If you love fast, reliable prints and a pinch of techy wizardry wrapped in a compact enclosed chassis — welcome. Today we deep-dive into Bambu Lab’s fresh P2S and compare it to its rock-solid predecessor, the P1S. This is a working-person’s review: specs, real-world differences, what actually matters for your prints, and which Filamigo filaments pair best with each machine (because a great printer + great filament = magic).

TL;DR — short and sweet
The P2S refines almost everything that made the P1S a bestseller: smarter extrusion & flow control, better UI, upgraded error detection, and generally better “out of the box” reliability for multi-material and single-filament workflows. If you’re choosing today, the P2S is the better long-term buy — especially if you use premium filaments (like Filamigo’s ZIRO PLA/PETG lines) or plan to run frequent multi-material prints. au.store.bambulab.com+1
What’s changed — headline upgrades in the P2S
Below are the main upgrades Bambu Lab introduced with the P2S versus the P1S, and why they matter:
1. Smarter extrusion & 70% more extrusion force
-
The P2S increases extrusion force and includes real-time flow compensation (pressure advance/flow-rate calibration built-in), which translates to cleaner retractions, better bridging, and more consistent extrusion on fast prints. This reduces visible seam artifacts and stringing vs older firmware/hardware combos.
2. Improved failure detection & diagnostics
-
P2S inherits advanced sensor and software checks (AI-assisted failure detection and better error reporting in the UI), meaning fewer mystery failed prints and easier troubleshooting. In plain English: your prints survive more “oops” moments.
3. Refined touchscreen & UX
-
Users report the touchscreen and overall UI in the P2S are more responsive and polished than the P1S—faster menus and clearer status feedback. Small things, big QoL (quality-of-life) gains.
4. Compatibility + AMS & accessories support
-
P2S keeps the P1S’ ecosystem strengths: enclosure, filter, and compatibility with AMS multi-spool systems — but with firmware refinements for better AMS-handling and filament switching. If you use or plan to use AMS, the P2S provides a more frictionless experience.
5. Price & positioning
-
Bambu positioned the P2S to be a “refresh” at roughly the P1S price point in many markets — effectively improving value. (Note: availability and regional launch timings varied; check local store pages.)

Real-world print performance: what you’ll feel
I know specs are fun, but what matters is your day-to-day printing:
Speed & quality
-
Both printers are CoreXY-driven and maintain the Bambu reputation for speed. However, the P2S’s improved extrusion force + flow compensation means it holds high-speed quality slightly better — fewer blobs, cleaner corners, and improved fine details at pace. Reviews from multiple outlets that tested real prints confirm this.
Multi-material & AMS printing
-
The P1S is already AMS-capable, but the P2S improves filament switching reliability and reduces failed color changes thanks to smarter pressure handling and flow tuning. If you frequently print multi-color or multi-material parts with AMS, the P2S is a clear step up.
High-temp materials (ABS, PC)
-
Both are enclosed and handle ABS and many engineering filaments well. The P2S does not add an active heated chamber like the larger H-series, so ultra-high-temp engineering polymers still belong with the X1/H-series for best results. That said, for most ABS and tough PETG uses, the P2S remains excellent.
Reliability & fewer mid-print surprises
-
Thanks to the improved sensors and diagnostics, the P2S tends to reduce mid-print failures (clogs, runout misreports, adhesion problems) compared to the P1S baseline. Users and early reviews flagged better “first-try” success rates.
Workflow, software & ecosystem
-
Bambu Studio & Handy App: Both printers integrate closely with Bambu’s ecosystem. Firmware and Studio improvements around print farm management and offline farm manager favor the P2S as a longer-term platform.
-
Cameras & timelapse: Camera functionality is comparable, but the P2S UI and streaming experience are a bit more polished.
-
Profiles & Filament: The P2S’s flow compensation means manufacturer profiles (for filaments) behave more predictably. That’s excellent if you want to use high-performance or specialty filaments without endless tuning.
Filament pairing — the Filamigo lineup + why they rock!
Great hardware deserves great filament. Filamigo’s lines are an excellent match for Bambu machines — consistent diameter, vacuum-sealed spools, and colour variety. Here are my top picks (click to buy):
-
Best all-round PLA (smooth prints, beautiful finishes): Filamigo ZIRO Silky PLA — ideal for display pieces and detailed models.
Buy: https://www.filamigo.com.au/collections/pla-pro-filament-1 (Silky PLA product pages). Filamigo -
Tough parts & general-purpose strength: Filamigo ZIRO PETG — great for functional parts, snap fits, and outdoor pieces. Works beautifully on both P1S and P2S; the P2S’s improved extrusion helps reduce PETG stringing.
Buy: https://www.filamigo.com.au/collections/petg-filament. Filamigo -
Show-off finish (gradient / special effects): ZIRO Gradient / Translucent PLA — for lamps, props, and eye-catching prints. The P2S’s flow consistency yields smoother color transitions.
Buy: https://www.filamigo.com.au/products/ziro-gradient-translucent-pla-season-series-filament-1-75mm. Filamigo -
Novelty & texture prints (stone/wood effects): Filamigo Stone PLA — for tactile props and props with a “stone” finish. The P2S’s better retraction control helps keep textured prints clean.

Practical pros & cons (quick list)
P2S — Pros
-
Better extrusion force & flow management → cleaner prints at speed.
-
Improved failure detection & diagnostics → fewer wasted spools.
-
Polished UI & smoother AMS handling.
-
Generally better long-term value at launch price point.
P2S — Cons
-
Not a dramatic mechanical overhaul — if you already own a P1S and it’s doing exactly what you need, upgrade benefits are incremental.
-
Availability can vary by region (watch for local stock & shipping updates).
P1S — Pros
-
Proven performer with a large user base and solid accessory ecosystem (AMS, filters, spare parts).
P1S — Cons
-
Lacks the P2S’s improved extrusion & diagnostics; may require more manual tuning to reach the same consistent print quality at speed.
Who should buy the P2S vs stick with a P1S
-
Buy the P2S if: you’re buying new today and want the better “set-it-and-forget-it” experience, plan to use AMS multi-material printing regularly, or rely on consistent prints with premium filaments (like Filamigo PLA/PETG). au.store.bambulab.com+1
-
Keep the P1S if: you already own one and you’re happy with the results, you don’t need the incremental features, and you’d rather spend on more filament and accessories.
Benchmarks & short tests (what reviewers found)
Multiple hands-on review outlets ran test prints and found:
-
Dimensional accuracy: Both machines score highly; the P2S often pulled ahead in high-speed tuning due to better extrusion control. Tom's Hardware+1
-
Print-first success rate: P2S had fewer failed prints from filament changes and early layers in early reviews. All3DP
Final verdict
Think of the P1S like your reliable favorite road bike — it gets you places fast and with joy. The P2S is the same bike with better brakes, a slightly stiffer frame, and a nicer saddle: the ride feels smoother, and you’ll go further before you need to service it. For most people buying today, the P2S is worth the upgrade for the improved reliability, better extrusion handling, and future-proofed firmware and UI.
If you want to maximize your prints, pair the P2S with Filamigo’s ZIRO filaments — Silky PLA for looks, ZIRO PETG for toughness, and Gradient PLA for show-stopping parts. Dive in at Filamigo:
