ClassCOREXYBEDSLINGER
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Bambu Lab H2D[1]Original Prusa i3 MK3S+. The only version still listed in Aug 2026 is the "Original Prusa i3 MK3S+ 10th Anniversary Edition"[2]
Street price (USD; dated snapshot per entry)From $1,549.00 on the Bambu Lab US store, Aug 2026, against a stated typical price of $1,749.00; the product page shows $1,749.00 (typical $1,999.00) with a combo variant selected[3][4]$1,199.00 assembled, $899.00 as a kit, for the 10th Anniversary Edition on prusa3d.com, Aug 2026. This is above the price the standard MK3S+ sold at, so do not read it as the MK3S+ street price[2]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Six SKUs on one product page including H2D, H2D AMS Combo and H2D Laser Full Combo. The Laser Edition adds laser safety windows and the air-assist pump; a plain H2D can be upgraded with a Laser Upgrade Kit. The BirdsEye camera is only fitted on the Laser Edition. Siblings in the same family are the H2S (single nozzle, 340x320x340 mm, 30 kg) and H2C (dual nozzle, 305x320x325 mm single-nozzle volume, 32.5 kg, four cameras as standard) - all three share the 492x514x626 mm body, so body dimensions alone will not tell them apart[1][5][6]Only the 10th Anniversary Edition remains on sale; the standard MK3S+ is gone from Prusa's printer listing. Two official upgrade paths change the machine substantially and are frequently confused with it: MK3.5 (xBuddy board and new LCD, keeps the MK3 extruder) and MK3.9 (adds the Nextruder). A caution on Prusa's own pages: the "Awards & Press Reviews" paragraph about the MK3S is reproduced verbatim on the MINI+ product page, so award text found on a Prusa page does not necessarily belong to the printer on that page[2][7][8][9]
Market position: superseded? successor announced?Current model; the H2C sits above it in the same body at $2,199 and the H2S below it at $1,199[3]Superseded by the MK4/MK4S line. Prusa cut MK3S+ prices at the MK4 launch in March 2023 and said it would keep selling the MK3S+ at a lower price and hold spare parts in stock[8][9]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usableSingle-nozzle printing 325 x 320 x 325 mm; dual-nozzle printing 300 x 320 x 320 mm; total volume across the two nozzles 350 x 320 x 320 mm. The sortable figure is the single-nozzle volume[1]25 x 21 x 21 cm = 250 x 210 x 210 mm (manufacturer figure)[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)492 x 514 x 626 mm[1]500 x 550 x 400 mm (X x Y x Z), without the spool holder[2]
Net weight (kg)31 kg net[1]7 kg (without spool)[2]
Frame construction & materialAluminium, steel, plastic and glass chassis and shell[1]Cut aluminium frame - Prusa's MK4 announcement contrasts "the cut aluminum frame we used so far" with the MK4's new die-cast frame[8]
Enclosure: open / enclosed; panel material; door/lidFully enclosed with a door sensor; active chamber heating to 65 C, chamber exhaust and heat-circulation fans, and a G3 + H12 HEPA + granulated coconut-shell carbon filter stack[1]Open frame; the Original Prusa Enclosure is an optional separate product[8]
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; Bambu groups the H2 series with its enclosed CoreXY machines at 20000 mm/s2[1]Cartesian i3 bed-slinger. Prusa's MK4 announcement notes the MK3S+ Y-axis profiles and heatbed were among the few parts carried into the MK4[8]
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documentedTrinamic 2130 drivers at 256 microstepping on the EINSY RAMBo 8-bit board, co-developed with UltiMachine; sensorless homing on X and Y[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 travel speedNot documented"200+ mm/s" max travel speed (manufacturer figure, no measurement basis given)[2]
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 with the standard-flow hotend, 65 mm3/s with the optional high-flow hotend; both 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 nameDual direct-drive extruders with hardened-steel gears, driven by Bambu high-precision permanent-magnet synchronous motors[1]Direct drive with Bondtech gears and an E3D V6 hotend[2]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)All-metal hotend with hardened-steel nozzle, 0.4 mm included, 0.2/0.4/0.6/0.8 mm supported; an optional high-flow hotend is offered[1]Not documented
Max nozzle temp claimed AND firmware max temp limit (both values)350 C claimed max nozzle temperature[1]300 C claimed max nozzle temperature[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit120 C max heatbed temperature[1]120 C max heatbed temperature[2]
Bed surface (material, texture, coating), single/double-sidedTextured PEI plate and Smooth PEI plate supported[1]Removable magnetic spring-steel sheets in several finishes; heatbed with cold-corner compensation[2]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Not documentedSuperPINDA inductive probe (Prusa's temperature-drift-free replacement for the original PINDA), driving automatic mesh bed levelling and a self-test routine[2]
Filament Handling & Detection
Filament runout sensor (type, location)Yes - run-out sensor, tangle sensor and door sensor; odometry with AMS[1]IR filament sensor built in, supporting filament auto-loading; the print pauses when filament runs out[2]

Total rated power draw100-120 VAC / 200-240 VAC 50/60 Hz; 2200 W at 220 V, 1320 W at 110 V. The US store page states the H2D it sells is the 100-120 V version[1]Power consumption 80 W on PLA settings, 120 W on ABS settings[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[10]prusa3d/Prusa-Firmware on GitHub, GPL-3.0, whose README states it is "proudly based on Marlin 1.0.x" and covers the MK3S/MK3/MK2.5S/MK2.5 line; last pushed August 2025. Updated over USB from a PC[11]

Safety
Thermal runaway protection (verify in firmware source if at all possible)Not documentedPrusa shipped Thermal Model protection to the MK3 line as a firmware update shortly before the MK4 launch; the firmware is open-source and auditable[8][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][14]

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.
