| Class | RESIN | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Mars 5 Ultra. Elegoo's product handle is mars-5-ultra-9k-7inch-monochrome-lcd-resin-3d-printer[1][2][3] | QIDI Plus4, sold as "Plus4 3D Printer". QIDI's own wiki files it under X-Plus4[4][5] |
| Release date (announcement and actual shipping) | Not documented | Announced September 2024; QIDI ran launch promotional pricing in the week of 20-27 September 2024 (secondary reporting, not a QIDI press release)[6] |
| Street price (USD; dated snapshot per entry) | $269.00 in Elegoo's live US product feed, in stock, checked Aug 2026. The Mars 5 Series collection page rendered $259.00 against a $338.00 compare-at price on the same day, so the two Elegoo surfaces disagree by $10[3][2] | $649.00 on us.qidi3d.com for the Plus4 + 1 filament variant against a $799.00 compare-at price; $699.00 on qidi3d.com against $799.00. Checked Aug 2026[4][5] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Not a trim of the Mars 5 — a different imaging stack and a different release mechanism: 7-inch 9K LCD and 18 um pixels vs 6.6-inch 4K and 35 um, 150 vs 70 mm/h, tilt-release vs straight lift, an AI camera, and Wi-Fi added. Seven bundle SKUs pair it with Mercury Plus V2.0/V3.0 or Mercury XS at $363-$432[7][1][2][3] | Two purchasable variants: Plus4 + Filament x1 at $649 and Plus4 Combo + Filament x1 at $799 (Combo adds the QIDI Box multi-material unit). Distinct from the older X-Plus 3 (280x280x270, 350 °C) and from the newer Plus5 (320x320x300)[5][4] |
| Market position: superseded? successor announced? | Not documented | Superseded at the top of the large-format line by the Plus5, launched 5 August 2026 with 18% more build volume; Plus4 still listed and in stock Aug 2026[8][9] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 153.36 x 77.76 x 165 mm[1] | 305 x 305 x 280 mm advertised. No independently measured usable envelope found[4][6] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 260 x 268 x 451.5 mm[1] | 505 x 487 x 550 mm[6] |
| Net weight (kg) | Approximately 8.8 kg[1] | 32 kg gross (3DJake). QIDI does not publish a net weight on the product page[6] |
| Frame construction & material | Not documented | Enclosed CoreXY chassis with double-layer chamber insulation; QIDI does not publish a frame material breakdown[4] |
| Enclosure: open / enclosed; panel material; door/lid | Open-frame MSLA with a removable UV-blocking cover[1] | Fully enclosed, double-layer insulated chamber with second-generation active heating to 65 °C[4][6] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | 65 °C, actively heated by a 400 W heater which QIDI says reaches setpoint in about 8 minutes (manufacturer claim)[4][6] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | MSLA with tilt-release: the resin tank tilts after each layer to peel the part rather than pulling straight up. Single Z axis[1] | CoreXY[6] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Not documented | Dual independent Z motors on 10 mm linear shafts and screws[4] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | Not documented | 600 mm/s (manufacturer claim, tool-head maximum)[6] |
| Max acceleration (claimed, mm/s²) | Not documented | <=20,000 mm/s2 (manufacturer claim)[6] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Not documented | Direct drive with hardened steel dual gears, 1.75 mm filament[4][6] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | Second-generation 80 W bimetal hotend with a multi-metal composite hardened-tip nozzle; 0.4 mm standard, 0.2/0.5/0.8 mm optional[4][6] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | Not documented | <=370 °C claimed. No firmware max_temp verified for this model[4][6] |
| Heater cartridge power (W) | Not documented | 80 W hotend heater (manufacturer figure)[4] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | Not documented | Conflicting manufacturer figures: QIDI's own Plus4 page states a 100 °C bed temperature, 3DJake's spec table states <=120 °C. Not resolved; the lower vendor-published figure is used as the sortable value[4][6] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | 6 mm aluminium-substrate heated bed with a double-sided textured PEI plate[4][6] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Automatic levelling, one click, via an intelligent mechanical sensor. One-Click Self-Check routine. Alarms for resin shortage, residue detection and levelling failure[1] | Full-auto calibration; QIDI markets "hands-free automatic" levelling and does not name the probe technology on the product page[4][6] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Not documented | Filament run-out sensor, plus a filament cutter and filament tangle detection (tangle mechanism not described)[6] |

| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.0-inch capacitive touchscreen (control panel — not the masking LCD, see W1)[1] | 5-inch touchscreen, 800 x 480[4][6] |

| Cloud service & phone app; LAN-only mode possible? | Not documented | Mobile and computer control, remote cloud or LAN-only operation[4] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | AI camera fitted; Elegoo does not publish its resolution for this model[1] | Built-in low-frame-rate camera, up to 1080p, timelapse supported[4][6] |
| Camera features: live monitor, timelapse, AI failure detection (spaghetti detection) — how real is it? | AI camera detects empty build plates and print errors[1] | Not documented |

| Materials Support | ||
| Officially supported filament list | 405 nm photopolymer resin. No compatibility list published on this listing[1] | PLA, ABS, ASA, PETG, TPU, PA, PC, PA-CF/GF, PET-CF/GF, PPA-CF/GF, PPS-CF and other CF/GF-filled polymers[4][6] |

| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | Not documented | 1-year coverage, 14-day no-reason return, 30-day price protection[4] |
| Resin & MSLA | ||
| Masking LCD | 7-inch 9K monochrome masking LCD, 8520 x 4320 px, XY pixel pitch 18 x 18 um (manufacturer specification)[1][3] | Not documented |
| Light source | 25-LED COB light source emitting a 405 nm UV beam (manufacturer specification)[1] | Not documented |
| Light uniformity & intensity | 92% light uniformity claimed by Elegoo. No intensity figure published, and no independent measurement[1] | Not documented |
| Vertical print speedmm/h | 150 mm/h maximum, which Elegoo attributes to the tilt-release mechanism (manufacturer claim). Elegoo also offers switchable slow and fast print modes but does not state the layer height the figure assumes[1] | Not documented |
| Layer exposure times | 1.5-3 s layer cure time (manufacturer figure; layer height not stated). Sortable value is the midpoint[1] | Not documented |
| LCD life & replaceability | Masking LCD protected by a scratch-resistant tempered 9H glass cover that also guards against resin leakage. Elegoo publishes no rated screen life in hours and does not state whether the user can replace the LCD[1] | Not documented |
| Resin vat & feeding | Resin tank supplied with the machine; resin-shortage and residue-detection alarms fitted. Capacity not published; no auto-refill[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.
