💰Anycubic Kobra S1 is $850 cheaper (244% less)
Cross-ecosystem comparison: These printers use different software ecosystems. Accessories, filament profiles, and community support are not interchangeable between brands. Consider the total ecosystem cost, not just the printer price.
Anycubic Kobra S1

First-generation product — no release history to base predictions on

Best for: Makers who want an enclosed 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.

Why buy each?

Anycubic Kobra S1

Enclosed CoreXY at 600 mm/s

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.

Anycubic ecosystem at prosumer price

Brings Anycubic's value-focused approach to the enclosed CoreXY segment — competing with Qidi Q2C and Bambu P2S at a lower price point.

250×250×250 mm build volume

A practical cubic build volume well-suited for functional mechanical parts, enclosures, and prototypes.

Prusa Research CORE One+

Prusa's answer to Bambu P-series

The CORE One+ matches Bambu CoreXY speed (600 mm/s) while keeping everything open source — firmware, hardware, slicing profiles.

Fully open source

Unlike Bambu's closed ecosystem, every component of the CORE One+ can be modified, repaired, or community-improved.

MMU3 multicolor compatible

Existing MMU3 units and the new MMU3 for CORE One bring 5-color multicolor printing to the CoreXY platform.
