Strengths & Trade-offs

Strengths	Why It Matters
Enclosed, stable design	Ensures consistent results with ABS, ASA, Nylon and other high-temperature materials. :contentReference[oaicite:9]{index=9}
Unmatched speed & precision	500 mm/s and 20,000 mm/s² with input shaping gives fast yet accurate production. :contentReference[oaicite:10]{index=10}
Seamless automation	Auto-leveling, vibration compensation and pressure advance simplify workflow and produce excellent print quality. :contentReference[oaicite:11]{index=11}
Multi-color with AMS	Optionally supports up to 16-color printing via chained AMS units. :contentReference[oaicite:12]{index=12}

Considerations

Cost & footprint: Heavier and more expensive than non-enclosed P1P. :contentReference[oaicite:13]{index=13}
Interface limitations: Uses a D-pad controlled mono screen rather than touchscreen. :contentReference[oaicite:14]{index=14}
Cloud dependency: Requires Bambu's ecosystem for full feature access, which some users criticize. :contentReference[oaicite:15]{index=15}

Expert Impressions

Tom’s Hardware calls the P1S “our favorite speedster and one of the best 3D printers we’ve seen,” citing its fast speeds and excellent auto-leveling and motion control. :contentReference[oaicite:16]{index=16}

All3DP similarly praises its combination of affordability, performance, and ease of use. :contentReference[oaicite:17]{index=17}

The NextLayer highlights how it expands material compatibility compared to the P1P, making it a “really great printer.” :contentReference[oaicite:18]{index=18}

Verdict

✅

Recommended if you want an enclosed CoreXY that blends speed, reliability, and automation, plus future-ready multicolor potential with AMS.

Consider alternatives if you prefer open-frame simplicity, touchscreen control, or want to avoid vendor cloud ecosystems.
