The Anycubic Kobra X (entry) 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 open-frame printers with 4-slot multicolor and automatic calibration. The K3 costs $450 more and gets you support for PET, PCTG, PLA-CF and PETG-CF; the Kobra X answers with a top speed of 600 mm/s (vs 500) and extra engineering materials (ABS).
First-generation product — recently released, still early days
Best for: Budget-conscious makers who want multicolor printing at the lowest possible entry price and don't need a large build volume or premium features.

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 X was released on Mar 1, 2026, 256 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 X launched 256 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 X lists at $399 and the K3 at $849 — $450 apart, so the K3 costs 113% more.
Per litre of build volume, that works out to $23 for the Kobra X versus $48 for the K3 — the Kobra X is the better value per litre as well.
Our pick for most buyers is the Kobra X, for a lower price ($450 less) and a top speed of 600 mm/s (vs 500). Go for the K3 instead if you want PET, PCTG, PLA-CF and PETG-CF — listed for the K3 but not the Kobra X.

Listed at $399 and frequently on sale for $279–299 with ACE Gen 2 included, the Kobra X is one of the most affordable ways to get into multicolor FDM printing.
The same cube-format build volume as the pricier Kobra 4 — practical for most everyday prints.
The second-generation ACE Gen 2 offers improved filament switching reliability over the original ACE Pro, with support for up to 4 colors per print.
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.
