay square.

High-Temperature Path For Engineering Filaments

The 350°C hotend, hardened steel nozzle and titanium-alloy throat tube work alongside a 120°C PEI spring-steel bed, so PC, PA6-CF and PET-CF print without clogging. Carbon-filled materials are handled by a hardened steel extruder gear on a short-distance extrusion path, which keeps feeding consistent during long engineering jobs.

Fast CoreXY Motion With Tuned Limits

Motion is rated at a recommended 300 mm/s and a maximum 600 mm/s, with acceleration set to 10,000 mm/s² as standard and 20,000 mm/s² when needed. Flow dynamics calibration and vibration compensation trim extrusion and ringing, so high speed does not cost surface quality on tall, detailed models.

Auto-Leveling First Layers And Resilient Runs

LeviQ 3.0 measures 49 points across the whole bed, corrects horizontal deviation and levels automatically, then identifies the model and its print area before starting. Object-skip and area leveling let you ignore failed regions instead of reprinting an entire plate of parts, while filament detection and power loss resume protect long runs.

Dual-External Circulation Cooling Against Stringing

Instead of recycling hot air inside the case, two external circulation fans pull room air straight into the chamber, so molten filament solidifies almost instantly. That rapid cooling limits stringing and warping on materials like PETG, while steady throat-tube temperatures against the 350°C hotend keep long prints clog-free.

Noise Figures And Smart Print Monitoring

Standard mode runs at 48 dB or less and quiet print mode at 45 dB, but the level rises to 55 dB when chamber heating is enabled, measured by Anycubic Lab at one meter. A built-in 720P camera with AI spaghetti detection flags failures early and alerts you through the Anycubic app.

FAQ

Which filaments can the Kobra S1 Max print with?
ABS, ASA, PC, PA, PA6-CF, PC-CF/GF and PET-CF for engineering parts, plus PLA, PETG, PET, PLA-CF, PETG-CF and PVA for everyday printing. The hotend peaks at 350°C, the bed at 120°C and the chamber at an actively heated 65°C.

What are the machine dimensions and the print volume?
The machine measures 502.7 x 483 x 584 mm and the print volume is 350 x 350 x 350 mm, so large parts such as helmets and enclosures print as one piece rather than as split sections that need gluing.

How many colors can it print?
Up to 16 colors when paired with the Anycubic ACE 2 Pro color system. The ACE 2 Pro is not included in this standalone printer package and is sold separately, so out of the box the machine prints single-color jobs.

Is it compatible with the ACE Pro color module?
No. The official compatibility statement is that this model does not support the ACE Pro used on earlier Kobra printers, so the ACE 2 Pro is the color system to plan for if you want multicolor output.

Which nozzle sizes are supplied or supported?
A 0.4 mm hardened steel nozzle is pre-installed and an extra 0.6 mm hardened steel nozzle ships in the box. Optional 0.25 mm brass and 0.8 mm hardened steel nozzles are also supported, and the quick-release hotend lets you swap it without tools.

Does the touchscreen offer other languages?
Yes. The interface supports English, Chinese, German, French, Italian, Spanish, Russian, Japanese, Korean and Portuguese, selected directly on the 4.3-inch capacitive screen.

Important Notes

• This listing is the printer only. Multicolor printing requires the Anycubic ACE 2 Pro, sold separately, and 16-color output requires more than one unit.
• The ACE Pro color module from earlier Kobra printers is not supported by this model.
• Active filament drying is not supported on the Kobra S1 Max.
• The 600 mm/s speed, 20,000 mm/s² acceleration and the 350°C, 120°C and 65°C figures are maximum hardware ratings; recommended values are lower.
• Noise is measured by Anycubic Lab at one meter in front of the printer: 48 dB or less in standard mode, 45 dB in quiet print mode, and 55 dB with chamber heating enabled. Individual units vary.
• Select the standard or EU plug variant when ordering; printing performance is the same for both, so please match the plug to your country.
• Model selection through Makeronline with one-click slicing requires a PC running Anycubic Slicer, according to the official footnote.
• This is a full-size enclosed machine weighing 25.7 kg, so it needs a sturdy bench and permanent floor or desk space rather than a shelf.
