| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Bambu Lab P1S. Store title: "Bambu Lab P1S 3D Printer"[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] |
| Street price (USD; dated snapshot per entry) | 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[4][1] | Not documented |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | 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][5] | 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][6][2] |
| Market position: superseded? successor announced? | Still sold in Aug 2026, but Bambu now markets the P2S as "The Classic Evolves" above it in the same enclosed-CoreXY slot[4][7] | 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[4] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 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] | 256 x 256 x 256 mm advertised (manufacturer figure)[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 389 x 389 x 458 mm; package 485 x 480 x 530 mm[1] | 389 x 389 x 457 mm[2] |
| Net weight (kg) | 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] | 14.13 kg net[2] |
| Frame construction & material | Steel chassis (shared with the P1P) inside plastic and glass 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 | 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] | 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][6] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY driven by two stepper motors, each with an independent belt to the printhead; the P1P and P1S share the same motion system[8] | 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[9][10] |
| 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][10] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | 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[8] | 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[9][10] |
| Belts (type, width, e.g. Gates?) | Rear adjustable belt tensioners with a Belt Tension Monitor[8] | 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 | ||

Hardened-steel nozzle as standard, 0.4 mm included, 0.2/0.6/0.8 mm optional[2][9] |
| 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[11] |
| 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][9] |
| 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 using three ceramic force (piezo) sensors mounted under the heatbed - Z homing is done by detecting the force of the nozzle contacting the bed[12][8] | 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[12][10][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[13] | 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[13] |
| Connectivity, UI & Camera | ||

| Materials Support | ||
| Officially supported filament list | Ideal: PLA, PETG, TPU, PVA, PET, ABS, ASA. Capable: PA, PC[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[11][13] |
