Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)ELEGOO Mars 5. Elegoo's own product handle spells the configuration out: mars-5-4k-6-6inch-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 documentedNot published on the listings checked (Aug 2026)[4][5]
Street price (USD; dated snapshot per entry)$179.00 on us.elegoo.com against a $225.00 compare-at price (20% off), in stock, checked Aug 2026. The live product feed shows the same $179.00[2][3]$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)Sold beside the Mars 5 Ultra, which is a materially different machine: 7-inch 9K masking LCD vs 6.6-inch 4K, 18 um vs 35 um pixels, 150 vs 70 mm/h, a 4.0-inch capacitive control screen vs 3.5-inch resistive, and Wi-Fi (the plain Mars 5 is USB only). Elegoo lists ten further Mars 5 / Mars 5 Ultra bundle SKUs pairing the printers with Mercury wash-and-cure stations at $302-$432; those are not printer prices[1][6][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Market position: superseded?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 documentedDiscontinued; QIDI's current line is the Q, Plus and Max series[5][7]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable143.43 x 89.6 x 150 mm[1]330 x 250 x 320 mm advertised[4][5]
Machine footprint (mm) & clearance needed (cable/spool overhang)230 x 230 x 433.5 mm[1]710 x 510 x 670 mm[5]
Net weight (kg)Approximately 6.6 kg[1]33 kg net[5]
Frame construction & materialMetal frame with adjustable foot pads[1]Fully assembled enclosed metal-frame machine[4]
Enclosure: open / enclosed; panel material; door/lidOpen-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 — UV LCD masked stereolithography. Single Z axis, build plate lifting straight out of the vat (no tilt-release on this model, unlike the Mars 5 Ultra)[1][6]Dual independent extruders in an enclosed Cartesian gantry[4][5]
Speed & Acceleration
Max print speed (claimed, mm/s)Not documented30-150 mm/s print speed range (manufacturer figure — a working range, not a peak marketing number)[5]
Extruder
Type (direct drive / bowden) & design nameNot documentedDirect-drive, two extruders. MK10-style nozzle[4][5]
Hotend & Nozzle
Max nozzle temp claimed AND firmware max temp limit (both values)Not documented350 °C on the high-temperature extruder assembly[4][5]
Stock nozzle size & sizes included in boxNot documented0.4 mm nozzle diameter[5]
Heated Bed & Surface
Bed surface (material, texture, coating), single/double-sidedLaser-engraved build plate with a quick-release design[1]Not documented
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Automatic levelling, one click. An intelligent mechanical sensor detects resin residue to prevent LCD damage[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 drawNot documented700 W rated[5]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Not named by Elegoo. Supported slicers are Voxeldance Tango and CHITUBOX; STL and OBJ accepted[1]Not documented
Connectivity, UI & Camera
Display: size, type, touch?3.5-inch resistive touchscreen (control panel — not the masking LCD, see W1)[1]Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveUSB only — no Wi-Fi on this model[1]Wi-Fi, LAN, USB flash drive[4][5]
Materials Support
Officially supported filament list405 nm photopolymer resin. Elegoo does not publish a resin compatibility list on this listing[1]Carbon fibre, nylon, PETG, TPU, PC, ABS, PLA[5]
Safety
Firmware safety limits (max temp cutoffs — exact values)Intelligent overheating protection stops printing above 80 °C[1]Not documented
Resin & MSLA
Masking LCD6.6-inch 4K monochrome masking LCD, 4098 x 2560 px, XY pixel pitch 35 x 35 um (manufacturer specification)[1][3]Not documented
Light sourceCOB LED at 405 nm. Elegoo does not publish an LED count or collimating optics for this model[1]Not documented
Vertical print speedmm/h70 mm/h maximum (manufacturer claim). Elegoo does not state the layer height or resin type the figure assumes[1]Not documented
Release filmPFA film with a non-stick surface. No rated life published[1]Not documented
Resin vat & feedingReplaceable resin tank with two pouring openings and screw caps. An intelligent mechanical sensor detects resin residue in the vat. Capacity not published; no auto-refill[1]Not documented
Fume extractionNone fitted. Elegoo states compatibility with the separately sold MARS MATE air purifier for odour reduction[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.
