Anycubic Kobra S1 vs Bambu Lab P1S
Technical comparison · Fused filament fabrication (FFF/FDM)
Two enclosed CoreXY printers with nearly identical volume, both multicolor with an accessory: the choice is between the Kobra S1's Klipper-based firmware and the P1S's lower price, which reaches more colors.

| Software notes | The Kobra OS firmware is based on Klipper and controlled via a proprietary touch interface. The official slicer is Anycubic Slicer Next (derived from OrcaSlicer, available for Windows and macOS), but it also supports third-party OrcaSlicer. Remote control is possible via the Anycubic app (iOS/Android) over a local network, with no mandatory cloud connection for daily operations. | The P1S is managed through Bambu Studio, Bambu Lab's proprietary slicer available for Windows, macOS, and Linux, or via OrcaSlicer, the widely adopted open-source fork that provides finer parameter control. The Bambu Handy mobile app enables remote monitoring and print launching. The printer supports local LAN connections without a mandatory cloud account, though some advanced features — such as remote timelapses and OTA firmware updates — require a Bambu account. |
The differences that matter
- Native Klipper → not native: the Kobra S1 runs a Klipper-based firmware, the P1S runs Bambu's own, driven from Bambu Studio or OrcaSlicer.
- Up to 8 colors → up to 16, both with an accessory: how many different materials you load in one job.
- €549 → about €399–499: the P1S costs roughly a hundred euros less.
- Bed up to 120 °C and nozzle up to 320 °C → 100 °C and 300 °C: stated limits, the extra margin is on the Kobra S1.
Which one to choose
Choose Kobra S1 if…
You want Kobra OS built on Klipper, with OrcaSlicer or Anycubic's slicer and local-network control from the app, no mandatory cloud, for €549. The trade-off: up to 8 colors with the accessory against 16, about €100 more and a 250 × 250 mm bed, six millimeters less on a side.
Choose P1S if…
You print in more colors, up to 16 with the accessory, from Bambu Studio or from OrcaSlicer, on the local network with no account, for about €399–499. The trade-off: remote timelapses and OTA updates need a Bambu account, and Klipper is not native.
