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]Prusa CORE One L+[4]
Release date (announcement and actual shipping)Not documentedThe CORE One L+ refresh was announced on 13 August 2026 and went on sale immediately, with the first assembled units shipping at once; it adds GT1.5 belts and an integrated nozzle wiper to the CORE One L[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]$1,850.93 on prusa3d.com, Aug 2026; $1,925.00 with the Advanced Filtration bundle. Prusa's own comparison text on the CORE One+ page quotes "from $1,799", which does not match the live e-shop price[6][7]
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[8][1][2][3]Larger sibling of the CORE One+ (Gen 2): 300 x 300 x 330 mm against 250 x 220 x 270 mm, 60 C chamber against 55 C, 21.9 kg against 22.5 kg (the L is the lighter of the two despite being larger). A CORE One L to CORE One L+ upgrade kit exists, so "CORE One L" and "CORE One L+" are different revisions. A Critical Infrastructure Edition is also listed[4][7][6]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable153.36 x 77.76 x 165 mm[1]300 x 300 x 330 mm, which Prusa states as 29.7 litres[4]
Machine footprint (mm) & clearance needed (cable/spool overhang)260 x 268 x 451.5 mm[1]469 x 521 x 635 mm[4]
Net weight (kg)Approximately 8.8 kg[1]21.9 kg (48.3 lb)[4]
Enclosure: open / enclosed; panel material; door/lidOpen-frame MSLA with a removable UV-blocking cover[1]Fully enclosed with a chamber door-open sensor and an active convection heated chamber up to 60 C; advanced filtration is an optional add-on[4]
Passive chamber temperature reached (if enclosed; measured values preferred)Not documentedActive convection chamber heating, maximum 60 C (manufacturer figure)[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 - stated in Prusa's CORE One+ comparison table[7]
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documentedTrinamic drivers on the custom xBuddy mainboard (Prusa's CORE One L+ specification says "custom 32-bit xBuddy mainboard with STM32 processor & Trinamic drivers"; it does not give the driver part number)[4]
Vibration Compensation / Input Shaping
Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary)Not documentedInput Shaper and Phase Stepping with an integrated accelerometer[4]
Extruder
Type (direct drive / bowden) & design nameNot documentedNextruder direct drive with a 10:1 planetary gear system; all-metal hotend with an aluminium heatsink and a tool-free quick-swap nozzle system[4]
Gear ratio & drive gear materialNot documented10:1 planetary gearbox[4]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Not documentedTool-free quick-swap nozzle system; Prusa brass high-flow CHT 0.4 mm pre-mounted plus an abrasive-resistant 0.4 mm nozzle in the box[4]
Max nozzle temp claimed AND firmware max temp limit (both values)Not documented290 C claimed max nozzle temperature. The optional HT hotend that raises this to 400 C was announced for September 2026 availability, so it is not a shipping specification as of Aug 2026[4][5]
Heated Bed & Surface
Max bed temp claimed AND firmware limitNot documented120 C max heatbed temperature[4]
Bed surface (material, texture, coating), single/double-sidedNot documentedMagnetic heatbed with removable dual-sided PEI spring-steel sheets; a satin powder-coated sheet is supplied[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]High-precision load-cell sensor - fully automatic first-layer calibration and mesh bed levelling restricted to the print area[4]
Filament Handling & Detection
Filament runout sensor (type, location)Not documentedTwo filament sensors, plus a chamber door-open sensor and five Semitec thermistors[4]
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Not documentedCustom 32-bit xBuddy mainboard with an STM32 processor[4]
Input voltage (110/220 V, switch or auto)100-240 V, 50/60 Hz, 24 V 3 A[1]Not documented
Total rated power drawNot documentedStandby 16 W, preheating about 630 W, average printing about 90 W on PLA and about 215 W on ASA (manufacturer figures)[4]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Not named by Elegoo. Supported slicer is CHITUBOX[1]Open-source Prusa Buddy firmware. The source tree (prusa3d/Prusa-Firmware-Buddy on GitHub) explicitly covers the Original Prusa MINI/MINI+, MK4, XL and CORE One and was last pushed to in August 2026. Updates are applied from a USB drive, through Prusa Connect or through the Prusa mobile app[9][10]
Connectivity, UI & Camera
Display: size, type, touch?4.0-inch capacitive touchscreen (control panel — not the masking LCD, see W1)[1]3.5-inch 65k-colour touch screen (CORE One family)[7]
On-device UI capabilities (model preview, per-object controls, etc.)Not documentedOn-device touch UI with Prusa Connect and Prusa mobile app remote control[7]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveUSB and Wi-Fi[1]Ethernet, NFC receiver and Wi-Fi through a physically removable module, which Prusa offers for high-security offline installations[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

Firmware safety limits (max temp cutoffs — exact values)Overheating protection activates above 80 °C[1]Not documented
Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)Not documented2-year warranty for consumers in the EU, Liechtenstein, Switzerland, Norway and Iceland; 1 year for EU enterprises and 1 year for the rest of the world, which includes the United States. A printer bought from a reseller or privately carries 1 year from the original delivery date and is handled by the reseller. Prusa advertises 24/7 chat and e-mail support in seven languages[12][10]
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.
