| Property | Bambu Lab H2CCOREXY | Original Prusa MK4BEDSLINGER |
|---|---|---|
| Identity | ||
| Brand | Bambu Lab | Prusa Research |
| Class | COREXY | BEDSLINGER |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Bambu Lab H2C; spec sheet header "H2C Spec Sheet"[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 $2,199.00 on the Bambu Lab US store, Aug 2026, against a stated typical price of $2,399.00; the compare page shows $2,399[3] | Not documented |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Dual-nozzle top model in the H2 family, in the same 492x514x626 mm body as the H2D and H2S. Distinguishing figures: 32.5 kg (vs 31 kg H2D, 30 kg H2S); single-nozzle volume 305x320x325 mm (vs 325x320x325 mm on the H2D); BirdsEye camera fitted as standard rather than only on a Laser Edition; laser safety window listed as equipped with the Laser Edition[1][4][5][6] | Superseded by the MK4S, which is the same machine plus a 360-degree turbine part-cooling fan, a high-flow CHT nozzle and firmware/profile work; Prusa sold a 99 USD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[7][2] |
| Market position: superseded? successor announced? | Not documented | 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[8][7] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | Single-nozzle printing 305 x 320 x 325 mm; dual-nozzle printing 300 x 320 x 325 mm; total volume for two nozzles 330 x 320 x 325 mm. The sortable figure is the single-nozzle volume[1] | 250 x 210 x 220 mm (manufacturer figure)[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 492 x 514 x 626 mm[1] | Not documented |
| Net weight (kg) | 32.5 kg net[1] | Not documented |
| Frame construction & material | Aluminium and steel chassis with a plastic and glass 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, chamber exhaust and heat-circulation fans, G3 + H12 + granulated coconut-shell carbon filtration with VOC filtration rated Superior[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 named in the spec sheet; grouped by Bambu with the H2 enclosed CoreXY machines at 20000 mm/s2[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 | Dual direct-drive extruders, hardened-steel gears, Bambu high-precision permanent-magnet synchronous motors[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?) | Hardened-steel nozzles, 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) | 350 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][9] |
| 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 with Textured PEI included; Engineering Plate also 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 | ||

| Total rated power draw | 100-120 VAC / 200-240 VAC 50/60 Hz; 1800 W at 220 V, 1250 W at 110 V[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[10] | 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[11][9] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 5-inch 720x1280 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 | Wi-Fi; built-in 8 GB eMMC and a USB port. Ethernet not available[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) | Four cameras as standard: live view 1920x1080, nozzle camera 1920x1080, toolhead camera 1920x1080 and BirdsEye 3264x2448[1] | Not documented |
| Materials Support | ||
| Officially supported filament list | PLA, PETG, TPU, PVA, BVOH, ABS, ASA, PC, PA, PET, PPS, plus carbon/glass-fibre reinforced PLA, PETG, PA, PET, PC, ABS, ASA, PPA and PPS[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][11] |
| 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[12] | 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[13][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.
