Why buy each?

Anycubic Kobra 3

34% more build volume over original

The V2 expands to 255×255×260 mm — 34% more printable volume than the original Kobra 3 — for larger parts and more batch production.

AI monitoring camera included

The V2 includes a 720p camera for real-time print monitoring and AI spaghetti detection, adding reliability features previously absent from the Kobra 3 line.

4-color ACE Pro at budget pricing

The Kobra 3 V2 Combo with ACE Pro is one of the most affordable 4-color setups available — often underpricing Bambu's A1 Combo.

Prusa Research MK4S
