How It Scores
Pros
- +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
Cons
- −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
