| Brand | Bambu Lab | QIDI |
| Class | COREXY | COREXY |
| 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] | QIDI Max4, sold as "Max4 High-Temp 3D Printer"[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] | Not published on QIDI's product page; the machine is listed as the current replacement for the discontinued X-Max 3 (checked Aug 2026)[2][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 | $1,099.00 standard on us.qidi3d.com against a $1,149.00 compare-at price, checked Aug 2026. Variants: Polar Cooler bundle $1,249.00 (was $1,348.00), Max4 Combo $1,249.00 (was $1,299.00), Combo + Polar Cooler $1,399.00[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] | Four variants at the US store: Standard, Polar Cooler bundle, Combo (adds QIDI Box), Combo + Polar Cooler. Direct replacement for the X-Max 3, which it differs from on every headline figure: 390x390x340 vs 325x325x315, 800 vs 600 mm/s, 370 vs 350 °C. Do not carry X-Max 3 specs across[2][5] |
| Market position: superseded?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 large-format flagship as of Aug 2026; QIDI's X-Max 3 page directs buyers here[2][5] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 256 x 256 x 256 mm advertised (manufacturer figure)[1] | 390 x 390 x 340 mm advertised[2][3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 389 x 389 x 457 mm[1] | 558 x 578 x 612 mm[3] |
| Net weight (kg) | 14.13 kg net[1] | 46.5 kg net[3] |
| 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] | Enclosed CoreXY chassis; QIDI does not publish a frame-material breakdown[2] |
| 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] | Fully enclosed with a 3-in-1 air filter (G3 pre-filter + H12 HEPA + coconut-shell activated carbon)[3] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | 65 °C, independent active chamber heating (manufacturer claim), with a 4-pin PWM chamber fan with RPM feedback[3] |
| 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[8][9] | CoreXY[3] |
| 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][9] | 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[8][9] | 2 mm lead Z screw with an anti-backlash nut[2] |
| Stepper motors (frame size, step angle, brand if known) | Not documented | FOC closed-loop stepper motors[3] |
| 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] | 800 mm/s (manufacturer claim, maximum)[3] |
| Max acceleration (claimed, mm/s²) | 20 m/s2 = 20000 mm/s2 max toolhead acceleration (manufacturer claim)[1] | 30,000 mm/s2 (manufacturer claim, maximum)[3] |
| 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] | 40 mm3/s rated flow (manufacturer claim)[3] |

| Gear ratio & drive gear material | Not documented | 8.9:1; drive gears hardened steel[3] |
| 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][8] | Multi-metal hotend with a ceramic heater and a 0.4 mm bimetal nozzle; ceramic throat[3] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max hot-end temperature[1] | <=370 °C claimed[2][3] |
| 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[10] | 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][8] | <=120 °C claimed on a 390 x 390 mm bed QIDI markets as ultra-uniform (no thermal imaging published)[2][3] |
| Bed surface (material, texture, coating), single/double-sided | Flexible steel plate; Cool Plate and Engineering Plate included, High Temperature Plate optional[1] | Aluminium plate with silicone heater; double-sided magnetic PEI build plate[3] |

| 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[12] | Not stated on the product page; QIDI Studio, PrusaSlicer and Orca are the supported slicers[3] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 5-inch 1280x720 touchscreen[1] | 5-inch touchscreen, 480 x 800[3] |

| 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] | Wi-Fi, LAN, USB[3] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Built-in 1920x1080 chamber monitoring camera[1] | AI camera with print-failure detection[2][3] |
| Power-Loss & Interruption Recovery | ||
| Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?) | Not documented | Power-loss recovery listed; mechanism not published[3] |
| 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, ABS, ASA, PETG, TPU, PA, PC, and glass- and carbon-fibre-filled polymers[3] |
| 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[10][12] | Not documented |
| 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[13] | 1-year coverage, lifetime tech guidance, 14-day no-reason return[2] |
| 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)[9] | Not documented |
Manufacturer claims, independent measurements, packages and test conditions retain their source wording. FDM linear speed and resin vertical speed use different units and are not directly comparable. Unknown values are marked “Not documented”. Prices and source dates remain historical snapshots; check the linked guide for product details. Differences highlight text, not a universal winner.
