| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Bambu Lab X1-Carbon (X1C); spec PDF header "Bambu Lab X1-Carbon - Technical Specifications"[1] | Original Prusa XL+, Single-Tool variant ("Prusa XL+ Single-Tool" in the e-shop variant data)[2][3] |
| Release date (announcement and actual shipping) | 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[4] | The XL+ refresh was announced on 13 August 2026, on sale immediately in all toolhead configurations, with assembled printers shipping later in August 2026 and upgrade kits for existing XL owners from around the end of August. The original Original Prusa XL predates it[5] |
| Launch MSRP (USD) | $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[4] | Not documented |
| Street price (USD; dated snapshot per entry) | Not documented | $2,128.70 on prusa3d.com, Aug 2026 (lowest listed price for the Single-Tool variant; the Enclosure bundle starts at $2,610.19)[2] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | 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[4][6][1] | The XL+ is sold in Single-Tool, Dual-Head and Five-Head variants at $2,128.70, $2,768.52 and $3,610.18 respectively (Aug 2026), plus Enclosure bundles and a Critical Infrastructure edition. The frame is the same in all of them - Prusa states the frame is ready for toolheads to be added at any time - so build volume, bed and electronics figures are shared and only the toolhead count and price differ. The XL+ is itself a revision of the Original Prusa XL: the older XL aligned toolheads with a mechanical pin, the XL+ uses a dedicated electronic sensor, adds a nozzle wiper and is claimed to print 10-15% faster[2][3] |
| Market position: superseded? successor announced? | 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[7] | Current model; an Original Prusa XL to Prusa XL+ upgrade kit is sold for existing owners[3] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 256 x 256 x 256 mm advertised (manufacturer figure)[1] | 360 x 360 x 360 mm, which Prusa states as 46.7 litres[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 389 x 389 x 457 mm[1] | About 700 x 900 x 720 mm (Prusa's own figure is approximate)[2] |
| Net weight (kg) | 14.13 kg net[1] | About 30 kg[2] |
| Frame construction & material | 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[1][4] | Aluminium extrusions and steel sheets (Prusa's comparison table for the XL)[8] |
| Enclosure: open / enclosed; panel material; door/lid | 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)[1][6] | Open frame. The Enclosure for Prusa XL+ is an optional add-on; Prusa says the printer is ready for chamber temperatures up to 60 C, that the new better-sealed enclosure reaches around 50 C on the printer's own waste heat, and that 60 C needs an upcoming chamber heater for which no shipping date has been given[2][5] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | 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] | CoreXY with 1.5 mm GT belts, Input Shaper and Phase Stepping[2] |
| X-axis guide type (rods / linear rails / V-wheels; size) | 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[4][10] | Not documented |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | 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] | Not documented |
| Belts (type, width, e.g. Gates?) | Not documented | 1.5 mm GT belts[2] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not published; no teardown source found that names the driver part[1] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 500 mm/s max toolhead speed (manufacturer claim); no independent measurement found[1] | Not documented |
| Max acceleration (claimed, mm/s²) | 20 m/s2 = 20000 mm/s2 max toolhead acceleration (manufacturer claim)[1] | Not documented |
| Max volumetric flow claimed (mm³/s) | 32 mm3/s claimed, measured by Bambu on a 150x150 mm single-wall model in Bambu ABS at 280 C[1] | Not documented |
| Vibration Compensation / Input Shaping | ||
| Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary) | Not documented | Input Shaper and Phase Stepping[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive with hardened-steel extruder gears; the service part is the "Hardened Steel Extruder Unit (X1 series)"[1] | Nextruder direct drive; each toolhead carries its own extruder, hotend, nozzle and filament[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | 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[1][9] | Quick-swap nozzles - 0.25 mm for detail, 0.6/0.8 mm for speed, hardened steel for abrasives, high-flow CHT for throughput; toolheads ship with high-flow nozzles[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max hot-end temperature[1] | 290 C claimed max nozzle temperature[2] |
| Heater cartridge power (W) | 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] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 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)[1][9] | 120 C max heatbed temperature[2] |
| Bed surface (material, texture, coating), single/double-sided | Flexible steel plate; Cool Plate and Engineering Plate included, High Temperature Plate optional[1] | Segmented heatbed of 16 individually controlled tiles across the 360 x 360 mm surface, so only the tiles under the part are powered; removable double-sided satin print sheet supplied[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | 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][1] | Load-cell sensor - the nozzle is the probe, which Prusa says automatically accounts for nozzle changes, surface textures and thermal expansion and removes manual Z-offsets. Toolhead-to-toolhead alignment on the XL+ uses a separate permanently mounted eddy-current Tool Offset Sensor, replacing the removable mechanical pin used on the original XL[2][5] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Yes - filament run-out sensor and door sensor; filament odometry only with an AMS fitted[1] | Filament sensors fitted; Prusa's comparison table lists two filament sensors for the XL[8] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Part-cooling fan, hot-end fan, control-board fan, chamber temperature regulator fan and auxiliary part-cooling fan, all closed-loop controlled[1] | 360-degree part cooling on each toolhead, new on the XL+ and matching the MK4S and CORE One arrangement; Prusa states it delivers more airflow and distributes it more evenly around the nozzle. Additional fans and heatsinks cool the electronics. Fan sizes are not published[2][5] |
| Chamber/exhaust fan & filtration (activated carbon / HEPA) | Chamber temperature regulator fan plus an activated-carbon filter[1] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | 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[1] | Custom 32-bit xBuddy electronics with STM32 (Prusa's comparison table for the XL)[8] |
| Total rated power draw | 100-240 VAC 50-60 Hz; 1000 W at 220 V, 350 W at 110 V[1] | Not documented |
| 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] | Open-source firmware - Prusa states "Firmware: Open-source; ships with the full current Prusa feature set", and the XL is covered by the prusa3d/Prusa-Firmware-Buddy source tree[2][14] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 5-inch 1280x720 touchscreen[1] | 3.5-inch 65k-colour screen with touch control (Prusa's comparison table for the XL)[8] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Touchscreen plus Bambu Handy app and Bambu Studio; on-device job control and monitoring[1] | On-device touch UI; Prusa Connect and the Prusa mobile app are optional - Prusa states the machine is fully offline capable[8][2] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | 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[1][6] | Ethernet, optional Wi-Fi; USB drive for print files. Prusa Connect optional and fully offline operation supported[2][8] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Built-in 1920x1080 chamber monitoring camera[1] | Not documented |
| Materials Support | ||
| Officially supported filament list | 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)[1] | PLA, PETG, ASA, ABS, PC, PA (nylon), TPU, PVA, HIPS, PP, CPE, PVB and carbon-fibre composites. Prusa states an open material policy - any brand of 1.75 mm filament, no chips and no subscriptions[2] |
| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | 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] | Open-source firmware on the xBuddy platform, which carries hardware overcurrent protection cutting heater and heatbed power above 15 A[15][14] |
| 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[16] | 2-year warranty for consumers in the EU, Liechtenstein, Switzerland, Norway and Iceland; 1 year for EU enterprises and 1 year for the rest of the world, which includes the United States. A printer bought from a reseller or privately carries 1 year from the original delivery date and is handled by the reseller. Prusa advertises 24/7 chat and e-mail support in seven languages[17][8] |
| Independently Measured Performance | ||
| Review scores from major outlets (list outlet + score + date) | Tom's Hardware: Editor's Choice, rating 4.5 out of 5 in the page's structured data (12 February 2024)[10] | Not documented |
