Open-frame CoreXY 256 mm cube printer, the un-enclosed sibling of the P1S, discontinued from Bambu Lab's own store by August 2026.
256 x 256 x 256 mm advertised. Bambu's own footnote limits the default printable height in Bambu Studio to 250 mm to avoid heatbed collisions, and warns that the collapsible filament-cutter stopper takes part of the printing area when popped out

| Property and unit | Published value and conditions | Sources and dates |
|---|---|---|
| Manufacturer & exact marketed model name (verify the exact product identity first) | Bambu Lab P1P. Bambu documents it alongside the P1S in a single two-column parameters table | 1 source |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | P1P is the open-frame version; the P1S is the same motion platform in an enclosure with plastic and glass panels. Bambu's own comparison table shows what the P1P lacks: control-board fan, chamber temperature regulator fan, auxiliary part-cooling fan and air filter are all listed "Optional" on the P1P and "Closed Loop Control"/"Activated Carbon Filter" on the P1S. The P1P is also lighter, 9.65 kg vs 12.95 kg, and 386 mm deep vs 389 mm. A P1P Enclosure Kit is sold as a spare part. Filament support differs accordingly: ABS/ASA are "Capable" on the P1P but "Ideal" on the P1S | 1 source |
| Market position: superseded? successor announced? | Superseded. No longer listed in the Bambu Lab US store 3D-printer collection in Aug 2026 (the collection carries A1, A1 mini, A2L, P1S, P2S, X2D, H2S, H2D, H2C); /products/p1p redirects to the collection page and only P1P spare parts remain in the store sitemap. No live first-party price could therefore be recorded | 2 sources |
Jericho’s riser provides a printed support between a glass top and the AMS. Confirm the surrounding enclosure, clearance and chosen print material for your setup rather than treating a printed riser as temperature-certified hardware.
Applies to: Creator lists P1P and P1S with a glass top. An open, stock P1P needs the corresponding enclosure/top arrangement.
The kit adds the enclosure and the cooling components specified in Bambu’s installation sequence. The documented firmware accessory flag lets a converted P1P use the corresponding P1S profiles.
Applies to: P1P enclosure conversion. The accessory flag requires P1 firmware 01.05.00.00 or later and Bambu Studio 1.8.1 or later; complete the hardware sequence first.

| Build volume X×Y×Z (mm) — advertised vs actually usable | 256 x 256 x 256 mm advertised. Bambu's own footnote limits the default printable height in Bambu Studio to 250 mm to avoid heatbed collisions, and warns that the collapsible filament-cutter stopper takes part of the printing area when popped out | 1 source |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 386 x 389 x 458 mm (P1P). Bambu prints P1P and P1S dimensions in the same cell - the P1S is 389 x 389 x 458 mm | 1 source |
| Net weight (kg) | 9.65 kg net, 14.30 kg gross | 1 source |
| Frame construction & material | Open frame; Bambu offers printable mod-plates for the side panels | 1 source |
| Enclosure: open / enclosed; panel material; door/lid | Open frame. An official P1P Enclosure Kit exists as a spare part, and the enclosed version of the same platform is sold as the P1S | 2 sources |

| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY driven by two stepper motors, each with its own belt to the printhead. Bambu's wiki states the P1P and P1S share the same motion system | 1 source
|
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Three leadscrews driven from a single stepper motor through a belt; the whole bed drops in Z. There is no motorised Z-tilt - bed tramming is by three manual knobs under the bed | 1 source
|
| Belts (type, width, e.g. Gates?) | Adjustable belt tensioners at the rear; a Belt Tension Monitor reports when tension drifts out of range | 1 source

Extrusion, heating, leveling and material handling.
Filament debris and wear in the extruder can contribute to clogs and inconsistent flow. Bambu documents inspection, cleaning and lubrication for the P1 extruder, with reassembly checks before printing again.
Applies to: P1P / P1S. Use the P1 electrical connectors and cleaning procedure; the X1 complete hotend is a different assembly.
Bambu lists a hardened extruder gear assembly for the P1 series as an alternative to the stock stainless assembly. Pair the drive-path change with a suitable hardened nozzle and the material’s requirements; the gears alone do not make every abrasive filament suitable.
Applies to: P1P / P1S gear assembly. Select the matching P1 hotend components; do not assume the P2S uses this assembly.

| Hotend design (proprietary/standard; quick-swap mechanism?) | All-metal all-in-one hotend: the nozzle is integrated into the heatblock and joined to the heatsink by a thin metal tube, so the hotend is replaced as a unit. 0.4 mm stainless-steel nozzle included; 0.2/0.6/0.8 mm optional | 2 sources

This guide presents the catalog’s sourced record for this exact model. Source dates belong to each reference; a page update does not mean every specification has been rechecked.
Prices are dated listing snapshots, with configuration, regional and sale conditions. They are not current offers. Unknown values remain unfilled.
Firmware, variants and available accessories can change. Read the original reference before making a purchase or planning a process.
Firmware, modifications and troubleshooting links are checked against the model and stated hardware or firmware revision. A creator’s compatibility claim is not a fit test by this site. Official troubleshooting describes a diagnostic route; individual reports do not establish a failure rate.
This review did not verify firmware customization or update guidance for this exact model. That is a research gap, not a claim that none exist.
