|---|---|---|
| Identity | ||
| Brand | Bambu Lab | Prusa Research |
| Class | COREXY | BEDSLINGER |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Bambu Lab X2D; spec PDF header "X2D Spec"[1] | Original Prusa MK4[2] |
| Release date (announcement and actual shipping) | Not documented | Announced 29 March 2023 with assembled printers shipping immediately from stock; kits opened for ordering about two weeks later[2] |
| Launch MSRP (USD) | Not documented | 1099 USD assembled, 799 USD as a kit, VAT included, at launch[2] |
| Street price (USD; dated snapshot per entry) | From $649.00 on the Bambu Lab US store, Aug 2026; the compare page shows the same $649 figure[3] | Not documented |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Dual-nozzle machine: a main hotend with a permanent-magnet synchronous extruder motor and an auxiliary hotend with a plain stepper motor, so the two nozzles are not equivalent. Bambu publishes four different build volumes depending on which nozzle is used, and a shorter list of materials for the auxiliary nozzle. Physical dimensions (392x406x478 mm) are shared with the P2S but the X2D is 16.25 kg against the P2S's 14.9 kg[1][4] | Superseded by the MK4S, which is the same machine plus a 360-degree turbine part-cooling fan, a high-flow CHT nozzle and firmware/profile work; Prusa sold a 99 USD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[5][2] |
| Market position: superseded? successor announced? | Current model, launched into the slot vacated by the discontinued X1-Carbon[3] | 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][5] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | Main nozzle 256 x 256 x 260 mm; auxiliary nozzle 235.5 x 256 x 256 mm; dual-nozzle printing 235.5 x 256 x 256 mm; total volume for two nozzles 256 x 256 x 260 mm. The sortable figure below is the main-nozzle volume[1] | 250 x 210 x 220 mm (manufacturer figure)[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 392 x 406 x 478 mm[1] | Not documented |
| Net weight (kg) | 16.25 kg net[1] | Not documented |
| Frame construction & material | Plastic and steel chassis; plastic, glass and metal outer frame[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/lid | Fully enclosed with a door sensor, active chamber heating to 65 C, and a G3 + H12 HEPA + granulated coconut-shell carbon filter stack with an external exhaust fan[1] | Open frame; the Original Prusa Enclosure is an optional add-on[2] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Active chamber heating, maximum 65 C (manufacturer figure)[1] | Not documented |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY - not stated in the spec sheet; Bambu groups the X2D with its enclosed CoreXY machines and publishes the same 20000 mm/s2 acceleration figure[1] | 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] |
| Stepper motors (frame size, step angle, brand if known) | Not documented | 400-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 documented | Trinamic TMC2130-LA silent stepper drivers on the xBuddy board[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 1000 mm/s max toolhead speed (manufacturer claim); no independent measurement found[1] | Not documented |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 max toolhead acceleration (manufacturer claim)[1] | Not documented |
| Max volumetric flow claimed (mm³/s) | 40 mm3/s, measured by Bambu on a 250 mm round single-wall model in Bambu ABS at 280 C[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Two direct-drive extruders: main extruder with hardened-steel gears driven by a Bambu high-precision permanent-magnet synchronous motor, auxiliary extruder with hardened-steel gears driven by a stepper motor[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 material | Not documented | 1:10 planetary gearbox[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Dual hardened-steel nozzles; 0.4 mm included, 0.2/0.4/0.6/0.8 mm supported; 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) | 300 C claimed max nozzle temperature[1] | 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][7] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 C max heatbed temperature[1] | 120 C max heatbed temperature[2] |
| Bed surface (material, texture, coating), single/double-sided | Flexible steel plate, Textured PEI included; Smooth PEI, Cool Plate SuperTack and Engineering Plate supported[1] | Magnetic heatbed with removable PEI spring-steel sheets; compatible with the MK3 sheets (smooth PEI, satin, textured PEI, PA nylon)[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Not documented | Load-cell sensor: fully automatic first-layer calibration with the nozzle as the probe, plus automatic mesh bed levelling over the print area[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Yes - run-out sensor, tangle sensor and door sensor; odometry with AMS[1] | Built-in Hall-effect filament sensor supporting automatic filament loading[2] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Part-cooling fan, hotend cooling fan, main control board fan, chamber heat-circulation fan, auxiliary part-cooling fan and external exhaust fan, all closed-loop controlled[1] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Motion controller dual-core Cortex-M4 plus single-core Cortex-M7; application processor quad-core ARM with a dedicated NPU (2 TOPS per the compare page)[1][8] | Custom 32-bit xBuddy board with STM32, designed and built in-house, with a separate extruder breakout board[2] |
| PSU (brand, wattage, rail voltage) | Not documented | 240 W Delta PSU with hardware power panic[2] |
| Total rated power draw | High-voltage version 1600 W at 220 V, low-voltage version 1100 W at 110 V; steady state 250 W printing PLA and 550 W printing PC at 25 C ambient[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[9] | 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[10][7] |
| 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 mobile app and PC app[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-drive | Dual-band Wi-Fi (802.11 a/b/g/n), built-in 8 GB eMMC and a USB port; Ethernet not available, no network kill switch, no 802.1X[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) | Two cameras: live-view 1920x1080 and a toolhead camera at 1600x1200[1] | Not documented |
| Materials Support | ||
| Officially supported filament list | Main hotend: PLA, PETG, ABS, ASA, TPU, support materials, PET, PA, PC, PVA and carbon/glass-fibre reinforced PLA, PETG, ABS, ASA, PA6, PAHT, PPA, PET. Auxiliary hotend drops PPA-CF/GF and excludes PLA Aero; PLA Silk, PETG-CF, ASA-CF, PA6-CF, TPU for AMS and PA/PET support material are flagged "print with caution" on the auxiliary nozzle[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) | Not documented | xBuddy hardware overcurrent protection disconnects heater and heatbed power when total current exceeds 15 A; firmware is open-source and auditable[2][10] |
| 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[11] | 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[12][7] |
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.
