| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Bambu Lab X2D; spec PDF header "X2D Spec"[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 $649.00 on the Bambu Lab US store, Aug 2026; the compare page shows the same $649 figure[4] | $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) | Dual-nozzle machine: a main hotend with a permanent-magnet synchronous extruder motor and an auxiliary hotend with a plain stepper motor, so the two nozzles are not equivalent. Bambu publishes four different build volumes depending on which nozzle is used, and a shorter list of materials for the auxiliary nozzle. Physical dimensions (392x406x478 mm) are shared with the P2S but the X2D is 16.25 kg against the P2S's 14.9 kg[1][5] | 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| Market position: superseded?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, launched into the slot vacated by the discontinued X1-Carbon[4] | Not documented |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | Main nozzle 256 x 256 x 260 mm; auxiliary nozzle 235.5 x 256 x 256 mm; dual-nozzle printing 235.5 x 256 x 256 mm; total volume for two nozzles 256 x 256 x 260 mm. The sortable figure below is the main-nozzle volume[1] | 211.68 x 118.37 x 220 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 392 x 406 x 478 mm[1] | 327.4 x 329.2 x 548 mm[2] |
| Net weight (kg) | 16.25 kg net[1] | Not documented |
| Frame construction & material | Plastic and steel chassis; plastic, glass and metal outer frame[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, and a G3 + H12 HEPA + granulated coconut-shell carbon filter stack with an external exhaust fan[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 stated in the spec sheet; Bambu groups the X2D with its enclosed CoreXY machines and publishes the same 20000 mm/s2 acceleration figure[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, 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 | Two direct-drive extruders: main extruder with hardened-steel gears driven by a Bambu high-precision permanent-magnet synchronous motor, auxiliary extruder with hardened-steel gears driven by a stepper motor[1] | Not documented |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Dual hardened-steel nozzles; 0.4 mm included, 0.2/0.4/0.6/0.8 mm supported; built-in filament cutter[1] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 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 | ||
| Filament runout sensor (type, location) | Yes - run-out sensor, tangle sensor and door sensor; odometry with AMS[1] | Not documented |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Part-cooling fan, hotend cooling fan, main control board fan, chamber heat-circulation fan, auxiliary part-cooling fan and external exhaust fan, all closed-loop controlled[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[7] | Elegoo EL3D-4.0 system. Slicer is CHITUBOX[2] |

Auxiliary hotend drops PPA-CF/GF and excludes PLA Aero; PLA Silk, PETG-CF, ASA-CF, PA6-CF, TPU for AMS and PA/PET support material are flagged "print with caution" on the auxiliary nozzle[1] | 405 nm photopolymer resin; the heated tank is aimed at high-viscosity and high-speed resins. No closed compatibility list published[2] |
| 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.

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.
