⚖️ Expert Verdict

Choosing between the Bambu Lab A1 and the P1S is a decision between budget-friendly innovation and enclosed versatility. Both printers share the same high-speed DNA and excellent software ecosystem, but the P1S is fully enclosed, making it capable of printing advanced materials like ABS or ASA that would warp on the open-frame A1. The A1, however, features a newer, swappable nozzle design and a quieter motor system. If you primarily print PLA and PETG for decorative items or toys, the A1 offers incredible value. But for engineers or makers who need a wider range of technical filaments and a protected printing environment, the P1S remains the more capable professional tool.

What Owners Are Saying?

Bambu Lab P1S

Oscar
"The enclosure is proper sorted. Printing ABS in my garden shed now with zero warping. Absolute unit."

Mia T.
"Strategic choice over the X1C. You get nearly all the performance for significantly less quid. The AMS is a must-have if you want to do any serious multi-material work."

William
"Setup was a doddle."

Grace S.
"Brilliant hardware, but the fan noise is right annoying if you're working in the same room. I’ve had to build a sound-dampening cabinet just to keep my sanity during the day."

Bambu Lab A1

Hobbyist_Harry
"Proper smart bit of kit. The active flow rate compensation means I don't have to faff about with calibrations anymore. It’s whisper quiet compared to my old Ender. The AMS Lite is a doddle to set up for multi-color prints. Absolute winner for any maker in 2026."

Daisy
"Fast and sharp. Quick-swap nozzles are a massive win for someone like me who switches between 0.4 and 0.6 often. Proper sorted."
