Why buy each?

Anycubic Kobra S1 Max

350×350×350 mm large-format build volume

One of the largest enclosed build volumes in the prosumer/professional tier — suited for large engineering parts, architectural models, and batch production.

65°C active chamber heating at scale

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.

Anycubic ecosystem continuity

The S1 Max extends the Kobra ecosystem into the large-format enclosed segment, enabling Anycubic users to scale up without switching brands.

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.
