Why consider it?

A 350 × 350 × 350 mm volume in an enclosed CoreXY chassis, an active 65°C heated chamber, a nozzle advertised up to 350°C, and dual external cooling fans per Anycubic.

What to verify

Multicolor isn't included as shipped: one or more ACE 2 Pro modules remain separate accessories. Check the exact bundle contents (included nozzles, plate) on the retailer's listing.

The base machine is single-color; one or more ACE 2 Pro modules are sold separately to add multicolor, up to 16 colors advertised with several units.
Materials
PLA, PETG, ASA, and specialty filaments (high-speed PLA, silk PLA, metal PLA) per Anycubic, thanks to a hardened nozzle up to 350°C.

Allow room for supports and the chosen orientation. Confirm the exact nozzle, feeder, included accessories and installation clearance against the manual and seller’s listing.

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.

Frequently asked questions

Is multicolor included on the Kobra S1 Max?

No, the base machine stays single-color per Anycubic. One or more ACE 2 Pro modules, sold separately, add multicolor with up to 16 colors advertised when combining several units.

What's the difference from the standard Kobra S1?

The Kobra S1 Max offers a 350 × 350 × 350 mm volume versus a more compact format on the Kobra S1, while keeping the same enclosed chamber heated to 65°C per Anycubic.

Is the heated chamber enough for ASA?

Anycubic advertises an active 65°C chamber combined with a nozzle up to 350°C, conditions compatible with ASA per the manufacturer, with a profile to adjust depending on the filament used.
