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?
At its long-running $399 store price: yes, it is the cheapest enclosed Bambu, $150 under the P2S. The P2S ($549) is newer and faster; the P1S is the bargain. Only at the full $699 list price would we say skip it and 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 math changed in 2026: Bambu has been selling the P1S at $399 (an open-ended discount from the $699 list price), which makes it $150 cheaper than the P2S instead of $150 more. The P2S ($549) is still the better machine, faster at 600 mm/s with an improved motion system. But at current prices the P1S is the budget pick, not the overpriced one.
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
- You want the newer machine: the P2S ($549) is faster, but $150 more at current prices
- 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 added Lidar first-layer scanning and AI failure detection, but it is discontinued; its successor is the X2D at $649. If print consistency on long, complex jobs matters, the X2D is the upgrade to consider. 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.
Starter accessories for the P1S
What we would add to a new P1S in the first month.
Same 257 mm format as the stock P1S plate at a lower price. A spare plate means back-to-back prints.
Amazon →
Drop-in hardened high-flow nozzle for the P1S. Higher throughput, and it survives abrasive CF filament.
Amazon →
Community-standard replacement for the P1S AMS tubing when filament feed starts dragging.
Amazon →
The P1S enclosure does not protect filament from moisture. Drying PETG and nylon fixes stringing at the source.
