On non-abrasive materials, both printers deliver strong, comparable print quality thanks to the shared CoreXY design philosophy and AMS multi-color system. Speed differs on paper - the P2S is rated to 600 mm/s versus the P1S's 500 mm/s - but real-world quality at typical print speeds is close on both. If you only ever print in PLA, PETG, TPU, and ASA, the difference is marginal.
Bambu Lab P1S vs P2S (2026)
Bambu Lab P1S vs P2S compared in 2026. The P2S wins material flexibility and reliability, the P1S wins value. Here is which Bambu printer fits your shop.
Heads up: some links here pay us. If you buy through an EcoFlow or eufy link we may earn a commission, at no cost to you (that's Awin, in some countries). Amazon and other shop links pay us nothing right now. I haven't tested these products myself unless the page says so; the picks come from the specs and listings, and I'll tell you when I'm not sure.

Quick Answer
Bambu Lab P2S Combo wins overall
Print Quality and Speed
Material Flexibility
This is where the P2S earns its premium. Its hardened steel nozzle and hardened steel extruder gear ship standard, built for carbon-fiber-filled nylon and glass-filled materials that would chew through a brass nozzle in days. The P1S's current Amazon listing explicitly states Carbon/Glass Fiber Reinforced Polymer is "Not Recommended" on its stock hotend - an aftermarket hardened nozzle exists for the P-series, but the gears and other components remain stock, so frequent abrasive printing will wear it faster than a P2S built for the job.
Winner: Material Flexibility

Reliability and Hands-Off Use
The P2S's AI error detection uses a high-frequency eddy current flow sensor to catch clogs and grinding in real time, and its PMSM servo extruder delivers meaningfully more extrusion force than the P1S's. Both matter when you run prints overnight or hands-off in a workshop. The P1S's current listing does not detail an equivalent AI or advanced-sensor feature set - bed leveling is automatic and solid, but for production work the P2S earns the upgrade.

Value
At $549 with the AMS included, the P1S Combo remains an excellent printer-per-dollar value - and it is $300 cheaper than when this article first priced it. The P2S Combo at $769 is $220 more for features that benefit a minority of users. If you have never owned a 3D printer, start with the P1S. If you outgrow it, Bambu printers hold their resale value well enough that upgrading later costs relatively little.

Final Verdict
Save $220, Buy the P1S Unless You Print in Carbon Fiber
The P1S Combo is the right pick for almost everyone. Same enclosed-chamber design philosophy, same AMS multi-color system, same Bambu Studio software. Print quality is strong on PLA, PETG, TPU, and ASA. The P2S Combo is worth the $220 premium if you print regularly in carbon-fiber-filled or glass-filled materials, run a small production shop, or want AI-assisted error detection for hands-off reliability. For everyone else, save the money and put it toward filament, a second printer, or an aftermarket hardened nozzle later if you need one.
Frequently Asked Questions
Only if you print regularly in carbon fiber or glass-filled materials, run production prints overnight and want AI-assisted error detection, or have the budget and want the newer, faster machine. For most hobbyists, the P1S delivers strong print quality on standard materials for $220 less.
Bambu Lab's own current Amazon listing for the P1S explicitly states Carbon/Glass Fiber Reinforced Polymer is "Not Recommended" on its stock brass hotend. An aftermarket hardened steel nozzle exists for the P-series and can extend the hotend's life on abrasive materials, but the extruder gears are still stock, so heavy carbon fiber use will wear those too. If carbon fiber is a regular part of your workflow, the P2S ships with the hardened hardware standard.
Yes, though the units differ: the P1S Combo includes the original AMS, and the P2S Combo includes the newer AMS 2 Pro with active filament drying up to 65°C. Both support multi-color/multi-material printing and can be chained for more simultaneous spools.
Bambu Lab no longer sells the X1 Carbon as a new product - it is only available through Bambu's official refurbished store. Its role in the lineup (hardened components for abrasive materials, AI-assisted reliability) has been taken over by the P2S.
