P1S and P2S share the same nominal 256 × 256 × 256 mm volume. Compare P2S around maintenance, monitoring features and the AMS package. If a P1S already fits your work, additional build space is not a reason to upgrade.
Collect both offers on the same day for the same US delivery address. Record the printer, AMS generation, required accessories, shipping and sales tax. Pick a task that matters to you, such as changing a nozzle, preparing a material or monitoring a job. Read the instructions for that task to understand the practical difference. Comparing printer-only prices can hide a substantial package difference.
If you already own a P1S, list the interventions you would like to reduce and how frequently they occur. Bambu Lab describes new features on P2S, but we have no comparative measurements of failures, noise or time saved. We therefore do not assume the replacement will pay for itself. Keep the complete cost and your decision criteria in the buying checklist.
256 × 256 × 256 mm
The same nominal volume as the A1, with an enclosure and a different motion system.
Check the precise AMS version, adapters and accessories included. Enclosure alone does not establish material suitability.

256 × 256 × 256 mm
The enclosed frame, hotend up to 300°C and bed up to 110°C support a broader material discussion than an open-frame machine.
AMS 2 Pro and drying capabilities depend on the package selected. Advertised automation is not a measured reliability score.
