Anycubic Kobra S1 vs Bambu Lab A1
Technical comparison · Fused filament fabrication (FFF/FDM)
Choose Anycubic Kobra S1 if you need to print technical materials requiring an enclosed chamber (nozzle up to 320 °C, bed 120 °C) and higher speeds. Choose Bambu Lab A1 if you prefer a more compact and lightweight system (8.3 kg vs 18 kg), optimized for its proprietary software ecosystem at a lower price.

| 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 A1 works natively with Bambu Studio, Bambu Lab's proprietary slicer available for Windows and macOS, which handles slicing, automatic calibrations, and remote monitoring via the Bambu Handy app. Third-party slicers — including PrusaSlicer, SuperSlicer, and Ultimaker Cura — are supported via standard G-code export, but advanced features such as vibration compensation and active flow control are only available within the Bambu ecosystem. |
The differences that matter
- Kinematics and Structure: The Kobra S1 uses a CoreXY system with an enclosed chamber weighing 18 kg, while the A1 is an open Cartesian printer weighing only 8.3 kg.
- Temperatures and Speed: Kobra S1 reaches 320 °C at the nozzle, 120 °C on the bed, and a maximum speed of 600 mm/s. The A1 stops at 300 °C, 100 °C, and 500 mm/s.
- Multicolor Printing: Both require an accessory for multicolor, but Anycubic supports up to 8 colors, whereas Bambu Lab maxes out at 4.
- Firmware: The Kobra S1 runs native Klipper via Kobra OS, while the A1 uses proprietary firmware deeply integrated with Bambu Studio.
Which one to choose
Choose Kobra S1 if…
Choose Anycubic Kobra S1 if you work with high-temperature filaments and need a thermally stable environment thanks to the enclosed chamber, pushing up to 600 mm/s with CoreXY architecture and handling up to 8 colors.
Choose A1 if…
Choose Bambu Lab A1 if you are looking for a lighter, more affordable Cartesian printer suitable for standard materials (up to 300 °C), and want to fully utilize out-of-the-box integration with Bambu Studio for up to 4 colors.
