Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)ELEGOO OrangeStorm Giga[1]Original Prusa MK4S (Prusa Research, Prague). Sold as "Original Prusa MK4S 3D Printer" and "Original Prusa MK4S 3D Printer kit"[2][3]
Release date (announcement and actual shipping)Listed on the ELEGOO US store from 17 October 2024 (Shopify publish date)[4]Announced and available to order on 12 August 2024, the date of Prusa's launch blog post, with assembled printers, kits and an MK4S/MMU3 bundle in stock at announcement[5]
Street price (USD; dated snapshot per entry)$2,499.00 on us.elegoo.com, Aug 2026, against a compare-at price of $3,125.00[4]$925.00 assembled, $657.40 as a kit, on prusa3d.com, Aug 2026. Bundles: $1,171.11 with MMU3, $1,185.65 with the Enclosure, $1,438.33 with both[3][2]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Sold bare and in bundles; dual-printhead and quad-printhead upgrade kits are separate products, so a Giga's nozzle count depends on which kit was bought. The four printheads sit on the same X axis and print four copies of the same model in parallel (or the same model in four colours) - this is not an IDEX or a toolchanger[1][6]The MK4S is a revision of the MK4, not a new platform: Prusa sold a $99 upgrade kit that gives an MK4 all of the MK4S features (360-degree turbine part cooling, high-flow CHT nozzle, firmware and profile changes). Watch the published nozzle ceiling: Prusa's MK4 announcement table says 300 C, while the MK4S product page says 290 C. Related family members are the MK3.5 and MK3.9 upgrades of the MK3S+, which are not the same machine. With the MMU3 the standard (non-high-flow) nozzle is the recommended one[5][7][2]
Market position: superseded? successor announced?Not documentedStill sold in Aug 2026 as the entry point to the Nextruder line, positioned below the enclosed CORE One+ (Gen 2). Prusa also sells an MK4S-to-CORE One+ (Gen 2) conversion kit[3][2]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable800 x 800 x 1000 mm; the platform is 820 x 820 mm made up of four independent 410 x 410 mm PEI plates[1]250 x 210 x 220 mm (manufacturer figure)[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)1224 x 1164 x 1425 mm; ELEGOO's maximum size for machine activity is 1224 x 1520 x 1570 mm. This is a floor-standing machine, not a desktop one[1]500 x 550 x 400 mm (X x Y x Z), stated without the spool holder[2]
Net weight (kg)104 kg net, 145 kg gross, and it ships in multiple crates (bottom + XY axis components, then two Z-axis components)[1]7 kg (without spool)[2]
Frame construction & materialCNC-machined aluminium extrusion frame; the X and Y axes run on linear guides and the machine sits on carbon steel round bases with rubber anti-slip pads[1]Aluminium extrusions and frame. Prusa's MK4 announcement records that the cut-aluminium frame of the MK3S+ was replaced by a die-cast aluminium frame for the MK4 platform, which the MK4S inherits[2][7]
Enclosure: open / enclosed; panel material; door/lidOpen frame, no enclosure[1]Open frame. The Original Prusa Enclosure is a separate add-on and raises the achievable chamber temperature to 45 C; there is no active chamber heating[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Cartesian gantry with a fixed bed - the printhead moves in X and Y on linear guides and the gantry moves in Z, so nothing about the bed moves during a print[1]Cartesian bed-slinger - Prusa's own comparison table gives "Cartesian" for the MK4S against "CoreXY" for the CORE One and CORE One L[8]
X-axis guide type (rods / linear rails / V-wheels; size)Linear guide on the X axis[1]Not documented
Y-axis guide typeLinear guide on the Y axis[1]Not documented
Z-axis: leadscrew count & type, sync mechanism, anti-backlashFour lead screws with four linear guide rods[9]Not documented
Belts (type, width, e.g. Gates?)X/Y belts with knob-adjustable tensioners[1]Not documented
Stepper motors (frame size, step angle, brand if known)Not documented0.9 degree X and Y stepper motors, which Prusa states are used to prevent vertical fine artefacts[2]
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)"Silent Drive (All Axes)"; no driver part number published[9]Trinamic 2130. The MK4 announcement is more specific: TMC2130-LA drivers on the xBuddy board[2][7]
Speed & Acceleration
Max print speed (claimed, mm/s)30-300 mm/s, with 150 mm/s given by ELEGOO as the recommended speed - far below the 500-600 mm/s claimed for desktop machines, which is the honest consequence of moving a gantry this size[1][9]Not documented
Recommended/typical print speed150 mm/s recommended printing speed (manufacturer figure)[9]Not documented
Max acceleration (claimed, mm/s²)5000 mm/s2 maximum acceleration, which is also the default - four times lower than the Centauri machines[9]Not documented
Extruder
Type (direct drive / bowden) & design nameDual-gear direct extruder with 2 fans[9]Nextruder, direct drive, E3D V6 compatible with an adapter; Nextruder planetary gear system with a 10:1 gearbox ratio; aluminium heatsink and all-metal filament path[2]
Gear ratio & drive gear materialNot documented10:1 planetary gearbox in the Nextruder[2]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Brass nozzle - and note the standard diameter here is 0.6 mm, not the 0.4 mm used across the rest of the ELEGOO range[9]Quick-swap Prusa nozzle system with an all-metal filament path; the MK4S ships with the high-flow Prusa brass CHT 0.4 mm nozzle. Standard (non-CHT) Prusa nozzles remain usable and are the recommended choice with the MMU3[2][5]
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max nozzle temperature[1]290 C claimed max nozzle temperature on the MK4S product page (Prusa's MK4 announcement table gave 300 C for the MK4)[2][7]
Heated Bed & Surface
Max bed temp claimed AND firmware limit100 C max heated bed temperature at 25 C ambient, across four independent 410 x 410 mm PEI magnetic high-temperature platforms[1]120 C max heatbed temperature (manufacturer figure)[2]
Bed surface (material, texture, coating), single/double-sidedFour independent 410 x 410 mm PEI magnetic platforms rather than one large plate[1]Magnetic heatbed with removable double-sided PEI spring-steel sheets; smooth PEI sheet supplied[2]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Manual levelling combined with 100-point auto-levelling (the desktop ELEGOO machines use a 121-point mesh)[9][10]Load-cell sensor in the toolhead - the nozzle itself is the probe. First-layer calibration and mesh bed levelling over the print area only are fully automatic, with no Live Adjust Z step[2][7]
Filament Handling & Detection
Filament runout sensor (type, location)Filament detection and power-loss resume printing[1]Filament sensor fitted as standard; on the MK4 platform this is a built-in Hall sensor that also drives automatic filament loading[2][7]
Multi-material/multi-color capability or official upgrade pathUp to three additional printheads can be added on the X axis for four-nozzle simultaneous printing - four copies of one model at once, or the same model in four colours[1]Not documented
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designNot documentedHigh-performance turbine part-cooling fan with a 360-degree air-delivery duct - the headline change from the MK4, derived from work on Prusa's HT90 industrial machine. Fan RPM is monitored in firmware[2][5]
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)"Klipper High-Speed Quiet Motherboard" is all ELEGOO publishes[9]Custom 32-bit xBuddy board with an STM32 MCU, designed, manufactured and tested in-house, plus a custom extruder breakout board for fans and thermistors[2][7]
PSU (brand, wattage, rail voltage)Not documented240 W PSU custom-made by Delta with hardware power-panic support[2]
Total rated power draw1530 W with a single head, plus 100 W per additional head, to a stated maximum of 1830 W with four nozzles; 100-120 VAC / 220-240 VAC, 50/60 Hz[1][9]Power consumption 80 W on PLA settings, 120 W on ABS settings (manufacturer figures)[2]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Klipper[9]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[11][2]
Connectivity, UI & Camera
Display: size, type, touch?10.1-inch colour capacitive touch screen - by far the largest in the ELEGOO range[9]3.5-inch 65k-colour graphic screen with touch control[2]
On-device UI capabilities (model preview, per-object controls, etc.)Colour capacitive touch UI; ElegooSlicer recommended, Orca and Cura supported[9]On-device colour UI with G-code preview and one-click printing; remote control and firmware updates through Prusa Connect and the Prusa mobile app[2]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveWi-Fi, USB and LAN file transfer[1]Ethernet, Wi-Fi via the ESP module delivered with the printer, USB drive for print files, plus an NFC receiver used to hand over Wi-Fi credentials from the phone app[2][8][5]
Calibration Routines & QoL
Assembly level & time from unbox to first printNot documentedSold both assembled (plug-and-print after a 10-minute self-test) and as an assembly kit[5]
Materials Support
Officially supported filament listThe product page lists PLA, PETG and TPU; ELEGOO's compare page adds Nylon to the same machine. Either way it is a much shorter list than the Neptune bed-slingers[1][9]PLA, PETG, Flex, PVA, PC, PP, CPE, PVB; ABS, ASA, HIPS and PA only when using the Original Prusa Enclosure with the filtration add-on[2]
Safety
Thermal runaway protection (verify in firmware source if at all possible)Not documentedThe xBuddy platform carries hardware overcurrent protection that disconnects heater and heatbed power when total current exceeds 15 A, and the firmware is open-source and auditable. Prusa also shipped Thermal Model protection to the earlier MK3 line[7][11]
Certifications (UL/ETL/CE/FCC — verify, don't assume)Not documentedPrusa states the MK4S is the first consumer 3D printer to receive UL GREENGUARD certification[2]
Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)12 months on brand-new machines and parts, but ELEGOO's own table excludes a long list of parts from that: PEI plate / build plate / nozzle kit / PTFE tube / heater / thermistor / hot end / packaging / manual / tools carry no warranty at all, and the extruder, extruder kit and printhead kit get 6 months. Certified pre-owned machines carry no warranty[12]2-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[13][2]
Spare parts availability & pricing (nozzle, hotend, plate, board, belts)Not documentedPrusa cites a perfect 30/30 print-quality score from TechRadar and a CNET "Best Printer for Quality" title; these are quoted on Prusa's own page and were not verified against the original reviews here[2]

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.
