ELEGOO Mars 5 Ultra vs Positron V3.2 — documented properties and sources

Identity

ClassRESINCOREXY
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]LDO Positron v3.2 3D Printer Kit, revision v3.2 Rev A[4]
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]Not documented
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[5][1][2][3]The defining trait is the inverted geometry: the print head is below the bed and the machine prints upside down. Sold as a self-assembly kit; the complete printed-parts set is a separate purchase. A hard storage case is included[4]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable153.36 x 77.76 x 165 mm[1]180 x 180 x 165 mm[4]
Machine footprint (mm) & clearance needed (cable/spool overhang)260 x 268 x 451.5 mm[1]200 x 200 x 70 mm folded, 200 x 200 x 270 mm unfolded[4]
Net weight (kg)Approximately 8.8 kg[1]3 kg net; 5.5 kg with the hard case[4]
Frame construction & materialNot documentedFolding frame designed to fit in a filament box; supplied with a black hard case[4]
Enclosure: open / enclosed; panel material; door/lidOpen-frame MSLA with a removable UV-blocking cover[1]Open frame[4]
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, inverted — the machine prints upside down[4]
Speed & Acceleration
Max print speed (claimed, mm/s)Not documented250 mm/s maximum print speed (manufacturer claim)[4]
Max acceleration (claimed, mm/s²)Not documented8,000 mm/s2 (manufacturer claim)[4]
Extruder
Type (direct drive / bowden) & design nameNot documentedBowden-style, single extrusion[4]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Not documentedPS plated-copper nozzle, 0.4 mm[4]
Max nozzle temp claimed AND firmware max temp limit (both values)Not documented260 °C maximum (manufacturer claim)[4]
Stock nozzle material (brass / hardened steel / plated copper / composite tip)Not documentedPlated copper[4]
Heated Bed & Surface
Max bed temp claimed AND firmware limitNot documented85 °C maximum bed temperature — the lowest in this group, and the reason the material list stops at PETG[4]
Bed surface (material, texture, coating), single/double-sidedNot documentedHeated removable ITO glass bed[4]
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
Mainboard model & MCU (exact chip markings if teardowns exist)Not documentedLDO Positron mainboard[4]
PSU (brand, wattage, rail voltage)Not documentedDC 24 V, 200 W[4]
Input voltage (110/220 V, switch or auto)100-240 V, 50/60 Hz, 24 V 3 A[1]Not documented
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Not named by Elegoo. Supported slicer is CHITUBOX[1]Klipper[4]
Connectivity, UI & Camera
Display: size, type, touch?4.0-inch capacitive touchscreen (control panel — not the masking LCD, see W1)[1]3.5-inch LCD touchscreen[4]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveUSB and Wi-Fi[1]Wi-Fi, USB, Ethernet[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]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
Calibration Routines & QoL
Assembly level & time from unbox to first printNot documentedSelf-assembly kit, manufactured in China[4]
Materials Support
Officially supported filament list405 nm photopolymer resin. No compatibility list published on this listing[1]PLA and PETG only, per the manufacturer[4]
Safety
Firmware safety limits (max temp cutoffs — exact values)Overheating protection activates above 80 °C[1]Not documented
Resin & MSLA
Masking LCD7-inch 9K monochrome masking LCD, 8520 x 4320 px, XY pixel pitch 18 x 18 um (manufacturer specification)[1][3]Not documented
Light source25-LED COB light source emitting a 405 nm UV beam (manufacturer specification)[1]Not documented
Light uniformity & intensity92% light uniformity claimed by Elegoo. No intensity figure published, and no independent measurement[1]Not documented
Vertical print speedmm/h150 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 times1.5-3 s layer cure time (manufacturer figure; layer height not stated). Sortable value is the midpoint[1]Not documented
LCD life & replaceabilityMasking 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 & feedingResin 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.
