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 X-Max 3, listed by QIDI as "Qidi Tech X-Max 3 3D Printer" and in navigation as X-Max3[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 by QIDI; the product page carries a discontinuation notice rather than a launch date (checked Aug 2026)[2]
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$899.00 (from a $999.00 sale reference) on us.qidi3d.com but marked Sold Out and discontinued, checked Aug 2026. 3D Printers Online Store lists $1,099 USD, also out of stock[2][5]
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]Same-generation siblings X-Plus 3 (280x280x270, 500 mm/s, 800 W) and X-Smart 3 (175x180x170, no chamber heating, 300 °C, 350 W). All three share the Cortex-A53 1.5 GHz / 1 GB DDR3 / 8 GB eMMC control board, so shared-board specs are not evidence of shared print specs. Replaced by the Max4[3][7][8][9]
Market position: superseded?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[10]Discontinued and out of production; QIDI directs buyers to the Max4[2]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable256 x 256 x 256 mm advertised (manufacturer figure)[1]325 x 325 x 315 mm advertised[2][3][5]
Machine footprint (mm) & clearance needed (cable/spool overhang)389 x 389 x 457 mm[1]553 x 553 x 601 mm[3][5]
Net weight (kg)14.13 kg net[1]30.2 kg net[3][5]
Frame construction & materialWelded 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, fully assembled from the factory. QIDI does not publish a frame-material breakdown[3]
Enclosure: open / enclosed; panel material; door/lidFully 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 chamber circulation blower and activated-carbon air filter[3]
Passive chamber temperature reached (if enclosed; measured values preferred)Not documented65 °C maximum, independent chamber heating (manufacturer claim)[2][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[11][12]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][12]Linear optical axis (polished steel rod) of high-strength steel[3]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashThree 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[11][12]Double Z axis[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]<=600 mm/s (manufacturer claim)[2][3][5]
Max acceleration (claimed, mm/s²)20 m/s2 = 20000 mm/s2 max toolhead acceleration (manufacturer claim)[1]20,000 mm/s2 (manufacturer claim)[2]
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]35 mm3/s extruder flow (manufacturer claim)[3]
Extruder
Type (direct drive / bowden) & design nameDirect drive with hardened-steel extruder gears; the service part is the "Hardened Steel Extruder Unit (X1 series)"[1]High-flow direct-drive extruder; QIDI states a 9.5:1 gear ratio for this model[2][3]
Gear ratio & drive gear materialNot documented9.5:1[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][11]Ceramic heating core. Two interchangeable nozzle-head sets shipped: copper alloy for standard materials, hardened steel for abrasives. 0.4 mm stock, 0.2/0.6/0.8 mm optional[2][3]
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max hot-end temperature[1]<=350 °C claimed[2][3][5]
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[13]Not documented
Heated Bed & Surface
Max bed temp claimed AND firmware limit110 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][11]<=120 °C claimed[3][5]
Bed surface (material, texture, coating), single/double-sidedFlexible steel plate; Cool Plate and Engineering Plate included, High Temperature Plate optional[1]Double-sided flexible magnetic plate (QIDI's "HF" plate)[2][3]
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[14][12][1]Automatic levelling via Klipper adaptive meshing; probe technology not named by QIDI[2]
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 detection fitted; type and location not published[3]

Materials Support
Officially supported filament listPLA, 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]ABS, PLA, PETG, TPU, nylon, carbon fibre, PC[5]
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[13][15]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[16]1-year coverage[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)[12]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.
