Pros & Cons
Anycubic 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
+Upgraded hotend is rated for the full Anycubic filament range
+Early bird €459 undercuts the Bambu P2S (€549) and matches pricing of the older 8-color S1 Combo
−Brand new product — early adopter risk on firmware and ACE 2 Pro reliability
−Anycubic slicer still trails Bambu Studio on automation and profile polish
−ACE 2 Pro adds significant desk footprint
−Early bird pricing ends May 31 — regular price expected to climb
QIDI X-CF Pro
+One of the few sub-$600 printers with a genuine 60°C heated enclosure for PA-CF and PPS-CF
+Hardened steel nozzle ships standard — no upgrade needed for carbon fiber out of the box
+HEPA + active carbon filtration — safe for indoor use with engineering filaments
+Linear rails on all axes mean less positional drift on long industrial prints
+Proven track record in light manufacturing since 2021
−60-100mm/s print speed is 6x slower than modern CoreXY machines — long print times
−2021 vintage hardware; newer QIDI models (X-Plus 4, Tech Max) offer more for similar money
−Dual extruder adds mechanical complexity without multi-color usefulness for most users
−21.5kg — not portable, bench-only
−Slicer integration (Simplify3D profiles) trails modern Bambu/Creality ecosystems
