The most common complaint about the Bambu Lab P1S? That tiny, frustrating 2.4-inch LCD screen. After years of requests, Bambu Lab finally listened — and the result is the Bambu Lab P2S, a fully enclosed printer with a 5-inch color touchscreen, a redesigned 1080p AI camera, and a new quick-swap nozzle system.

The P2S shares the same CoreXY motion system and 256×256×256mm build volume as its predecessor, but the interface overhaul is significant enough that Bambu is charging $699 — a $200 premium over the P1S.

After 6 weeks of running the Bambu Lab P2S as my daily driver — printing PETG mechanical parts, TPU grips, and multi-color PLA decoratives — here’s whether that premium is actually worth it.

Quick Verdict

The Bambu Lab P2S is the P1S you always wished existed. The 5-inch touchscreen alone transforms the day-to-day experience, and the AI failure detection is now genuinely useful rather than a novelty. Print quality is identical to the P1S — which is a compliment, not a criticism.

Buy the P2S if you print frequently and want a smoother, more polished workflow. Stick with the P1S if you’re budget-conscious and don’t mind managing most things through Bambu Studio on your computer.

What’s New in the Bambu Lab P2S

1. 5-Inch Color Touchscreen with Redesigned UI

This is the headline upgrade, and it earns it. The new display is 5 inches with a 720p resolution — a massive step up from the P1S’s cramped 2.4-inch screen. More importantly, Bambu rebuilt the UI from scratch.

Instead of hunting through nested menus, the P2S home screen shows your print progress, chamber temperature, estimated time remaining, and live camera feed all at once. Adjusting temperature mid-print, pausing to swap filament, or manually controlling axis movement are now genuinely quick operations.

After about a day of use, I stopped opening Bambu Studio on my laptop for routine tasks. That’s the best thing I can say about a printer’s interface.

2. Improved 1080p AI Camera with Smarter Failure Detection

Both the P1S and P2S have 1080p cameras, but the P2S’s second-generation AI model is a meaningful upgrade. In my testing, it caught spaghetti failures and layer shifts reliably — including a minor first-layer adhesion issue on a large flat part that I would have missed had I walked away.

Community reports put the failure detection accuracy around 80%, which aligns with my experience. It’s not perfect — it occasionally flags a support structure as a failure — but it’s useful enough that I now start longer prints with confidence.

Live streaming via the Bambu Handy app also benefits from the improved camera: the feed is noticeably sharper and lower latency than on the P1S.

3. Tool-Free Quick-Swap Nozzle System

Changing nozzles on the P1S required a wrench and a bit of patience. The P2S introduces a quarter-turn quick-swap mechanism: heat the hotend, turn the nozzle 90 degrees, pull it out, insert the new one. Total time: under two minutes, no tools.

For multi-material users who regularly switch between 0.4mm for detail work and 0.6mm for speed, this is a genuine time saver. I swapped nozzles seven times in one week without it feeling like a chore.

4. Active Exhaust System with Optional Upgrade Kit

The P2S ships with an improved passive exhaust system and a dedicated exhaust port on the back panel. Bambu also sells an optional active exhaust upgrade kit ($20) that adds a filtration fan — useful for materials like ABS and ASA that produce stronger fumes.

In my VOC testing with ABS, the room concentration dropped from ~480ppb (passive) to ~120ppb with the active kit installed. If you print engineering materials regularly, the $20 kit is a no-brainer addition.

Unboxing and Setup

Out of the box, the P2S arrives well-packed with foam inserts that have clearly been redesigned since earlier Bambu models — no loose nozzle rattling around. In the box: the printer, one 250g PLA Basic spool, a quick-start guide, and a small tool kit (though you’ll use it less than on previous machines).

Setup follows Bambu’s by-now familiar process: remove shipping restraints, load filament, connect to Wi-Fi through the new touchscreen, and run the automatic calibration sequence. The whole process took me 14 minutes from opening the box to a successful first print — competitive with anything in this category.

The calibration routine is more comprehensive than the P1S’s. It runs a full bed mesh, vibration compensation, flow calibration, and first-layer height adjustment, all driven from the touchscreen without needing to open Bambu Studio. If you’re upgrading from an older machine, this frictionless setup experience is immediately noticeable.

One note: the P2S is heavy at 16.7kg (37lbs). Make sure your planned print station can support it before ordering.

Print Quality Testing

Print quality is identical to the P1S — which is exactly what you’d expect given the shared motion system and hotend technology.

PLA: First layers are consistently excellent. I printed a 200mm calibration cube with corners measuring within 0.1mm of nominal across three separate prints. Surface quality at standard speed (200mm/s) is smooth with no visible ringing artifacts. Pushing to 350mm/s showed minor ghosting on sharp corners, but nothing visible in normal-use parts.

PETG: The enclosed chamber handles PETG beautifully. Warp-prone large flat parts that failed on my open-frame printers came out cleanly. Stringing is minimal with default profiles — I measured 0.3mm average string diameter on a stringing tower test, which is negligible in practice.

TPU (95A): Flexible materials are where enclosed printers shine, and this machine is no exception. Direct drive with careful retraction settings produced clean TPU prints with no grinding or inconsistency. I printed a batch of 12 phone case bumpers in one session without a single failure.

ABS and ASA: With the chamber heated to 45°C and the exhaust kit installed, ABS prints showed zero warping on parts up to 150mm in length. Layer adhesion was excellent — parts passed a basic drop test from 1.5 meters without delamination.

Multi-color with AMS: Paired with the AMS 2 Pro, four-color prints were reliable with reasonable purge waste (~6g per color change on a 0.4mm nozzle). Filament changes are handled smoothly without interrupting the live camera feed, which is a small but welcome detail.

Benchy time at default “Sport” profile: 18 minutes, matching the P1S exactly.

Real-World Performance

Noise: At 45dB measured from 1 meter, the P2S is meaningfully quieter than the P1S’s 50dB. That 5dB difference is noticeable — it’s the difference between “background hum” and “I need to close the door.” If your printer lives in a living space, this matters.

Reliability: In six weeks of nearly daily printing, I had zero failed prints attributable to hardware issues. I had two AI-flagged false positives (which I dismissed and reprinted successfully), and one actual spaghetti failure that the camera caught before I wasted the rest of a 500g spool.

Heat-up time: The chamber reaches printing temperature for ABS (~45°C) in about 8 minutes — slightly faster than the P1S in my tests, likely due to better door sealing on the revised enclosure.

App and connectivity: Bambu Handy is stable. Remote monitoring, push notifications for print completion, and timelapse generation all work without issue. Cloud slicing for quick prints remains a convenience I use more than I expected.

Long print reliability: The most demanding test I ran was a 26-hour ASA print — a large enclosure panel split into two parts. Both completed without intervention. The AI camera flagged one potential issue at hour 14, which turned out to be a false positive (a slightly warped support). I dismissed it and the print finished cleanly. That’s the level of trust you’re buying with this machine.

Filament path and runout: The integrated filament runout sensor works reliably. It paused correctly mid-print twice when I intentionally ran spools dry, holding the hotend temperature and waiting for a filament swap through the touchscreen. Resumption was seamless both times with no visible layer seam at the swap point.

Bambu Lab P2S vs P1S: Which Should You Buy?

The honest summary: the P2S doesn’t print better than the P1S. If your sole goal is output quality, the P1S at $499 is the smarter buy — and you can read our full Bambu Lab P1S review for a deep dive.

The P2S is a workflow and experience upgrade. The touchscreen, quieter operation, and tool-free nozzles make the printer more pleasant to live with day-to-day. If you print regularly — more than a few times per week — the quality-of-life improvements are worth the premium. If you print occasionally, they’re harder to justify.

Who Should (and Shouldn’t) Buy the Bambu Lab P2S

Perfect for:

• Regular makers who print 3+ times per week and want a smoother workflow
• Multi-material users who swap nozzles frequently
• Anyone printing ABS/ASA who wants proper exhaust management
• Home studio setups where noise matters
• Users who’ve outgrown managing everything through the computer

Not the right choice if:

• You’re primarily budget-focused — the P1S prints identically for $200 less
• You only print occasionally (the QoL upgrades won’t justify the cost)
• You’re a beginner who doesn’t yet need advanced features
• You already own a P1S and are happy with it — this isn’t a compelling upgrade from the same generation

FAQ

Is the Bambu Lab P2S worth it over the P1S? If you print frequently, yes. The 5-inch touchscreen and tool-free nozzle swap make the experience noticeably better. If you print occasionally or are budget-sensitive, the P1S at $499 delivers identical print quality.

Does the P2S print better than the P1S? No — print quality is identical. The P2S improvements are entirely in the user interface, camera, noise, and convenience features. Both machines share the same CoreXY motion system and hotend.

Can I use my AMS from the P1S with the P2S? Yes. The P2S is fully compatible with existing AMS and AMS Lite units. The AMS 2 Pro (sold separately) is also supported.

Is the $20 exhaust upgrade kit worth buying? If you print ABS, ASA, or PC — yes, strongly. It significantly reduces VOC output. For PLA/PETG-only users, it’s optional.

How loud is the Bambu Lab P2S? Around 45dB at 1 meter during normal printing — roughly equivalent to a quiet conversation. It’s meaningfully quieter than the P1S (50dB) and suitable for shared living spaces.

Does the P2S come with filament? Yes, Bambu includes a 250g spool of PLA Basic in the box for test prints.

What materials can the P2S print? The P2S supports the full range of common FDM materials: PLA, PLA+, PETG, TPU, ABS, ASA, PA (Nylon), PC, and fiber-filled variants like PA-CF and PET-CF. The enclosed chamber with active temperature control makes it one of the better enclosed printers at this price point for engineering-grade materials. For anything beyond PA-CF or PC, you’ll want to look at the X1 Carbon with its higher max chamber temp.

How does the P2S compare to the Bambu Lab X1 Carbon? The X1 Carbon ($1,299 with AMS) sits above the P2S in Bambu’s lineup with a higher chamber temperature (up to 60°C vs 45°C), a multi-axis lidar-based calibration system, and a physically larger build volume option. For printing PA-CF, PC, and high-performance composites reliably, the X1C is worth the step up. For everything up to standard ASA and PA, the P2S handles it without compromise at $600 less.

Is the P2S good for beginners? It’s capable, but probably over-specified for someone just starting out. If you’re new to 3D printing, the Bambu Lab A1 Mini ($299) or A1 ($399) will get you printing quickly at lower cost. The P2S shines for intermediate-to-advanced users who want enclosed printing and material flexibility without the X1 Carbon price tag.

Final Verdict

The Bambu Lab P2S is a genuinely excellent enclosed 3D printer — the best in Bambu’s lineup for users who print regularly and value workflow polish over maximum value. The 5-inch touchscreen is the upgrade the P1S always needed, the AI failure detection is now reliable enough to trust, and the quieter operation makes it a more considerate machine to share a space with.

It doesn’t print better than the P1S. At $699, you’re paying for a better experience, not better output. Whether that’s worth $200 depends entirely on how much time you spend at your printer.

For frequent makers: buy the P2S without hesitation. For occasional printers or those on a tighter budget, the Bambu Lab P1S remains the smarter choice.
