Artillery M1 Pro S1 vs Creality K1
Technical comparison · Fused filament fabrication (FFF/FDM)
M1 Pro S1 and K1 cost almost the same, around €325, but start from different premises: one offers more print space and a hotter bed, the other ships with Klipper ready to use.

| Software notes | Artillery OS, a Klipper-based system. Compatible with standard slicers like Cura, PrusaSlicer and OrcaSlicer via G-code. Supports Wi-Fi transfer, SD card and touchscreen control. Compared to closed platforms, it allows advanced adjustment of printing parameters, but lacks a native cloud ecosystem and requires manual slicer configuration. | Pre-installed Klipper firmware with Creality OS interface. Wi-Fi connectivity and built-in 4.3" touch screen. |
The differences that matter
- Work area: 260×260 mm on M1 Pro S1 vs 220×220 mm on K1 → the M1 Pro S1 prints bigger parts in one piece.
- Native Klipper: pre-installed on K1, absent on M1 Pro S1 → only the K1 skips manual firmware setup.
- Multicolor printing: available on M1 Pro S1 with an accessory, absent on K1 → only the M1 Pro S1 allows automatic color changes.
- Bed temperature: 120°C on M1 Pro S1 vs 100°C on K1 → the M1 Pro S1 better handles technical filaments needing a hotter bed.
Which one to choose
Choose M1 Pro S1 if…
On the M1 Pro S1, parts up to 260×260 mm fit, against 220×220 mm on the K1, with a bed that heats to 120°C, useful with technical filaments, and multicolor printing available via a dedicated accessory. What's given up is pre-installed Klipper, which needs separate setup through Artillery OS.
Choose K1 if…
On the K1, Klipper comes pre-installed, ready to use without flashing or firmware conversion: macros, input shaping and community support are available right away. What's accepted is a smaller print area and a bed capped at 100°C, plus no multicolor printing.
