Bambu Lab P2S vs A1: Full Comparison & In-Depth Review – Is the Upgrade Worth It?

Last year, I shared a VLOG about transforming a forgotten corner of my home with the Bambulab A1, and it unexpectedly resonated with tons of fellow 3D printing enthusiasts. Fast forward a year, I’ve printed countless tools, toys, and custom gadgets with the A1 – every time I post the finished products on social media, the "that’s so cool!" comments pour in. Then the Bambulab P2S dropped, and after a month of hands-on use, I can confidently say: this upgrade isn’t just incremental – it’s a game-changer for anyone craving "set-it-and-forget-it" convenience and pro-level performance.

For me, 3D printing’s biggest appeal isn’t about saving money (let’s be real, you can overthink filament costs, electricity, and depreciation). It’s the thrill of creating one-of-a-kind items that you can’t find in stores – all for pennies in filament.
Over the past year with the A1, I’ve printed everything from a Zelda Master Sword replica and a dinosaur pen holder for my desk, to a Toothless phone stand, cyberpunk Goku figurines, Fat Buu, Kirby, and even a Sun Wukong statue and a "Megalodon" quad bike from my childhood. I mixed custom color combinations that you won’t find anywhere else, and the sense of accomplishment after assembling each piece? Priceless. With the P2S, that joy only grew – more stable prints mean less rework, and smarter features let me focus on creativity, not troubleshooting.

The A1 is solid for beginners, but to help you decide if the P2S is worth the upgrade, I ran side-by-side tests and compared every key feature – here’s the unfiltered truth:

To keep things fair, I matched all settings on both printers: same model placement, identical support structures, and disabled auto-heat shutdown. Then I hit "print" at the same time:

• Print Time: The P2S estimated 33 minutes and finished in just over 30; the A1 estimated 41 minutes and wrapped up around 40. That’s an 8% speed boost for the P2S – not revolutionary, but definitely noticeable when you’re cranking out multiple prints.
• Print Quality: Visually, there’s almost no difference. Both printers deliver sharp details and smooth layers with PLA and PETG. If you’re just printing basic parts, the A1 gets the job done. But the P2S gets it done faster, with zero compromises on quality.

The P2S features upgraded flow calibration, servo motors for smoother filament feeding, and an ultra-flat heated bed (calibrated with a probe and calipers). Printing small, detail-heavy items like coin replicas – which demand perfect first layers and top surfaces – is consistent every time. After a few test runs, I was able to print in batches without issues – a game-changer for small workshops or anyone selling 3D printed goods. The P2S also supports batch engraving via its BirdsEye Camera, which automatically identifies and positions multiple identical items for efficient processing.

This is the P2S’s secret weapon, especially for college students or anyone who needs remote access. I’m stuck with a notoriously spotty campus Wi-Fi (great for intranet, terrible for external connections), but the P2S blew me away:

• File Transfer: No need for a local network – send print files directly over the public internet, no fuss. With the A1, I had to disconnect from public Wi-Fi and switch to the local network every time I wanted to send a file. Total hassle.
• Download Speed: The P2S’s hardware crushes the A1 when downloading files. No more repeated failed downloads or waiting forever for models to load.
  For remote workers, small business owners, or students, this alone makes the P2S worth the upgrade – it’s a modernized workflow that eliminates the need for physical SD cards.

Beyond specs, the P2S nails the little things that make daily use a breeze – something the A1 struggles with:

The A1’s open frame means temperature fluctuations (from AC, windows, or even fans) cause warping, detachment, or failed prints. The P2S’s enclosed chamber + adaptive air circulation + external cooling system fixes this:
I tested PLA prints with the chamber closed – a thermal camera showed the bed stayed steady at 55°C (131°F), while the chamber walls only hit 30°C (86°F). No overheating (like some enclosed printers), and zero warping or softening. Game over for the A1.

The P2S’s AI detection is a lazy person’s dream:

• If filament tangles ("3D printing spaghetti mode"), it stops immediately and sends a phone notification.
• It alerts you to leftover filament on the bed before you start printing.
  With the A1, I’d hover nearby, terrified of a mid-print failure. With the P2S? I start a print before bed, wake up to a finished model. I leave for work, come home to a perfect print. I’ve run back-to-back prints for days with no overheating, jams, or weird noises.

The A1’s open design lets PETG fumes linger – not terrible, but noticeable. The P2S’s built-in granulated coconut shell activated carbon filter traps VOCs and particles, making it way more indoor-friendly. Great for small apartments or home offices. But the exaust sitll be a issue so better to get the vent or exaust fan.

The P2S’s noise level is similar to the A1 – not silent. I keep mine in a storage room, and it’s totally unnoticeable through a wall. Also, regular maintenance is a must: silicone sleeves are consumables (replace periodically), and nozzles need cleaning with a needle if they clog. Standard 3D printer upkeep – nothing deal-breaking.

The P2S’s upgrades are practical, not flashy – it takes the A1’s fun and makes it reliable. Here’s who should (and shouldn’t) buy it:

• If you have a P1S: Skip it. The P2S is mostly incremental upgrades, not a huge leap.
• If you have an A1/A1 Mini: Upgrade if you love 3D printing and want faster prints, remote access, batch printing capability, and "set-it-and-forget-it" convenience.
• Beginners on a budget: Start with the A1 or A1 Mini. They deliver great print quality for the price (up to 500 mm/s / 19.69 in/s speed with AMS Lite multi-color support) – test the hobby before investing in the P2S.
• Students, small workshops, or remote users: Buy the P2S. The network stability, batch printing, and monitoring features will save you time and frustration.

At the end of the day, 3D printing’s magic isn’t about specs – it’s about turning ideas into physical objects. P2S vs A1:The A1 does that, but the P2S does it better: faster, more reliably, and with less hassle. It doesn’t reinvent the wheel – it polishes it until it’s perfect.
Hobbyist printers like the A1 are great for casual projects, but they require patience and troubleshooting. The P2S bridges the gap between hobby and professional use, offering pro-grade features at a mid-range price ($549 standalone, $799 combo). If you’re a casual hobbyist who prints occasionally, the A1 is more than enough. But if 3D printing is a passion, a side hustle, or a tool for your work? The P2S isn’t just an upgrade – it’s a must-have.
