P1S
ABS/ASA capableFully enclosed, sealed, with HEPA and carbon filtration. The P1S is where Bambu's lineup gets serious about engineering materials. ABS, ASA, and PA-GF all work reliably in the passive-heated enclosure.
Should I buy the P1S?
Probably not new: the P2S ($549) is faster, cheaper, and better in every spec that differs. If you find a heavily discounted P1S, it's still a solid machine; otherwise buy the P2S.

The P1S is a solid machine that established Bambu's credibility in the enclosed-printer market. The fully sealed enclosure, combined with the 110°C bed and passive chamber heating (typically reaching 40–50°C), makes ABS, ASA, and glass-filled PA genuinely reliable. The camera is included, so you can monitor prints remotely.
The honest caveat: the P2S is better and $150 cheaper. At $549 vs $699, faster at 600 mm/s, with an improved motion system, the P2S is the current equivalent. There is no reason to pay more for the P1S unless you find it significantly discounted.
Pros
- Fully sealed enclosure: reliable ABS/ASA printing
- HEPA + carbon filtration (safe for enclosed spaces)
- 110°C bed: good for engineering materials
- AMS compatible, up to 16 colors
- Camera included for remote monitoring
- Proven, well-documented platform
- Large community and third-party support
Cons
- P2S is better and $150 cheaper, buy that instead
- 300°C hotend cap: no PC or high-temp PA
- Passive chamber only, no active heating
- 500 mm/s max (P2S does 600 mm/s)
- No Lidar (X1C feature only)
- AMS sold separately ($300+)
| Material | Support | Notes |
|---|---|---|
| PLA / PLA+ | Excellent | Works perfectly. |
| PETG | Excellent | Use glue stick on PEI. Seal chamber first for best results. |
| ABS | Excellent | Enclosure makes this reliable. Pre-heat chamber for 15 min. |
| ASA | Excellent | ASA is actually easier than ABS. Great results. |
| TPU | Supported | Direct drive handles TPU well. |
| PA-GF / PA6 | Workable | Needs dry filament, pre-heated chamber, hardened nozzle. Passive chamber is marginal for some PA grades. |
| PLA-CF / PETG-CF | Hardened nozzle needed | Abrasive. Use hardened steel or tungsten nozzle. |
| PC (Polycarbonate) | Not supported | 300°C hotend insufficient. Needs 350°C+ for reliable PC. |
| PA-CF (high-temp) | Not recommended | Passive chamber insufficient. Use H2S for serious PA-CF work. |
ABS/ASA pre-heat: Before starting a print, heat the bed to 100°C and let the chamber reach temperature for 15–20 minutes. This prevents corner lifting dramatically.
LAN mode: Enable LAN Only + Developer Mode in Settings for Orca Slicer. Use the local IP and access code.
Filter maintenance: Replace HEPA and carbon filters periodically. Bambu recommends every 3 months with regular use. Clogged filters reduce effectiveness.
P1S or P2S? P2S every time for new buyers. It's faster, cheaper, and has a slightly better chamber. Only buy the P1S if you find it at a significant discount.
P1S or X1C? The X1C adds Lidar first-layer scanning and AI failure detection for $500 more. Worthwhile if print consistency on long, complex jobs matters. Otherwise the P1S (or P2S) is sufficient.
Does the AMS work with the P1S? Yes, the full AMS (not AMS Lite). Up to 4 AMS units, 16 colors per print. AMS is sold separately (~$299–$349) or in combo packs.
Is the passive chamber enough for PA? For PA6-GF and similar grades, workable with dry filament. For demanding PA-CF grades, the active 65°C chamber of the H2S is recommended.
