| Identity & Market | ||
| 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] | Bambu Lab P1S. Store title: "Bambu Lab P1S 3D Printer"[1] |
| Street price (USD; dated snapshot per entry) | Not documented | From $369.00 (base P1S) on the Bambu Lab US store, Aug 2026, against a stated typical price of $399.00; with the P1S AMS 2 Pro Combo variant selected the same page shows $539.00 against a typical $579.00[2][1] |
| 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] | Enclosed version of the P1P and mechanically the same motion platform. Three SKUs on one product page: P1S, P1S AMS Combo and P1S AMS 2 Pro Combo (the AMS 2 Pro adds active filament drying). Sibling figures that get mixed up: net weight 12.95 kg (P1S) vs 9.65 kg (P1P); depth 389 mm vs 386 mm; ABS/ASA Ideal (P1S) vs Capable (P1P). Also distinct from the 2026 P2S, which is a different machine (600 mm/s, 110 C bed, 5-inch touchscreen, 14.9 kg)[1][3] |
| Market position: superseded?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 | Superseded.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][1] | Still sold in Aug 2026, but Bambu now markets the P2S as "The Classic Evolves" above it in the same enclosed-CoreXY slot[2][4] |
| Physical & Frame | ||
| 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] | 256 x 256 x 256 mm advertised. Bambu's own footnote sets the default printable height in Bambu Studio to 250 mm to prevent heatbed collisions, and notes the collapsible filament-cutter stopper occupies part of the print area when popped out[1] |
| 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] | 389 x 389 x 458 mm; package 485 x 480 x 530 mm[1] |
| Net weight (kg) | 9.65 kg net, 14.30 kg gross[1] | 12.95 kg net, 17.60 kg gross; the AMS Combo ships at 21.60 kg gross and the AMS 2 Pro Combo at 21 kg gross[1] |
| Frame construction & material | Open frame; Bambu offers printable mod-plates for the side panels[1] | Steel chassis (shared with the P1P) inside plastic and glass panels[1] |
| 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[1][2] | Fully enclosed - plastic and glass panels with a glass front door and lid, plus an activated-carbon air filter. No active chamber heater; the chamber temperature regulator fan is closed-loop controlled[1] |
| Kinematics & Motion Hardware | ||
| 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[5] | CoreXY driven by two stepper motors, each with an independent belt to the printhead; the P1P and P1S share the same motion system[5] |
| 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[5] | Three leadscrews belt-driven from a single stepper motor, whole bed moving in Z; manual tramming by three knobs under the bed, no motorised Z-tilt[5] |
| Belts (type, width, e.g. Gates?) | Adjustable belt tensioners at the rear; a Belt Tension Monitor reports when tension drifts out of range[5] | Rear adjustable belt tensioners with a Belt Tension Monitor[5] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 500 mm/s max toolhead speed (manufacturer claim); no independent measurement found[1] | 500 mm/s max toolhead speed (manufacturer claim); no independent measurement found[1] |
| Max acceleration (claimed, mm/s²) | 20 m/s2 = 20000 mm/s2 max toolhead acceleration (manufacturer claim)[1] | 20 m/s2 = 20000 mm/s2 max toolhead acceleration (manufacturer claim)[1] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive; Bambu sells a "Stainless Steel Extruder Unit (P1 series)" as the service part[5] | Direct drive; the service part is the "Stainless Steel Extruder Unit (P1 series)"[5] |
| Hotend & Nozzle | ||
| 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[1][5] | All-metal all-in-one hotend with the nozzle integrated into the heatblock, replaced as a unit; 0.4 mm stainless-steel nozzle included, 0.2/0.6/0.8 mm optional[1][5] |
