The Anycubic Kobra S1 Max (professional) and Creality K3 (prosumer) come from different brands and sit in different tiers, so this is less a head-to-head than a question of how much printer you need. Both are CoreXY printers with 4-slot multicolor and automatic calibration. The K3 costs $50 more and gets you support for PET and PCTG; the Kobra S1 Max answers with an enclosed chamber (with ABS, ASA, PA, PA-CF, PC and PET-CF on its materials list) and 144% more build volume.
First-generation product — recently released, still early days
Best for: Professional makers and small studios who need large-format enclosed printing for engineering filaments at a competitive price — and want Anycubic's ecosystem over Creality or Qidi alternatives.

Best for: Multicolor hobbyists and small creators who are tired of purge towers and filament waste, and who want tool-changer-style multicolor at well under half the price of Bambu's tool changers.

The Kobra S1 Max was released on Nov 25, 2025, 352 days ago. It is a first-generation product, so there is no earlier cycle to predict its successor from.
The K3 was released on Oct 13, 2026, 30 days ago. It is a first-generation product, so there is no earlier cycle to predict its successor from.
Both are early enough in their cycles that timing should not decide this one. The Kobra S1 Max launched 352 days ago and the K3 launched 30 days ago. Pick on features and price.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The Kobra S1 Max lists at $799 and the K3 at $849 — $50 apart, so the K3 costs 6% more.
Per litre of build volume, that works out to $19 for the Kobra S1 Max versus $48 for the K3 — the Kobra S1 Max is both cheaper and roomier, so it wins on value outright.
If you are buying before Dec 5, 2026, the active sale tips value toward the Kobra S1 Max.
Our pick for most buyers is the Kobra S1 Max, for an enclosed chamber (with ABS, ASA, PA, PA-CF, PC and PET-CF on its materials list) and 144% more build volume. Go for the K3 instead if you want PET and PCTG — listed for the K3 but not the Kobra S1 Max. The Kobra S1 Max is also in a sale window right now (Black Friday 2026, until Dec 5, 2026).
How we judge timing and deals: read our methodology →
One of the largest enclosed build volumes in the prosumer/professional tier — suited for large engineering parts, architectural models, and batch production.
Maintaining 65°C across a 350×350 mm chamber is a meaningful technical achievement — ensuring consistent results for ABS, ASA, and PA across the full build plate.
The S1 Max extends the Kobra ecosystem into the large-format enclosed segment, enabling Anycubic users to scale up without switching brands.
Four docked nozzles swap in about 5 seconds, so color changes no longer require purging a single nozzle. Creality quotes up to 85% less filament waste and up to 80% shorter multicolor print times.
Nozzles from 0.2 to 0.8 mm can be mixed in one print using extra nozzles sold separately. With a dedicated nozzle, TPU 95A prints without the feeding problems common to filament-switching systems.
The K3 brings near-tool-changer multicolor to a sub-$900 printer, well below Bambu's $2,399 H2C and $2,499 H3C.
