✅ Pros: Professional enclosed printing at a mid-range price.
❌ Cons: Basic screen and slower camera than X1-C.
✅ Pros: Fastest open-frame printer; incredible CoreXY value.
❌ Cons: No enclosure; basic LCD screen.
The P1S is the clear winner for most users because the fully enclosed design makes it much more versatile for advanced materials. The P1P is the winner for those who print exclusively in PLA and want to save some cash. **The trade-off:** You are paying extra for fans and panels on the P1S. We were disappointed that both still use the same low-quality monochrome screen. Spend the extra for the P1S to future-proof your hobby.
