|---|---|---|
| Identity | ||
| Brand | Bambu Lab | ELEGOO |
| Class | COREXY | RESIN |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Bambu Lab H2D[1] | Elegoo Saturn 4 Ultra 16K. Elegoo's product handle is saturn-4-ultra-16k-10inch-monochrome-lcd-resin-3d-printer. 3DJake item number ELG-50.101.038300[2][3] |
| 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[4][5] | $649.99 in us.elegoo.com's live Shopify product JSON, in stock, with compare_at_price also $649.99 — no discount active at the time of checking (Aug 2026)[3] |
| 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][6][7] | Distinct from the earlier Saturn 4 Ultra (12K); the 16K carries a 15120 x 6230 masking LCD with 14 x 19 um pixels. Elegoo also sells it bundled with a Mercury Plus V2.0 wash/cure station and as a pre-owned SKU, neither of which is the printer-only price[2][3] |
| Market position: superseded?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[4] | 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] | 211.68 x 118.37 x 220 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 492 x 514 x 626 mm[1] | 327.4 x 329.2 x 548 mm[2] |
| Net weight (kg) | 31 kg net[1] | Not documented |
| Frame construction & material | Aluminium, steel, plastic and glass chassis and shell[1] | Metal housing with a flip-up cover and a drip guard[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] | Flip-up lid (Elegoo's own naming) over an open frame; UV-blocking cover[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] | MSLA with tilt-release: the vat tilts to peel each layer rather than pulling straight up. Elegoo claims the mechanism cuts curing time by 25%. Single Z axis, Z precision 0.02 mm[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 name | Dual direct-drive extruders with hardened-steel gears, driven by Bambu high-precision permanent-magnet synchronous motors[1] | Not documented |
| 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] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 C max heatbed temperature[1] | Not documented |

| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Not documented | Automatic levelling, plus intelligent mechanical sensor alarms[2] |
| Filament Handling & Detection | ||

| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Part-cooling fan, auxiliary part-cooling fan, chamber heat-circulation fan, hotend cooling fan, main control board fan and chamber exhaust fan, all closed-loop controlled[1] | Not documented |

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.
