| 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 X1-Carbon (X1C); spec PDF header "Bambu Lab X1-Carbon - Technical Specifications"[2] |
| Release date (announcement and actual shipping) | Not documented | Announced 23 May 2022; Kickstarter pre-orders opened 31 May 2022 and ran to 30 June 2022, with shipment stated to start immediately after the campaign closed in July 2022[3] |
| Launch MSRP (USD) | Not documented | $1199 MSRP for the X1-Carbon, $1449 for the X1-Carbon Combo (with AMS); Kickstarter early-bird was $849 / $999. The non-carbon X1 was $999 MSRP[3] |
| 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] | Three related SKUs at launch: X1 (steel nozzle, no carbon rails, $999), X1-Carbon ($1199) and X1-Carbon Combo (X1C + AMS, $1449). The X1E is a separate business-focused machine, not a trim level: it adds active chamber heating to 60 C, Ethernet with 802.1X, a HEPA/carbon filter stack, a 320 C hot end and a Smooth PEI plate, and weighs 16 kg against the X1C's 14.13 kg[3][4][2] |
| Market position: superseded?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 | Superseded.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[5][1] | Discontinued. In Aug 2026 the X1-Carbon is absent from the Bambu Lab US store 3D-printer collection, /products/x1-carbon redirects to that collection, and the regional stores (EU, Asia, AU, CA) redirect to the same place; only X1-series spare parts remain in the store sitemap. Its market slot is now held by the X2D. No live first-party price could be recorded[5] |
| 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 (manufacturer figure)[2] |
| 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 457 mm[2] |
| Net weight (kg) | 9.65 kg net, 14.30 kg gross[1] | 14.13 kg net[2] |
| Frame construction & material | Open frame; Bambu offers printable mod-plates for the side panels[1] | Welded steel chassis with an aluminium and glass shell - Bambu's launch release contrasts the welded chassis with the bolted frames of most consumer machines[2][3] |
| 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][5] | Fully enclosed, aluminium and glass, with a door sensor and an activated-carbon air filter. No active chamber heating (that is the X1E's addition)[2][4] |
| 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[6] | CoreXY driven by two stepper motors with one belt each; Tom's Hardware confirms the XY gantry is fixed in Z and the platform drops during printing[7][8] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | Carbon-fibre X rail - Bambu's launch release calls it a "featherlight full-carbon X rail" and credits it for the 20000 mm/s2 acceleration figure; Tom's Hardware describes carbon-fibre rails on the X axis[3][8] |
| 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[6] | Three leadscrews driven from a single stepper motor through a belt, moving the whole bed in Z; three manual levelling knobs under the bed, no motorised Z-tilt[7][8] |
| Belts (type, width, e.g. Gates?) | Adjustable belt tensioners at the rear; a Belt Tension Monitor reports when tension drifts out of range[6] | Not documented |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | Not published; no teardown source found that names the driver part[2] |
| 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[2] |
| 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)[2] |
| Max volumetric flow claimed (mm³/s) | Not documented | 32 mm3/s claimed, measured by Bambu on a 150x150 mm single-wall model in Bambu ABS at 280 C[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive; Bambu sells a "Stainless Steel Extruder Unit (P1 series)" as the service part[6] | Direct drive with hardened-steel extruder gears; the service part is the "Hardened Steel Extruder Unit (X1 series)"[2] |
| 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][6] | All-metal all-in-one hotend - nozzle integrated into the heatblock, joined to the heatsink by a thin metal tube, replaced as a unit. Hardened-steel nozzle as standard, 0.4 mm included, 0.2/0.6/0.8 mm optional[2][7] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max hot-end temperature[1] | 300 C claimed max hot-end temperature[2] |
| Heater cartridge power (W) | Not documented | Not published. Bambu's own X1-series troubleshooting page states the ceramic heater measures about 12 ohm at room temperature, which at the 24 V rail works out to roughly 48 W - a derived figure, not a manufacturer rating[9] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 100 C max build-plate temperature[1] | 110 C at 220 V, 120 C at 110 V max build-plate temperature (Bambu's spec sheet gives both; the wiki text quotes 110 C)[2][7] |
| Bed surface (material, texture, coating), single/double-sided | Textured PEI plate; Cool Plate, Engineering Plate and High Temperature Plate compatible[1] | Flexible steel plate; Cool Plate and Engineering Plate included, High Temperature Plate optional[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Nozzle-touch probing against three ceramic force (piezo) sensors under the heatbed: Z homing works by detecting the force of the nozzle contacting the heatbed. Three manual levelling knobs are also fitted[10][6] | Nozzle-touch probing on three ceramic force (piezo) sensors under the heatbed, plus a separate toolhead micro-lidar (advertised 7 um resolution) used for first-layer inspection and flow calibration rather than for bed mesh[10][8][2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Yes - filament run-out sensor[1] | Yes - filament run-out sensor and door sensor; filament odometry only with an AMS fitted[2] |
| Multi-material/multi-color capability or official upgrade path | Compatible with AMS and the AMS hub, up to 16 colours with four AMS units[6] | Not documented |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Part-cooling fan fitted; the control-board fan, chamber temperature regulator fan and auxiliary part-cooling fan that the P1S has under closed-loop control are all listed as Optional on the P1P[1] | Part-cooling fan, hot-end fan, control-board fan, chamber temperature regulator fan and auxiliary part-cooling fan, all closed-loop controlled[2] |
| Chamber/exhaust fan & filtration (activated carbon / HEPA) | Not documented | Chamber temperature regulator fan plus an activated-carbon filter[2] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | Motion controller dual-core Cortex-M4; application processor quad ARM A7 at 1.2 GHz with a 2 TOPS NPU; 4 GB eMMC. Board model and chip markings not published[2] |
| Total rated power draw | Not documented | 100-240 VAC 50-60 Hz; 1000 W at 220 V, 350 W at 110 V[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Closed-source proprietary firmware - not a Klipper or Marlin derivative, and no printer-firmware source is published. The bambulab GitHub organisation carries 11 repositories (Bambu Studio, wxWidgets/boost/ffmpeg forks, the wiki); none is printer firmware. Updates are delivered over the air via Bambu Studio / Bambu Handy[11] | Closed-source proprietary firmware - not a Klipper or Marlin derivative, and no printer-firmware source is published. The bambulab GitHub organisation carries 11 repositories (Bambu Studio, wxWidgets/boost/ffmpeg forks, the wiki); none is printer firmware. Updates are delivered over the air via Bambu Studio / Bambu Handy[11] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 2.7-inch 192x64 monochrome screen, not a touchscreen - control is by button, app or PC application[6] | 5-inch 1280x720 touchscreen[2] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Button-driven on-device UI on a 192x64 monochrome panel; most interaction is expected to happen in Bambu Studio or Bambu Handy[6] | Touchscreen plus Bambu Handy app and Bambu Studio; on-device job control and monitoring[2] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi, Bluetooth and Bambu-Bus; microSD card storage; 5 V/1.5 A USB output power[6] | Wi-Fi 2.4 GHz (802.11 b/g/n) and Bambu-Bus; 4 GB eMMC plus a microSD card reader. No Ethernet - that is the X1E's addition[2][4] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Low-rate chamber monitoring camera, 1280x720 at 0.5 fps, timelapse supported - the 0.5 fps figure is Bambu's own and is far below video rate[1] | Built-in 1920x1080 chamber monitoring camera[2] |
| Materials Support | ||
| Officially supported filament list | Ideal: PLA, PETG, TPU, PVA, PET. Capable: PA, PC, ABS, ASA - the open frame is the limiting factor, and the same table upgrades ABS/ASA to Ideal for the enclosed P1S[1] | PLA, PETG, TPU, ABS, ASA, PET supported; PA and PC listed Ideal; carbon/glass-fibre reinforced polymers listed Ideal (the machine ships with a hardened-steel nozzle)[2] |
| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | Not documented | A firmware over-temperature protection exists and is documented by Bambu: HMS_0300-0200-0001-0003 is raised when the heater runs at full power but fails to bring the nozzle to target within time, which Bambu describes as "a safety mechanism designed to prevent potential damage to the device or other risks in case of a temperature control failure". Firmware is closed-source, so the exact thresholds cannot be verified[9][11] |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | 2-year limited warranty for consumers in the US, Canada, the EU, Switzerland, Norway and Iceland; 1 year in the rest of the world. Bambu Lab's own policy records the US/Canada term as a 2026 extension from one year to two[12] | 2-year limited warranty for consumers in the US, Canada, the EU, Switzerland, Norway and Iceland; 1 year in the rest of the world. Bambu Lab's own policy records the US/Canada term as a 2026 extension from one year to two[12] |
| Independently Measured Performance | ||
| Review scores from major outlets (list outlet + score + date) | Not documented | Tom's Hardware: Editor's Choice, rating 4.5 out of 5 in the page's structured data (12 February 2024)[8] |
