Anycubic Kobra S1 Combo vs Bambu P2S Combo: Multi-Color Is Only Half the Comparison

Both systems target enclosed CoreXY buyers who want an integrated material feeder, but the hardware details differ enough that “multi-color” should not be the only criterion.

Build volume is effectively the same class

Six millimeters per axis is unlikely to matter for most parts, but exact fit is binary. Use the build-volume calculator with your largest real model rather than assuming either machine will fit because the nominal volumes look similar.

The feeder is part of the printer decision

ACE Pro and AMS 2 Pro affect drying, spool handling, color switching and material compatibility. A printer can support a filament that its automatic feeder should not handle. Separate “printer compatibility” from “multi-material-system compatibility.”

Temperature is not material proof

The Kobra S1's 320 °C hotend is higher than the P2S's listed 300 °C ceiling, but successful engineering-material printing also depends on nozzle material, enclosure behavior, build surface, drying and manufacturer profiles. Do not buy by nozzle temperature alone.

Before buying: the filament and feeder decision

For a multi-color print, validate each spool’s outer dimensions, material, temperature profile and feeder compatibility before choosing either bundle. The higher-level printer material list is not a guarantee that ACE Pro or AMS 2 Pro handles a particular spool or flexible polymer. Our multicolor spool compatibility checklist explains what to check, and the filament cost-per-print guide includes purge waste and failed prints. These buying guides disclose the approved Polymaker referral separately; this printer comparison does not treat either manufacturer as a Polymaker-approved dealer.
