Anycubic Kobra S1 Max 3D Printer (Printer Only)
Large enclosed prints in ABS, ASA, PC and CF blends
An enclosed CoreXY printer with a 350 mm cube build volume, a 350C hardened steel nozzle, a 120C PEI bed and active chamber heating to 65C, plus LeviQ 3.0 levelling, a 720p camera and Wi-Fi and Ethernet. This listing is the printer only, without the ACE 2 Pro colour unit.

Fit and limits
Strengths
- 65C heated chamber and 350C nozzle for engineering filaments
- Spare 0.6 mm hardened nozzle and carbon pack in the box
- Wi-Fi, Ethernet and a LAN mode alongside the cloud app
Caveats
- No ACE 2 Pro in this box; colour and drying need it added
- 25.7 kg machine that needs a 503 x 483 mm footprint
- Store page drops TPU from one filament list but keeps it elsewhere
Printer only: what that leaves out
The listing title calls this the Kobra S1 Max FDM 3D Printer Only, and its box field lists just the printer. Anycubic sells the same machine as a Combo with its ACE 2 Pro filament unit, and its store page lists multicolour printing as sold separately and active filament drying as not supported for the standalone printer, while its comparison shows drying up to 65C on the Combo.
The user manual's packing list for the Kobra S1 Max includes the power cord, filament samples, a spool holder assembly, hex keys, grease, a nozzle cleaner and cleaning module, a nozzle parking pad, a spare 0.6 millimetre hardened steel nozzle and an activated carbon pack. The FAQ confirms a 0.4 millimetre hardened steel nozzle comes pre-installed.
The FAQ says the Kobra S1 Max works with the ACE 2 Pro and not with the first-generation ACE Pro, and that up to four ACE 2 Pro units with additional hubs allow 16 colours. If you plan to add colour later, plan on an ACE 2 Pro rather than an older ACE Pro.
Size and weight
Build volume is 350 by 350 by 350 millimetres. The manual and FAQ give machine dimensions of 502.7 by 483 by 584 millimetres and a net weight of 25.7 kilograms. The packed printer weighs 31 kilograms in a 583 by 560 by 693 millimetre box, according to the FAQ.
The listing gives 69.3 pounds and 20.08 by 22.83 by 18.9 inches, and does not say whether those figures describe the packed printer or the machine; its dimensions do not line up with Anycubic's 502.7 by 483 by 584 millimetre machine size in the same order.
Rated power in the manual is 1,000 watts on 110 volts and 2,200 watts on 220 volts. The manual asks that the printer be stored somewhere cool and dry when idle for a long period, and it specifies a 250 volt, 10 amp fuse if the fuse is ever replaced.
Heat: nozzle, bed and a 65C chamber
Anycubic lists a 350 degree Celsius hotend, a 120 degree PEI spring steel bed and active chamber heating to 65 degrees. The FAQ says the 65 degree chamber helps prevent warping on materials such as ABS carbon fibre.
The manual's filament list is PLA, PETG, TPU, PET, PLA-CF, PETG-CF, PVA, ABS, ASA, PC, PA, PA6-CF, PC-CF, PC-GF and PET-CF. The FAQ splits these into consumer-grade and engineering-grade and names TPU as 95A. The store page's specification table leaves TPU out of its list while its feature section includes TPU 95A, so check with Anycubic for your specific TPU.
Extrusion uses a short-distance extruder with hardened steel gears, and nozzles are swappable through a quick-release hotend with 0.25, 0.6 and 0.8 millimetre options. The FAQ says 0.25 millimetre nozzles are brass and the others hardened steel.
Speed, levelling and sensing
Anycubic gives a recommended printing speed of 300 mm/s with a 600 mm/s maximum, and recommended acceleration of 10,000 mm/s squared with a 20,000 maximum. The listing matches, calling 300 mm/s the default. Layer thickness runs from 0.08 to 0.28 millimetres.
Levelling is LeviQ 3.0 automatic levelling, with area levelling and object skip supported. Pressure advance and flow calibration, power loss resume, filament run-out detection with auto resume, entanglement detection and AI spaghetti detection are all listed as supported.
A 720p camera provides monitoring and time-lapses through the Anycubic app. Anycubic lists noise at 48 dB or less in standard mode and 45 dB or less in quiet mode, and the listing gives the same numbers.
Connectivity, software and setup
The manual lists 2.4 and 5 GHz Wi-Fi, and the store page adds an Ethernet port and describes switching between Anycubic's cloud platform and LAN mode. Slicing is Anycubic Slicer Next or OrcaSlicer, with STL, OBJ and 3MF input and G-code output, and printing can start from the printer, the slicer, the app or a USB drive.
Anycubic says the printer arrives 95 percent pre-assembled. The manual covers unlocking the printhead and heated bed from their shipping restraints and fitting the spool holder, activated carbon pack and lead screw dust cover before first power-on; follow it step by step.
Firmware is Kobra OS and the touchscreen is 4.3 inches. The FAQ lists ten interface languages. Anycubic's discharge chute sits on the left side of the printer, so leave access to it.
Maintenance, safety and warranty
The manual asks for regular lubrication of the lead screw, linear rod, guide rail, idler pulley and extruder wheel, with oil on the rails, rod and pulley and grease on the lead screw and extruder wheel. It also asks for checks on plastic and rubber parts, cutter blades, silicone wipes and PTFE tubes, and cleaning of the fan, camera lens and filament sensor.
Its precautions warn about moving parts and hot surfaces, recommend heat-resistant gloves for maintenance, and say to keep the printer and small parts away from children. Follow the manual for those procedures rather than a summary.
Anycubic's store page advertises a one-year warranty for 3D printers alongside its return terms. We did not read a separate warranty policy document, so confirm what that year covers and whether it applies to an Amazon purchase.
