P1S vs P2S

Last updated daily price tracker

The P2S succeeded the P1S, but Bambu kept the P1S on sale, and at $349 it is still very much alive

Which one should I buy?

The P1S at $349 is $100 cheaper than the P2S at $449, which makes it the value pick and the P2S the performance pick. The P2S is newer and better in every spec that differs, so if $100 is not decisive for you, buy the P2S. If it is, the P1S still prints PLA, PETG, ABS and ASA in the same size; only carbon- and glass-filled filaments call for the P2S's hardened-steel nozzle.

Strengths: P1S vs P2S

P1S

  • $100 less than the P2S ($349 vs $449)
  • Proven platform with years of community support and firmware history

P2S

  • Newer platform, but $100 more than the P1S ($449 vs $349)
  • 600mm/s vs 500mm/s, 20% higher rated top speed (with the standard hotend, Bambu Studio's 0.20 mm Standard profiles print walls and infill at the same speeds on both; the P2S travels faster)
  • Up to 8 AMS units (4 AMS 2 Pro + 4 AMS HT, 20 slots) vs 4 units on the P1S
  • Newer hardware platform, longer software support lifecycle
  • Refined enclosure and airflow over the P1S

The P2S is the successor, not a sidegrade

Bambu released the P2S as the P1S's successor and kept the P1S on sale: it prints faster and takes twice as many AMS units (up to 8 with 20 slots vs 4 on the P1S; both run the AMS 2 Pro and AMS HT). Pricing has since flipped the order. The P1S sells for $349, $100 under the P2S, which makes the P1S the budget buy and the P2S the performance buy. If the newer motion system and the extra AMS capacity matter to you, that $100 is well spent.

Both printers share the same build volume and enclosure philosophy. Neither has Lidar. The X1C had it, but Bambu ended X1C production on March 31, 2026, and new units are down to leftover distributor stock. For engineering materials, look at the X2D or the H2S instead.

Get the P1S if...

  • You want the same build volume and PLA/PETG/ABS/ASA printing for $100 less
  • Someone is giving it to you

Get the P2S if...

  • You're buying new and the extra $100 is not decisive for you
  • You want the newer, faster P-series machine
  • You want faster prints and longer platform support

What about P1S deals and used market?

The used market has been overtaken by Bambu itself: a new P1S costs $349 with a full warranty, so used units only make sense well under $270.

  1. Bambu US store price update: P1S $349 (was $399), P2S $449 (was $549).
  2. P1S price back at $399 after the $369 cut; the gap to the P2S is $150 again.
  3. P1S price now $369 (was $399), $180 under the P2S; the P2S speed pro now says Bambu Studio's 0.20 mm Standard profiles print walls and infill at the same speeds on both, the P2S only travels faster.

  1. Spec table: the P2S chamber value is back, now listed as passive at ~50°C (was enclosed, not actively heated).
  2. P2S AMS advantage now up to 8 units (4 AMS 2 Pro plus 4 AMS HT, 20 slots) vs 4 on the P1S (was AMS 2.0 reliability).
  3. AMS support corrected: both take the AMS, AMS 2 Pro and AMS HT (P1S 4 units, P2S up to 20 slots), so full-AMS compatibility is no longer a P1S advantage; X1C production ended March 31, 2026.
  4. Materials spelled out: the P1S prints PLA, PETG, ABS and ASA, and only carbon- and glass-filled filaments call for the P2S's hardened-steel nozzle (was the same materials).
  5. Who-should-buy lists updated: pick the P1S for the same materials and build volume at $150 less (was only if significantly discounted secondhand or on clearance).
  6. P1S price back at $399 after the $359 Fall Sale price; the gap to the P2S is $150 again.
  7. P1S price now $359 in the Fall Sale (was $399), $190 under the P2S; used units now only make sense well under $270 (was $300).
  8. P1S price back at $399 after the $369 cut, $150 under the P2S; the $699 list-price comparison removed.
  9. P1S price now $369 (was $399); the gap to the P2S is $180.
  10. Verdict changed: Bambu's open-ended discount puts the P1S at $399 (list $699), $150 under the P2S, so the P1S is now the value pick and the P2S the performance pick.
  11. Chamber temperatures removed: both printers are now listed as enclosed, not actively heated (was passive ~45°C for the P1S and ~50°C for the P2S).
