Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Bambu Lab H2D[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)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[5][6]$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)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][7][8]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][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Market position: superseded?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[5]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 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]250 x 220 x 270 mm (manufacturer figure)[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)492 x 514 x 626 mm[1]415 x 444 x 555 mm (X x Y x Z)[2]
Net weight (kg)31 kg net[1]22.5 kg[2]
Frame construction & materialAluminium, steel, plastic and glass chassis and shell[1]All-steel exoskeleton (Prusa's own comparison wording, against "aluminium extrusions and frame" for the MK4S)[10]
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]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][10]
Passive chamber temperature reached (if enclosed; measured values preferred)Active chamber heating, maximum 65 C (manufacturer figure)[1]Active chamber heating, maximum 55 C (manufacturer figure)[2]
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]CoreXY - stated as such in Prusa's own comparison table against the Cartesian MK4S[2]
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)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 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]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 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]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)350 C claimed max nozzle temperature[1]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

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][10]

Safety
Thermal runaway protection (verify in firmware source if at all possible)Not documentedThe xBuddy platform carries hardware overcurrent protection that cuts heater and heatbed power above 15 A, and the firmware is open-source and auditable[13][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][10]

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.
