| Property | Bambu Lab H2DCOREXY | FlashForge Guider 3 UltraINDUSTRIAL |
|---|---|---|
| Identity | ||
| Brand | Bambu Lab | FlashForge |
| Class | COREXY | INDUSTRIAL |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Bambu Lab H2D[1] | Flashforge Guider 3 Ultra; the FlashForge spec table gives the machine name as "Guider 3 Ultra"[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] | $2,399.00 against a $3,499.00 regular price on flashforge.com, but the listing checked is the refurbished SKU and is marked Sold out (Aug 2026)[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] | Top of the Guider 3 series. Build size depends on which head is used: 330 x 330 x 600 mm with one extruder, 300 x 330 x 600 mm with both. Siblings Guider 3 (300x250x340) and Guider 3 Plus (350x350x600) are both single-extruder. A refurbished SKU exists alongside the new machine, so check which one a price refers to[2][7][8] |
| Market position: superseded?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] | Not documented |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | Single-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] | 330 x 330 x 600 mm with a single extruder; 300 x 330 x 600 mm when both extruders are in use[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 492 x 514 x 626 mm[1] | 635 x 550 x 1070 mm; packaging 775 x 690 x 1235 mm[2] |
| Net weight (kg) | 31 kg net[1] | 70 kg net, 86 kg gross[2] |
| Frame construction & material | Aluminium, steel, plastic and glass chassis and shell[1] | Enclosed professional chassis; FlashForge describes a lightweight, stable structure for high-speed operation[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, and a G3 + H12 HEPA + granulated coconut-shell carbon filter stack[1] | Closed design with an air filter fitted[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; Bambu groups the H2 series with its enclosed CoreXY machines at 20000 mm/s2[1] | CoreXY with two extruders, per a third-party buyer's guide. FlashForge's own spec table does not state the kinematics[9][2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 1000 mm/s max toolhead speed (manufacturer claim); no independent measurement found[1] | 10-500 mm/s printing speed, 500 mm/s maximum travel speed (manufacturer figures)[2] |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 max toolhead acceleration (manufacturer claim)[1] | 20,000 mm/s2 maximum (manufacturer claim)[2] |
| 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 |
| Vibration Compensation / Input Shaping | ||
| Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary) | Not documented | Active vibration compensation, which FlashForge says was enhanced for this model. Implementation not named[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual direct-drive extruders with hardened-steel gears, driven by Bambu high-precision permanent-magnet synchronous motors[1] | Two extruders[2] |

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.
