The Anycubic Kobra S1 Max scales the enclosed Kobra platform to a 350 x 350 x 350 mm build volume. It combines a 65 C active chamber, a 350 C hotend and optional ACE 2 Pro material units, with a launch price advertised from $699 for the standalone printer.
That combination is aimed at large props and functional parts rather than merely stretching the bed of an entry-level machine. The heated enclosure and hardened nozzle also make engineering filaments a more credible use case.
A genuinely large enclosed build area
The 42.9-litre build space is substantially larger than the original Kobra S1. Anycubic uses CoreXY motion so the bed only moves vertically, which is preferable to throwing a heavy 350 mm plate back and forth at high speed. Automatic levelling and vibration compensation are intended to simplify setup.
Anycubic quotes a 600 mm/s maximum speed and recommends lower real printing speeds. Those headline figures are useful for travel and suitable geometry, but final throughput depends on volumetric flow, layer height and the size of the model.
Heated chamber and material capability
The hardened 350 C nozzle, 120 C bed and active 65 C chamber are the standout specifications. They should help reduce warping on ABS, ASA, polycarbonate, nylon and selected fiber-filled materials. A large hot chamber also consumes more power and needs clearance around its ventilation, so it deserves a permanent location rather than a small shelf.
The printer includes two cameras for monitoring and AI-assisted detection, plus Wi-Fi 6 and Ethernet. Network features are convenient for large jobs, although the manual also lists OrcaSlicer alongside Anycubic Slicer Next, giving users a more open slicing option.

ACE 2 Pro and pricing
The standalone machine prints one material at a time. Adding an ACE 2 Pro provides four-spool selection and active filament drying; more units are required for 8 or 16 colors. This adds cost, space and purge waste, so a single four-spool system will be the practical choice for many users.
Anycubic advertised the standalone printer from $699 and a one-ACE Combo from about $899, against higher displayed list prices. These launch offers change by region. Independent long-term coverage remains thinner than for established competitors, so early buyers should also examine warranty support, firmware history and owner feedback rather than relying on specifications alone.
A strong specification, with early-adopter caution
On paper, the Kobra S1 Max offers an unusual amount of heated build volume for the price. It is most compelling for users who actually need 350 mm parts or stable engineering-material printing. Smaller PLA projects do not exploit its main advantages.
The hardware proposition is clear, but the evidence base is still developing. Buyers who cannot tolerate downtime may prefer to wait for more long-duration independent tests and firmware revisions. Those willing to accept that early phase get one of the most ambitious large enclosed CoreXY packages in its price class.
