Anycubic Kobra S1 vs Artillery Sidewinder X4 Plus
Technical comparison · Fused filament fabrication (FFF/FDM)
Two filament printers with different price and build volume: the Kobra S1 is enclosed and runs hotter, the Sidewinder X4 Plus gives more room and costs about 140 euro less. It comes down to whether you print heat-hungry materials or large parts.

| 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 printer runs Marlin firmware with an open G-code protocol, compatible with any slicer like Cura, PrusaSlicer, or Simplify3D. Artillery Slicer is a customized version of Cura with optimized profiles. WiFi connectivity allows file transfer via a dedicated app but doesn't support a full web interface. Input shaping and pressure advance are preconfigured and factory-tuned, reducing initial calibration. |
The differences that matter
- Build height 400 mm against 250 mm → a 30 cm tall part prints whole on the Sidewinder; on the Kobra it has to be split in two and glued.
- Bed at 120 °C and nozzle at 320 °C against 100 and 300 °C → the Kobra leaves more margin with materials that need heat.
- Price 549 € against about 405 € → the Sidewinder costs about 140 euro less.
Which one to choose
Choose Kobra S1 if…
you print materials that need a 120 °C bed and a nozzle up to 320 °C, in an enclosed machine (manufacturer-declared values). You accept a 250 × 250 × 250 mm volume and about 140 euro more.
Choose Sidewinder X4 Plus if…
you print wide or tall parts, up to 300 × 300 mm on the bed and 400 mm high, and want to spend less. You accept a bed up to 100 °C and a nozzle up to 300 °C, so less headroom with demanding materials.
