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]Original Prusa MINI+ Semi-assembled 3D Printer[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]$508.33 on prusa3d.com, Aug 2026[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[6][1][2][3]Sold semi-assembled and, historically, as a kit; also offered in an Enclosure Bundle. Distinguish from the larger i3-family machines - the MINI+ is Bowden-fed with 2209 drivers, a 280 C nozzle ceiling and a 100 C bed, all lower than the MK3S+/MK4S. Note that Prusa's own MINI+ page carries an "Awards & Press Reviews" paragraph that is entirely about the MK3S, not the MINI+[4][7]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable153.36 x 77.76 x 165 mm[1]180 x 180 x 180 mm (manufacturer figure)[4]
Machine footprint (mm) & clearance needed (cable/spool overhang)260 x 268 x 451.5 mm[1]380 x 330 x 380 mm (X x Y x Z), stated without the spool holder and external PSU - the external PSU brick needs additional desk space[4]
Net weight (kg)Approximately 8.8 kg[1]4.5 kg without spool holder and external PSU[4]
Enclosure: open / enclosed; panel material; door/lidOpen-frame MSLA with a removable UV-blocking cover[1]Open frame; sold with an optional Enclosure bundle[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]Not documented
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documentedTrinamic 2209 silent stepper drivers, with sensorless homing on the X and Y axes[4]
Extruder
Type (direct drive / bowden) & design nameNot documentedBowden extruder with 3:1 gearing - the only current Prusa FFF machine that is not direct drive[4]
Gear ratio & drive gear materialNot documented3:1 extruder gearing[4]
Hotend & Nozzle
Max nozzle temp claimed AND firmware max temp limit (both values)Not documented280 C claimed max nozzle temperature - lower than the 290-300 C of the i3-family machines[4]
Heated Bed & Surface
Max bed temp claimed AND firmware limitNot documented100 C max heatbed temperature[4]
Bed surface (material, texture, coating), single/double-sidedNot documentedRemovable magnetic steel sheets in several surface finishes; heatbed with cold-corner compensation[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]SuperPINDA inductive probe with no temperature drift, driving automatic mesh bed levelling[4]
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Not documentedCustom 32-bit board of Prusa's Buddy family; the MINI/MINI+ is covered by the same Prusa-Firmware-Buddy source tree as the MK4, XL and CORE One. The exact board revision is not given on the product page[4][8]
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]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[8][9]
Connectivity, UI & Camera
Display: size, type, touch?4.0-inch capacitive touchscreen (control panel — not the masking LCD, see W1)[1]2.8-inch 65k-colour graphic screen with G-code preview[4]
On-device UI capabilities (model preview, per-object controls, etc.)Not documentedOn-device colour UI with G-code preview; remote print management through Prusa Connect[4]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveUSB and Wi-Fi[1]USB port, RJ-45 Ethernet, optional ESP Wi-Fi module (sold separately); compatible with Prusa Connect[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 documentedSemi-assembled: Prusa ships it in a small number of pre-built sections; also historically sold as a full kit[4]
Materials Support
Officially supported filament list405 nm photopolymer resin. No compatibility list published on this listing[1]PLA, PETG, ASA, ABS, PC, CPE, PVA/BVOH, PVB, HIPS, PP, Flex, nGen, Nylon, Woodfill and other filled materials (Prusa's own list; the 100 C bed and open frame are the practical limit for ABS/ASA)[4]
Safety
Thermal runaway protection (verify in firmware source if at all possible)Not documentedThree thermistors and fan RPM sensors are fitted, and the firmware is open-source and auditable (Prusa-Firmware-Buddy); Prusa does not describe the thermal-runaway implementation on the product page[4][8]
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[10][9]
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.
