Bambu Lab P1S: problems, parts and running costs
Checked: 2026-10-17
Summary
The reviewer’s main complaints are noise, proprietary replacement parts and filament waste from the AMS on every color change, and the nozzle is not replaceable on its own, so a worn nozzle means swapping the whole hotend. Running costs are filament plus consumables, with hotend parts and build plates carrying no warranty; no yearly electricity or filament figure is reported. At the official $579.00 store price it is lower than its 2023 $699 launch price and is the pick for enclosed ABS/ASA printing without adding your own enclosure.
Common problems and fixes
- AMS wastes filament on color changes — the AMS purges filament on every color change, so multi-color printing costs extra material; buy the AMS only if multi-color matters. [5]
- Nozzle is not replaceable alone — a worn nozzle requires swapping the whole hotend, which involves several screws and delicate thermistor wires; the reviewer cited $9.99 for a stainless-steel hotend and $34.99 for a complete hotend assembly. [5]
- TPU jams in the extruder gears — TPU repeatedly hung up during loading and printed cleanly only at 40 mm/s in a 5 h 47 m print; load slowly and lower the speed for flexible filament. [5]
Parts and consumables
- Stainless-steel hotend — $9.99 per the reviewer’s 2023 citation (Tom’s Hardware); no updated price reported; hotend and nozzle parts carry no warranty. [5][4]
- Complete hotend assembly — $34.99 per the same 2023 citation; this is the part you swap when the nozzle wears out. [5]
Yearly running cost
Not enough data. Running costs beyond the printer are filament, replacement hotends and nozzles, build plates, all consumables with no warranty, plus any optional AMS unit or extra nozzles. [2][4]
When it is a good buy
- The official Bambu Lab US store lists the printer alone at $579.00, with the AMS Combo and AMS 2 Pro Combo bundles costing more; no current store price outside Bambu Lab was found. [2]
- Tom’s Hardware considered the P1S good value at its 2023 launch price of $699, so $579.00 is lower than launch. [5]
- Alternatives: the open-frame P1P ($599 at the 2023 review) is the better choice when you do not need the enclosure; the enclosed Creality K1 ($599 at the 2023 review) is the better choice when you want a slightly faster enclosed CoreXY; the Elegoo Neptune 3 Pro ($230 at the 2023 review) is the better budget pick.
