+Prusa's QC is genuinely better than anyone else's: every printer is test-printed before shipping
+PrusaSlicer is open source and powerful, no subscription, no cloud required
+Customer support answers in hours, not weeks
+Spare parts available for 5+ year old models; no planned obsolescence
−200mm/s max is a third of what CoreXY machines do at half the price
−$929 for an open-frame bed-slinger is a hard sell in 2025
−Bambu's A1 Combo does more for $530 less
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
