P2S Combo Overview: What’s New Compared to P1S & Why It Matters

P2S Combo Overview: What’s New Compared to P1S & Why It Matters

Bambu Lab’s P1S has long been a reliable go-to for makers needing a fully enclosed, CoreXY printer with multi-material support via AMS. But with the release of the P2S Combo, Bambu Lab is pushing that platform further — integrating enhancements from higher-end models (like H-series) to make it more future-proof and capable.

In this post, we’ll compare what’s new in the P2S versus the P1S, why those changes matter in day-to-day printing, and who should consider upgrading.

🔍 What’s Changed: Key Upgrades in the P2S Over P1S

Here are the major improvements and new features in P2S (as reported by reviews, announcements, and leaks) compared to P1S:

Feature P1S P2S (New / Upgraded)
Build Volume 256 × 256 × 256 mm Same: 256 × 256 × 256 mm 
Top Speed Up to 500 mm/s Increased—reportedly up to 600 mm/s 
Bed Temperature Standard heated bed (up to ~100-110 °C) Heated bed increased to 110 °C 
User Interface / Display Monochrome or simpler screen New 5-inch color touchscreen with updated UI, borrowed from H-series models 
Adaptive Airflow & Chamber Control Enclosed chamber, passive airflow New Adaptive Airflow System that draws external cool air when needed while maintaining chamber environment 
Extruder & Motion Hardware Standard P-series hardware Upgraded extruder hardware, better sensors and reliability (from reports) 
Multi-Material Support Requires AMS add-on P2S Combo ships with AMS 2 Pro built-in (multi-filament capability) 
Material Compatibility PLA, PETG, ABS, some PC Maintains wide compatibility up to PC, but lacks active chamber (so may still be limited vs H-series) 
Reliability & Workflow Enhancements Proven but dated interface More refined, reliable, smarter error detection, and firmware enhancements 

 

🛠 Why These Changes Matter — For You

Upgrades sound nice on paper, but what do they actually mean in real printing scenarios?

  • Faster Printing with Confidence
    Pushing from 500 mm/s to 600 mm/s means you can complete models quicker. The updated extruder, better sensors, and cooling system make that speed usable rather than just theoretical.

  • Better Adhesion & Material Options
    The hotter bed (110 °C) opens up better adhesion for filaments like ABS or PC, which often struggle on cooler surfaces. That helps avoid warping and improves layer bonding.

  • Smarter Airflow = Cleaner Prints
    The P2S’s Adaptive Airflow automatically regulates chamber environment, letting you close the door even during printing of standard filaments without overheating or print defects.

  • More Reliable Multi-Material from the Start
    Having AMS 2 Pro integrated means P2S is multi-material ready out of the box. No separate add-ons required, which lowers barrier to start printing color or support-material combinations.

  • Fresher UI & Workflow
    The 5-inch color touchscreen and updated UI speed up setup, make status easier to check at a glance, and reduce friction in everyday use. Less time messing with menus, more time printing.

  • Better Hardware Durability & Maintenance
    Upgraded sensors, more robust components, and hardware refinements reduce calibration needs, downtime, and mechanical failures over time.

💡 Considerations & Trade-Offs

No upgrade is perfect. Here are some things to be aware of:

  • No active heated chamber
    Unlike H-series, P2S doesn’t (for now) include a full chamber heater, so printing very heat-sensitive filaments still might be limited.

  • Filament waste from color swaps
    As with most single-nozzle multi-material printers, you’ll still have purge waste when switching filaments.

  • Closed ecosystem
    Bambu Lab tends toward integrated software and firmware. If you like modding or custom firmware, you may hit limitations.

  • Price premium
    With more features, the P2S is likely more expensive than P1S—and whether the upgrade is worth it depends on how much you use the advanced features.

✅ Should You Upgrade or Get a P2S Instead of P1S?

Choose P2S if:

  • You want a modernized, faster printer with all the newer features.

  • You plan to use multi-material printing frequently.

  • You value smoother workflow, smarter sensors, and more reliable hardware.

  • You want capability for tougher materials (ABS, PC) without jumping to the H-series.

Stick with P1S if:

  • You already own one and it still meets your needs.

  • You mostly print PLA, PETG without needing the extra speed or features.

  • Price sensitivity is important, and you don’t need all the new hardware.

The P2S Combo is not just a refresh—it brings several H-series features down into a more accessible format. For makers and professionals, it offers a compelling middle ground: performance upgrades, smoother workflow, and future-proofing—without completely stepping into premium printer territory.
