ClassCOREXYCOREXY
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Bambu Lab X1E; spec PDF header "Bambu Lab X1E Technical Specification"[1]Prusa CORE One+ (Gen 2). Prusa's e-shop lists "Prusa CORE One+ (Gen 2)" and "Prusa CORE One+ (Gen 2) Assembly kit"[2][3]
Release date (announcement and actual shipping)Not documentedThe CORE One+ (Gen 2) refresh was announced on 13 August 2026, on sale immediately, with the first assembled units shipping at once and kits, upgrade kits and individual parts rolling out over the following weeks. It succeeds the CORE One and CORE One+ on the same platform[4]
Street price (USD; dated snapshot per entry)Not documented$1,202.78 assembled, $925.00 as an assembly kit, on prusa3d.com, Aug 2026. Bundles run to $1,301.85 with camera and advanced filtration. Prusa's own marketing table on the same page quotes "from $1,299" assembled, which does not match the live e-shop price[3][2]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Enterprise variant of the X1-Carbon, not a trim level. Differences from the X1C, from the two manufacturer spec sheets side by side: active chamber heating to 60 C (X1C has none), 320 C vs 300 C hot end, Smooth PEI plate included vs Cool/Engineering plates, G3+H12+carbon filter stack vs carbon filter only, Ethernet with a network kill switch, removable network module and 802.1X vs Wi-Fi only, 16 kg vs 14.13 kg, and 1400 W at 220 V / 750 W at 110 V vs 1000 W / 350 W[1][5]Three generations share the CORE One name: the original CORE One, the CORE One+, and the CORE One+ (Gen 2), with paid upgrade kits between them (CORE One+ to CORE One+ (Gen 2), and an MK4S to CORE One+ (Gen 2) conversion kit). The specifications recorded here are those published on Prusa's current CORE One+ (Gen 2) page and should not be assumed to hold for a first-generation CORE One. The INDX 4-tool and 8-tool machines are variants of the same product page, and the CORE One L is a larger, separate machine[2][3][6]
Market position: superseded? successor announced?Not present in the Bambu Lab US store 3D-printer collection in Aug 2026, which lists A1, A1 mini, A2L, P1S, P2S, X2D, H2S, H2D and H2C. Bambu sells business machines through a separate Business & Institution channel, so absence from the consumer collection is not proof of discontinuation; no live first-party price could be recorded[7]Current model and Prusa's mainstream enclosed machine, above the MK4S and below the CORE One L+[3]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable256 x 256 x 256 mm (manufacturer figure)[1]250 x 220 x 270 mm (manufacturer figure)[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)389 x 389 x 457 mm - identical to the X1-Carbon[1]415 x 444 x 555 mm (X x Y x Z)[2]
Net weight (kg)16 kg net (against 14.13 kg for the X1-Carbon)[1][5]22.5 kg[2]
Frame construction & materialSteel chassis with an aluminium and glass shell[1]All-steel exoskeleton (Prusa's own comparison wording, against "aluminium extrusions and frame" for the MK4S)[8]
Enclosure: open / enclosed; panel material; door/lidFully enclosed with a door sensor, and the only X1 with active chamber heating; the chamber is controlled to a maximum of 60 C[1]Fully enclosed with a door-open sensor and active chamber temperature control up to 55 C; HEPA/advanced filtration is an optional add-on[2][8]
Passive chamber temperature reached (if enclosed; measured values preferred)Actively heated chamber, maximum controlled temperature 60 C (manufacturer figure; not a passive measurement)[1]Active chamber heating, maximum 55 C (manufacturer figure)[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY, two stepper motors with one belt each (X1 series motion system)[9]CoreXY - stated as such in Prusa's own comparison table against the Cartesian MK4S[2]
X-axis guide type (rods / linear rails / V-wheels; size)Carbon X rail as on the X1-Carbon (X1 series toolhead and gantry)[10]Not documented
Z-axis: leadscrew count & type, sync mechanism, anti-backlashThree leadscrews belt-driven from a single stepper motor, whole bed moving in Z (X1 series)[9]Not documented
Stepper motors (frame size, step angle, brand if known)Not documented0.9 degree X and Y stepper motors[2]
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documentedTrinamic 2130[2]
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 on a 150x150 mm single-wall model in Bambu ABS at 280 C[1]Not documented
Extruder
Type (direct drive / bowden) & design nameDirect drive with hardened-steel extruder gears[1]Nextruder direct drive, E3D V6 compatible with an adapter; planetary gear system with a 10:1 ratio; aluminium heatsink and all-metal hotend[2]
Gear ratio & drive gear materialNot documented10:1 planetary gearbox[2]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)All-metal hotend with a hardened-steel nozzle; 0.4 mm included, 0.2/0.6/0.8 mm optional; built-in filament cutter[1]Quick-swap nozzle system; high-flow Prusa brass CHT 0.4 mm nozzle supplied. An optional HT hotend raises the ceiling to 400 C[2]
Max nozzle temp claimed AND firmware max temp limit (both values)320 C claimed max hot-end temperature - 20 C above the X1-Carbon[1][5]290 C claimed max nozzle temperature. Prusa's comparison table adds "400 C w/ HT" for the optional HT hotend, which its 13 August 2026 blog post says will only become available in September 2026 - so 400 C is a forthcoming option, not a shipping specification[2][4]
Heated Bed & Surface
Max bed temp claimed AND firmware limit110 C at 220 V, 120 C at 110 V max build-plate temperature[1]120 C max heatbed temperature[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[12]Open-source Prusa Buddy firmware. The source tree (prusa3d/Prusa-Firmware-Buddy on GitHub) explicitly covers the Original Prusa MINI/MINI+, MK4, XL and CORE One and was last pushed to in August 2026. Updates are applied from a USB drive, through Prusa Connect or through the Prusa mobile app[13][8]
Connectivity, UI & Camera
Display: size, type, touch?5-inch 1280x720 touchscreen[1]3.5-inch 65k-colour graphic screen with touch control[2]
On-device UI capabilities (model preview, per-object controls, etc.)Touchscreen plus app and PC application[1]On-device touch UI; remote monitoring and printing through Prusa Connect and the Prusa mobile app; firmware updates from USB, Prusa Connect or the app[2]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveWi-Fi (802.11 b/g/n) plus 100 Mbps full-duplex RJ45 Ethernet, a network kill switch covering both Wi-Fi and Ethernet, a removable network module and 802.1X network access control - the feature set that distinguishes the X1E from every other Bambu machine. 4 GB eMMC and a microSD card reader[1]Ethernet and Wi-Fi (NFC receiver plus an optional Wi-Fi module), USB drive for print files[2]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Built-in 1920x1080 chamber monitoring camera; micro-lidar also fitted[1]Optional in-chamber camera solution (Buddy3D camera bundle listed at $1,237.03 against $1,202.78 for the bare printer)[2][3]
Materials Support
Officially supported filament listOptimal: PLA, PETG, TPU, PVA, BVOH. Superior: ABS, ASA, PC, PA, PET and carbon/glass-fibre reinforced PLA, PETG, PA, PET, PC, ABS, ASA. Ideal: PPA-CF/GF, PPS, PPS-CF/GF[1]PLA, PETG, Flex, PVA, PC, PP, CPE, PVB, and - as advanced materials in the heated chamber - ABS, ASA, HIPS and PA[2]
Safety
Thermal runaway protection (verify in firmware source if at all possible)Firmware over-temperature protection is documented for the X1 series: HMS_0300-0200-0001-0003 fires when the heater runs at full power without reaching target in time. Thresholds are not published and the firmware is closed-source[14]The xBuddy platform carries hardware overcurrent protection that cuts heater and heatbed power above 15 A, and the firmware is open-source and auditable[15][13]
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]

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.
