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]Original Prusa MK4[2]
Release date (announcement and actual shipping)Not documentedAnnounced 29 March 2023 with assembled printers shipping immediately from stock; kits opened for ordering about two weeks later[2]
Launch MSRP (USD)Not documented1099 USD assembled, 799 USD as a kit, VAT included, at launch[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network module and 802.1X vs Wi-Fi only, 16 kg vs 14.13 kg, and 1400 W at 220 V / 750 W at 110 V vs 1000 W / 350 W[1][3]Superseded by the MK4S, which is the same machine plus a 360-degree turbine part-cooling fan, a high-flow CHT nozzle and firmware/profile work; Prusa sold a 99 USD MK4-to-MK4S upgrade kit and automatically converted unshipped MK4 orders to the S version. The MK3.5 and MK3.9 upgrades convert an MK3S+ to part of the MK4 electronics stack but are not an MK4[4][2]
Market position: superseded?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[5]Discontinued. No MK4 appears in Prusa's Aug 2026 3D-printer listing, and the MK4 product-page slugs redirect to the MK4S page, so no live first-party price could be recorded[6][4]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable256 x 256 x 256 mm (manufacturer figure)[1]250 x 210 x 220 mm (manufacturer figure)[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)389 x 389 x 457 mm - identical to the X1-Carbon[1]Not documented
Net weight (kg)16 kg net (against 14.13 kg for the X1-Carbon)[1][3]Not documented
Frame construction & materialSteel chassis with an aluminium and glass shell[1]Die-cast aluminium frame - Prusa replaced the MK3S+'s cut-aluminium frame for the MK4, keeping only the Y-axis profiles, some bearings, the heatbed and the power supply[2]
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]Open frame; the Original Prusa Enclosure is an optional add-on[2]
Passive chamber temperature reached (if enclosed; measured values preferred)Actively heated chamber, maximum controlled temperature 60 C (manufacturer figure; not a passive measurement)[1]Not documented
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY, two stepper motors with one belt each (X1 series motion system)[7]Cartesian bed-slinger of the Prusa i3 family - Prusa's MK4 announcement records that the MK3S+ Y-axis profiles and heatbed were carried over[2]
X-axis guide type (rods / linear rails / V-wheels; size)Carbon X rail as on the X1-Carbon (X1 series toolhead and gantry)[8]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)[7]Not documented
Stepper motors (frame size, step angle, brand if known)Not documented400-step (0.9 degree) stepper motors, stated by Prusa to prevent vertical fine artefacts[2]
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documentedTrinamic TMC2130-LA silent stepper drivers on the xBuddy board[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 with a planetary gear system, 1:10 gearbox ratio; aluminium heatsink, all-metal hotend, no PTFE tube in the filament path[2]
Gear ratio & drive gear materialNot documented1:10 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, 0.4 mm default, other diameters supported[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][3]300 C claimed max hotend temperature in Prusa's MK4 announcement table - note the MK4S product page publishes 290 C for the same hotend family[2][9]
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[11]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[12][9]
Connectivity, UI & Camera
Display: size, type, touch?5-inch 1280x720 touchscreen[1]3.5-inch 65k-colour graphic screen[2]
On-device UI capabilities (model preview, per-object controls, etc.)Touchscreen plus app and PC application[1]On-device colour UI with one-click printing and status LEDs; Prusa Link is integrated and Prusa Connect adds remote printing[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 built in, optional ESP Wi-Fi module delivered with the printer, USB drive; print files can also arrive over LAN or the internet via Prusa Connect[2]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Built-in 1920x1080 chamber monitoring camera; micro-lidar also fitted[1]Not documented
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]Prusa's launch table says "any thermoplastic including Nylon and Polycarbonate"; the enclosure is still needed in practice for ABS/ASA-class materials[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[13]xBuddy hardware overcurrent protection disconnects heater and heatbed power when total current exceeds 15 A; firmware is open-source and auditable[2][12]
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[14]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[15][9]

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.
