The Anycubic Kobra S1 and Creality K3 are both prosumer-tier printers, but the K3 costs 1.7× as much — so the question is what the extra money buys. Both are CoreXY printers with 4-slot multicolor and automatic calibration. The K3 costs $350 more and gets you support for PET, PCTG, PLA-CF and PETG-CF and 12% more build volume; the Kobra S1 answers with an enclosed chamber (with ABS, ASA and PA on its materials list) and a top speed of 600 mm/s (vs 500).
First-generation product — no release history to base predictions on
Best for: Makers who want an enclosed multicolor CoreXY at a prosumer price for PLA, PETG, ABS, and ASA — and prefer the Anycubic ecosystem. For reliable PA or PC printing, consider the Kobra S1 Max or Qidi Q2 which offer active chamber heating.

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 was released on Feb 11, 2025, 639 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.
On timing alone, the K3 is the safer buy right now — it launched only 30 days ago, while the Kobra S1 has no release history pointing to a successor yet.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The Kobra S1 lists at $499 and the K3 at $849 — $350 apart, so the K3 costs 70% more.
Per litre of build volume, that works out to $32 for the Kobra S1 versus $48 for the K3 — the Kobra S1 is the better value per litre as well.
If you are buying before Dec 5, 2026, the active sale tips value toward the Kobra S1.
Our pick for most buyers is the Kobra S1, for a lower price ($350 less) and an enclosed chamber (with ABS, ASA and PA on its materials list), plus a higher editor score (8.3 vs 8.0). Go for the K3 instead if you are buying now — it is the safer pick on timing (recently launched, vs no cycle history for the Kobra S1). The Kobra S1 is also in a sale window right now (Black Friday 2026, until Dec 5, 2026).
How we judge timing and deals: read our methodology →
The Kobra S1 combines an enclosed build chamber with 600 mm/s CoreXY motion — offering improved heat retention over open-frame printers for ABS and ASA.
Brings Anycubic's value-focused approach to the enclosed CoreXY segment — competing with the Qidi Q2 and Bambu P2S, with multicolor and filament drying included at $499.
A practical cubic build volume well-suited for functional mechanical parts, enclosures, and prototypes.
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.
