| Identity | ||
| Brand | ELEGOO | QIDI |
| Class | RESIN | IDEX |
| 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 Tech i-Fast, also written iFast and "I-Fast"[4][5] |
| Release date (announcement and actual shipping) | Not documented | Not published on the listings checked (Aug 2026)[4][5] |
| 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] | $1,899.00 at Top 3D Shop, listed as discontinued with a 5-10 business-day lead time, checked Aug 2026. 3DJake no longer sells it[5][4] |
| 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[6][1][2][3] | Ships with two interchangeable dual-extruder assemblies — a standard dual head and a high-temperature dual head rated to 350 °C. Specifications quoted for one head do not apply to the other. Not to be confused with QIDI's i-Mate or the X-CF Pro[5][4] |
| Market position: superseded? successor announced? | Not documented | Discontinued; QIDI's current line is the Q, Plus and Max series[5][7] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 153.36 x 77.76 x 165 mm[1] | 330 x 250 x 320 mm advertised[4][5] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 260 x 268 x 451.5 mm[1] | 710 x 510 x 670 mm[5] |
| Net weight (kg) | Approximately 8.8 kg[1] | 33 kg net[5] |
| Frame construction & material | Not documented | Fully assembled enclosed metal-frame machine[4] |
| Enclosure: open / enclosed; panel material; door/lid | Open-frame MSLA with a removable UV-blocking cover[1] | Fully enclosed with a heated chamber[4][5] |
| 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] | Dual independent extruders in an enclosed Cartesian gantry[4][5] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | Not documented | 30-150 mm/s print speed range (manufacturer figure — a working range, not a peak marketing number)[5] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Not documented | Direct-drive, two extruders. MK10-style nozzle[4][5] |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | Not documented | 350 °C on the high-temperature extruder assembly[4][5] |
| Stock nozzle size & sizes included in box | Not documented | 0.4 mm nozzle diameter[5] |
| 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] | Not documented |
| Electronics & Power | ||
| Input voltage (110/220 V, switch or auto) | 100-240 V, 50/60 Hz, 24 V 3 A[1] | 110-220 V[5] |
| Total rated power draw | Not documented | 700 W rated[5] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Not named by Elegoo. Supported slicer is CHITUBOX[1] | Not documented |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.0-inch capacitive touchscreen (control panel — not the masking LCD, see W1)[1] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | USB and Wi-Fi[1] | Wi-Fi, LAN, USB flash drive[4][5] |
| 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] | Not documented |
| 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] | Carbon fibre, nylon, PETG, TPU, PC, ABS, PLA[5] |
| Safety | ||
| Firmware safety limits (max temp cutoffs — exact values) | Overheating protection activates above 80 °C[1] | Not documented |
| 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.
