| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Centauri Carbon 2 Combo[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 9 August 2026 (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) | $399.00 on us.elegoo.com, Aug 2026, against a compare-at price of $449.00[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) | The Centauri Carbon 2 sold with the CANVAS multicolour unit. Every printing figure matches the bare Centauri Carbon 2; what changes is the body - 500 x 480 x 743 mm and 19.35 kg with CANVAS fitted - and CANVAS capability being listed Yes. Against the first-generation Centauri Carbon: 350 C nozzle rather than 320 C, clog detection added, and a HEPA plus coconut-shell carbon filter stack rather than the nano mineral crystal filter. An ELEGOO x emoji collaboration edition of the same machine is also listed[1][6][7][8] | 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][9][2] |
| Market position: superseded? successor announced? | Not documented | Still 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 usable | 256 x 256 x 256 mm; printing platform 260 x 260 mm[1] | 250 x 210 x 220 mm (manufacturer figure)[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 500 x 480 x 743 mm with the CANVAS unit fitted[1] | 500 x 550 x 400 mm (X x Y x Z), stated without the spool holder[2] |
| Net weight (kg) | 19.35 kg net, 23.8 kg gross[1] | 7 kg (without spool)[2] |
| Frame construction & material | Integrated die-cast aluminium construction (Centauri Carbon platform)[7] | 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][9] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed; the Centauri Carbon 2 uses a HEPA plus granulated coconut-shell activated-carbon filter stack rather than the first generation's nano mineral crystal filter, and adds a smart exhaust grille[6][7] | 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) | CoreXY[1] | Cartesian bed-slinger - Prusa's own comparison table gives "Cartesian" for the MK4S against "CoreXY" for the CORE One and CORE One L[10] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Three lead screws with three linear guide rods[1] | Not documented |
| Stepper motors (frame size, step angle, brand if known) | Not documented | 0.9 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[1] | Trinamic 2130. The MK4 announcement is more specific: TMC2130-LA drivers on the xBuddy board[2][9] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 500 mm/s or less, with 250 mm/s given as the recommended speed[1] | Not documented |
| Recommended/typical print speed | 250 mm/s recommended printing speed (manufacturer figure)[1] | Not documented |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 maximum acceleration; default 10000 mm/s2[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-gear direct extruder with one fan[1] | 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 material | Not documented | 10:1 planetary gearbox in the Nextruder[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Brass-hardened steel nozzle, 0.4 mm, titanium-alloy heat break[1] | 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) | 350 C claimed max nozzle temperature - 30 C above the first-generation Centauri Carbon[1][7] | 290 C claimed max nozzle temperature on the MK4S product page (Prusa's MK4 announcement table gave 300 C for the MK4)[2][9] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 110 C max heated bed temperature at 25 C ambient[1] | 120 C max heatbed temperature (manufacturer figure)[2] |
| Bed surface (material, texture, coating), single/double-sided | Dual-sided spring steel sheet, textured PEI plus a PLA-specific surface[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) | 121-point auto-levelling with full-auto calibration[1] | 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][9] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament run-out sensor, clog detection, auto filament unloading and power-loss recovery[1] | Filament sensor fitted as standard; on the MK4 platform this is a built-in Hall sensor that also drives automatic filament loading[2][9] |
| Multi-material/multi-color capability or official upgrade path | CANVAS multi-material capability included - the defining difference from the bare Centauri Carbon 2[1] | Not documented |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Not documented | High-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) | "Powerful Self-Developed Motherboard" is all ELEGOO publishes[1] | 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][9] |
| PSU (brand, wattage, rail voltage) | Not documented | 240 W PSU custom-made by Delta with hardware power-panic support[2] |
| Total rated power draw | 1100 W at 220 V, 350 W at 110 V rated; 24 V output[1] | 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) | ELEGOO OS; ElegooSlicer recommended, Orca and Cura supported[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[11][2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 5-inch colour capacitive touch screen (the first-generation Centauri Carbon used a 4.3-inch panel)[1][7] | 3.5-inch 65k-colour graphic screen with touch control[2] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Colour touch UI; LED lighting fitted; STL, OBJ, 3MF and STEP input[1] | 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-drive | USB and Wi-Fi[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][10][5] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Camera fitted[1] | Not documented |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Not documented | Sold both assembled (plug-and-print after a 10-minute self-test) and as an assembly kit[5] |
| Materials Support | ||
| Officially supported filament list | Ideal: PLA, PETG, ABS, ASA. Capable: TPU, PC, PA, PET and fibre-reinforced filaments[1] | 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 documented | The 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[9][11] |
| Certifications (UL/ETL/CE/FCC — verify, don't assume) | Not documented | Prusa states the MK4S is the first consumer 3D printer to receive UL GREENGUARD certification[2] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Operating sound published as 45 dB or less - a manufacturer figure with no distance or method stated, and 10 dB below the first-generation Centauri Carbon's published figure[1][7] | Not documented |
| 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 documented | Prusa 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.
