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]Original Prusa MK4[4]
Release date (announcement and actual shipping)Not documentedAnnounced 29 March 2023 with assembled printers shipping immediately from stock; kits opened for ordering about two weeks later[4]
Launch MSRP (USD)Not documented1099 USD assembled, 799 USD as a kit, VAT included, at launch[4]
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]Not documented
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SKUs pairing the printers with Mercury wash-and-cure stations at $302-$432; those are not printer prices[1][5][2][3]Superseded by the MK4S, which is the same machine plus a 360-degree turbine part-cooling fan, a high-flow CHT nozzle and firmware/profile work; Prusa sold a 99 USD MK4-to-MK4S upgrade kit and automatically converted unshipped MK4 orders to the S version. The MK3.5 and MK3.9 upgrades convert an MK3S+ to part of the MK4 electronics stack but are not an MK4[6][4]
Market position: superseded? successor announced?Not documentedDiscontinued. No MK4 appears in Prusa's Aug 2026 3D-printer listing, and the MK4 product-page slugs redirect to the MK4S page, so no live first-party price could be recorded[7][6]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable143.43 x 89.6 x 150 mm[1]250 x 210 x 220 mm (manufacturer figure)[4]
Machine footprint (mm) & clearance needed (cable/spool overhang)230 x 230 x 433.5 mm[1]Not documented
Net weight (kg)Approximately 6.6 kg[1]Not documented
Frame construction & materialMetal frame with adjustable foot pads[1]Die-cast aluminium frame - Prusa replaced the MK3S+'s cut-aluminium frame for the MK4, keeping only the Y-axis profiles, some bearings, the heatbed and the power supply[4]
Enclosure: open / enclosed; panel material; door/lidOpen-frame MSLA with a removable UV-blocking cover[1]Open frame; the Original Prusa Enclosure is an optional add-on[4]
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][5]Cartesian bed-slinger of the Prusa i3 family - Prusa's MK4 announcement records that the MK3S+ Y-axis profiles and heatbed were carried over[4]
Stepper motors (frame size, step angle, brand if known)Not documented400-step (0.9 degree) stepper motors, stated by Prusa to prevent vertical fine artefacts[4]
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documentedTrinamic TMC2130-LA silent stepper drivers on the xBuddy board[4]
Extruder
Type (direct drive / bowden) & design nameNot documentedNextruder direct drive with a planetary gear system, 1:10 gearbox ratio; aluminium heatsink, all-metal hotend, no PTFE tube in the filament path[4]
Gear ratio & drive gear materialNot documented1:10 planetary gearbox[4]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Not documentedQuick-swap nozzle system, 0.4 mm default, other diameters supported[4]
Max nozzle temp claimed AND firmware max temp limit (both values)Not documented300 C claimed max hotend temperature in Prusa's MK4 announcement table - note the MK4S product page publishes 290 C for the same hotend family[4][8]
Heated Bed & Surface
Max bed temp claimed AND firmware limitNot documented120 C max heatbed temperature[4]
Bed surface (material, texture, coating), single/double-sidedLaser-engraved build plate with a quick-release design[1]Magnetic heatbed with removable PEI spring-steel sheets; compatible with the MK3 sheets (smooth PEI, satin, textured PEI, PA nylon)[4]
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]Load-cell sensor: fully automatic first-layer calibration with the nozzle as the probe, plus automatic mesh bed levelling over the print area[4]
Filament Handling & Detection
Filament runout sensor (type, location)Not documentedBuilt-in Hall-effect filament sensor supporting automatic filament loading[4]
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Not documentedCustom 32-bit xBuddy board with STM32, designed and built in-house, with a separate extruder breakout board[4]
PSU (brand, wattage, rail voltage)Not documented240 W Delta PSU with hardware power panic[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 slicers are Voxeldance Tango and CHITUBOX; STL and OBJ accepted[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][8]
Connectivity, UI & Camera
Display: size, type, touch?3.5-inch resistive touchscreen (control panel — not the masking LCD, see W1)[1]3.5-inch 65k-colour graphic screen[4]
On-device UI capabilities (model preview, per-object controls, etc.)Not documentedOn-device colour UI with one-click printing and status LEDs; Prusa Link is integrated and Prusa Connect adds remote printing[4]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveUSB only — no Wi-Fi on this model[1]Ethernet built in, optional ESP Wi-Fi module delivered with the printer, USB drive; print files can also arrive over LAN or the internet via Prusa Connect[4]
Materials Support
Officially supported filament list405 nm photopolymer resin. Elegoo does not publish a resin compatibility list on this listing[1]Prusa's launch table says "any thermoplastic including Nylon and Polycarbonate"; the enclosure is still needed in practice for ABS/ASA-class materials[4]
Safety
Thermal runaway protection (verify in firmware source if at all possible)Not documentedxBuddy hardware overcurrent protection disconnects heater and heatbed power when total current exceeds 15 A; firmware is open-source and auditable[4][9]
Firmware safety limits (max temp cutoffs — exact values)Intelligent overheating protection stops printing 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][8]
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.
