Bambu Lab's P2S slots in between the A1 and the X1C — a fully enclosed CoreXY machine with the new AMS 2 Pro, active filament drying, and RFID sync, starting at $549 standalone or $799 as a combo. We break down whether it's the smartest buy in the lineup.
The Bambu Lab P2S is the company's newest enclosed CoreXY printer, positioned to fill the gap between the open-frame A1/A1 Mini and the flagship X1-Carbon. It keeps the 256×256×256mm build volume and high-flow hotend from the P1S generation, but adds a redesigned chassis, quieter cooling, and — most importantly — full compatibility with the new AMS 2 Pro.
It ships in two configurations: a $549 standalone unit for people who already own an AMS, or a $799 combo that bundles one AMS 2 Pro unit. Given that an AMS 2 Pro alone costs close to $200, the combo is the better deal for almost everyone starting fresh.
The headline feature isn't the printer itself — it's what's attached to it. The AMS 2 Pro replaces the friction-wheel feeding of the original AMS with servo-driven motors on each spool, which Bambu claims cuts jams and feeding failures significantly, especially with flexible or brittle filaments like TPU and silk PLA.
It also adds an active air-vent drying system that circulates warm, dry air through the chamber continuously — not just when you trigger a manual dry cycle. For anyone printing nylon, PETG, or PVA supports in a humid climate, this alone can be worth the upgrade over a standalone AMS.
Finally, each spool now gets RFID tracking for Bambu-branded filament, syncing color, material type, and remaining length automatically into the slicer — handy for multicolor jobs where guessing wrong burns time and filament.
If you already own an A1, A1 Mini, or original AMS, the AMS 2 Pro units are backward compatible — you don't need a P2S to benefit from the drying and servo-feeding upgrades.
Out of the box, the P2S produces the same clean surface finish Bambu printers are known for — fine layer lines, minimal stringing on PLA and PETG, and consistent first layers thanks to the auto bed-leveling and flow calibration routines. We saw comparable results to the X1C on standard PLA and PETG prints, with the main gaps showing up on exotic materials.
Because it lacks the X1C's LiDAR-based first-layer inspection and AI error detection camera, the P2S is more hands-off-friendly for routine prints but offers less safety net on long, unattended multi-day jobs. For most hobbyists printing functional parts, miniatures, and multicolor models, that trade-off is easy to accept given the price gap.
Enclosure means better results with ABS and ASA than the open-frame A1 — warping on tall ASA prints was noticeably reduced compared to our A1 tests, though still not at X1C levels of chamber heating.
The redesigned cooling solution makes the P2S noticeably quieter than the original P1S — comfortable for a bedroom or office during daytime printing, though still audible overnight with the door closed.
| Printer | Price (combo) | Build Volume | AMS | Enclosed | Best For |
|---|---|---|---|---|---|
| Bambu Lab A1 | $549 (AMS Lite) | 256×256×256mm | AMS Lite | No | Budget multicolor |
| Bambu Lab P2S | $799 (AMS 2 Pro) | 256×256×256mm | AMS 2 Pro | Yes | Best value enclosed |
| Bambu Lab P1S | ~$799 (AMS Lite, older stock) | 256×256×256mm | AMS / AMS Lite | Yes | Discounted alternative |
| Bambu Lab X1C | ~$1,449 (AMS) | 256×256×256mm | AMS | Yes | Unattended, exotic materials |
The P2S essentially replaces the P1S at the same combo price point while adding the AMS 2 Pro's drying and servo feeding — making the P1S largely redundant unless you find clearance stock at a discount. Compared to the X1C, you give up LiDAR inspection, the AI camera, and a bit of build quality polish, but save roughly $650.
The P2S is the best all-around value in Bambu's current lineup. If your budget stretches to $799, it gives you an enclosed, AMS-equipped printer with meaningfully better filament handling than the A1 combo — for $650 less than an X1C. Unless unattended overnight printing or exotic engineering filaments are a priority, the P2S is the smarter buy.
