Bambu Lab P1S vs A1

Last updated:

The P1S and A1 are not just two price points. The real split is enclosed CoreXY versus open-frame bed-slinger.

Short answer: Pick P1S for enclosed-material flexibility; pick A1 for a simpler open-frame setup and a lower-stress first printer.

Frequently Asked Questions

Is the P1S overkill for PLA?

Often, yes. It still prints PLA, but the enclosure is more valuable when you move beyond basic open-frame use.

Is the A1 only for beginners?

No. It is a capable open-frame printer, but it is designed to be approachable enough for first-time users.

Which one should a small workshop buy?

The P1S is the stronger workshop choice if material variety matters. The A1 is the better casual or classroom-style pick.
