The verdict
Buy the Prusa Core One.
8.2/10 vs Kobra S1 ACE 2 Pro Combo's 8/10, and it wins 2 of 5 categories. Outstanding print quality and the best support in the business. The price premium is real, though. If you don't care about the Prusa ecosystem specifically, there are better deals. If you do, it's worth every krona.

What owners say
16 colors on an enclosed CoreXY for under €500 was not on my 2026 bingo card. Anycubic is swinging hard at Bambu's multi-color dominance.

Pros & Cons
Kobra S1 ACE 2 Pro Combo
- +16-color capable (4 colors standard; 16 colors requires 4x ACE 2 Pro units purchased separately). Doubles the 8-color S1 Combo and quadruples the Bambu A1 Combo (4)
- +Fully enclosed CoreXY handles ABS, ASA, and engineering filaments without warping
- +44dB quiet mode is unusually low for a 600mm/s CoreXY — apartment-friendly
- −Brand new product — early adopter risk on firmware and ACE 2 Pro reliability
- −Anycubic slicer still trails Bambu Studio on automation and profile polish
Prusa Core One
- +Prusa reliability is not marketing. It's earned over years.
- +55C active chamber heating handles demanding materials
- +Fully open-source, no vendor lock-in anywhere
- −$1,199 assembled is hard to justify against the Bambu alternatives
- −Build volume is smaller than what you'd expect at this price
Buy these with it
A printer does nothing without these. Grab them in the same order.
- ELEGOO PLA filament, 1kgThe easy filament to start on. Prints at low temperatures and warps less.
- ELEGOO PETG filament, 1kgTougher and more heat tolerant than PLA, for parts that get handled or sit in the sun.
- SUNLU filament dryer S1 PlusWet filament causes stringing and rough surfaces. A dryer fixes that before you blame the printer.
