Bambu Lab P1S — Detailed Review

An enclosed CoreXY powerhouse combining blazing print speeds, reliable automation, and optional multi-color via AMS.

256³ mm Build Enclosed CoreXY 500 mm/s Max Speed 20,000 mm/s² Acceleration AMS Multi-Color Ready

Overview

The Bambu Lab P1S elevates the P1P by adding a robust enclosure, welded steel chassis, and noise suppression—all while retaining lightning-fast CoreXY performance. It prints up to 500 mm/s with 20,000 mm/s² acceleration, auto-levels the bed, and includes vibration compensation and pressure advance for flawless print fidelity. AMS compatibility provides seamless multicolor capability up to 16 colors with chained units.

Strengths & Trade-offs

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

Considerations

Cost & footprint: Heavier and more expensive than non-enclosed P1P.
Interface limitations: Uses a D-pad controlled mono screen rather than touchscreen.
Cloud dependency: Requires Bambu's ecosystem for full feature access, which some users criticize.

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.

All3DP similarly praises its combination of affordability, performance, and ease of use.

The NextLayer highlights how it expands material compatibility compared to the P1P, making it a “really great printer.”

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.
