How much space does it need?
The Anycubic Kobra S1 Max measures 502.7 × 483 × 584 mm (19.8 × 19 × 23 in) for a 350 × 350 × 350 mm (13.8 × 13.8 × 13.8 in) build volume: the dashed box is the printer, the solid cube the largest theoretical part, about 30% of the machine’s volume. Add room for the spool or multicolor unit, cables and ventilation.

Which projects is it for?
The Kobra S1 Max targets enclosed large-format printing with a nominal build volume of 350 × 350 × 350 mm per Anycubic, a plate suited to bulky parts, batches, or several objects spread out without moving up a machine tier.
An enclosed CoreXY architecture paired with dual external cooling fans aims to sustain print speed even on a plate this size, per Anycubic, rather than slowing down noticeably compared with the smaller Kobra S1.
Materials and setup
A hardened nozzle advertised up to 350°C and a chamber actively heated to 65°C per Anycubic cover PLA, PETG, ASA, and specialty filaments like high-speed PLA, silk PLA, or metal PLA.
Multicolor isn't built into the base machine: Anycubic offers one or more ACE 2 Pro modules as separate accessories, with up to 16 colors advertised when combining several units.
What the bundle includes or not
The base machine ships with a pre-installed 0.4 mm hardened steel nozzle based on offers seen from Anycubic, with an optional 0.6 mm hardened steel nozzle and support for 0.25 mm brass or 0.8 mm hardened steel nozzles; the exact contents (extra nozzles, plate, accessories) vary between the standalone machine and "Combo" packs with an ACE module.
The dual external cooling fans and enclosed chassis aim for thermal stability suited to regular use on a 350 × 350 × 350 mm plate, an important detail for anyone printing large batches back to back.
Alternatives to compare
For a more compact format in the same lineup, the Kobra S1 stays a more accessible base with the same heated chamber. For an open frame and a tighter budget, the Kobra 3 covers a different use case.
The multicolor buying guide helps weigh whether one or more ACE 2 Pro modules are worth the extra investment on this machine.
