Anycubic Kobra S1 Max Combo vs Snapmaker U1
Technical comparison · Fused filament fabrication (FFF/FDM)
Choosing between these two FDM printers mainly comes down to enclosed build volume versus multicolor handling: the Kobra S1 Max Combo offers a 350 mm-per-side enclosed chamber, the U1 four built-in toolheads that switch color without an external accessory.

| Software notes | The firmware runs on a proprietary Kobra OS layer built on top of Klipper; the official slicer is Anycubic Slicer Next, derived from OrcaSlicer, available for Windows and macOS. Third-party OrcaSlicer is also supported. Remote monitoring and control are available via the Anycubic app (iOS/Android) over LAN, with no mandatory cloud connection required for core printing functions. | The primary software is Snapmaker Orca, an optimized version of the popular OrcaSlicer, which provides native management of the four toolheads and factory-calibrated material profiles. The printer can also be seamlessly managed via the Snapmaker mobile app for remote monitoring, taking advantage of the built-in 1080p camera. The internal firmware is built on Klipper, Moonraker, and Fluidd, which Snapmaker has made open-source, allowing experienced users to customize the machine and integrate it into complex workflows. |
The differences that matter
- Build volume: 350×350×350 mm on the Kobra S1 Max Combo against 270×270×270 mm on the U1.
- Enclosed chamber: only on the Kobra S1 Max Combo.
- Built-in multi-extruder: only on the U1, handling 4 colors with no external accessory.
- Firmware: native Klipper on the U1, a proprietary Kobra OS layer on the Kobra S1 Max Combo.
Which one to choose
Choose Kobra S1 Max Combo if…
Anyone printing large parts or materials needing an enclosed chamber — ABS, ASA — uses the Kobra S1 Max Combo's 350×350×350 mm volume, with a declared nozzle temperature up to 350 °C and a bed up to 120 °C. The trade-off is managing multicolor through an external accessory, limited to 4 colors.
Choose U1 if…
Anyone who wants multicolor without extra accessories uses the U1's four built-in toolheads, on native, open Klipper firmware (Moonraker, Fluidd). The trade-off is a smaller build volume (270×270×270 mm) and no enclosed chamber.
