✅ Pros: Incredible reliability and industry-best support.
❌ Cons: Open frame design (enclosure is extra).
✅ Pros: Fastest open-frame printer; incredible CoreXY value.
❌ Cons: No enclosure; basic LCD screen.
The Prusa MK4S is the winner for reliability and long-term serviceability; it's a machine you can fix yourself. The P1P is much faster for simple prints and has a better ecosystem for beginners. **The truth:** Prusa is an investment in stability, while Bambu is an investment in speed. We were disappointed that the MK4S is still open-frame at this price point. Buy the Prusa for a business, or the P1P for the speed advantage.
