| Brand | ELEGOO | Prusa Research |
| Class | COREXY | BEDSLINGER |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Centauri Carbon[1] | Original Prusa i3 MK3S+. The only version still listed in Aug 2026 is the "Original Prusa i3 MK3S+ 10th Anniversary Edition"[2] |
| Release date (announcement and actual shipping) | Listed on the ELEGOO US store from 17 February 2025 (Shopify publish date)[3] | Not documented |
| Street price (USD; dated snapshot per entry) | $419.99 on us.elegoo.com, Aug 2026, with the compare-at price also $419.99 (no discount running)[3] | $1,199.00 assembled, $899.00 as a kit, for the 10th Anniversary Edition on prusa3d.com, Aug 2026. This is above the price the standard MK3S+ sold at, so do not read it as the MK3S+ street price[2] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Superseded by the Centauri Carbon 2, which raises the nozzle ceiling to 350 C and swaps the nano mineral crystal filter for a HEPA plus coconut-shell carbon stack, adds clog detection, a smart exhaust grille and part-cooling-fan drop detection. The non-carbon Centauri and Centauri 2 are open-frame-oriented machines with a different filament list. Machine size 398 x 404 x 490 mm is shared with the Centauri 2, so body dimensions alone will not identify the model[4][5][1] | Only the 10th Anniversary Edition remains on sale; the standard MK3S+ is gone from Prusa's printer listing. Two official upgrade paths change the machine substantially and are frequently confused with it: MK3.5 (xBuddy board and new LCD, keeps the MK3 extruder) and MK3.9 (adds the Nextruder). A caution on Prusa's own pages: the "Awards & Press Reviews" paragraph about the MK3S is reproduced verbatim on the MINI+ product page, so award text found on a Prusa page does not necessarily belong to the printer on that page[2][6][7][8] |
| Market position: superseded? successor announced? | Superseded within ELEGOO's own line-up: the US store's Centauri section in Aug 2026 lists the Centauri Carbon 2 Combo, Centauri 2 Combo, Centauri Carbon 2 and an emoji collaboration edition[9] | Superseded by the MK4/MK4S line. Prusa cut MK3S+ prices at the MK4 launch in March 2023 and said it would keep selling the MK3S+ at a lower price and hold spare parts in stock[7][8] |
| 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] | 25 x 21 x 21 cm = 250 x 210 x 210 mm (manufacturer figure)[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 398 x 404 x 490 mm[1] | 500 x 550 x 400 mm (X x Y x Z), without the spool holder[2] |
| Net weight (kg) | 17.5 kg net, 21 kg gross[1] | 7 kg (without spool)[2] |
| Frame construction & material | Integrated die-cast aluminium construction, which ELEGOO credits for reduced vibration at speed[1] | Cut aluminium frame - Prusa's MK4 announcement contrasts "the cut aluminum frame we used so far" with the MK4's new die-cast frame[7] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed with a tempered glass door and top cover; a nano mineral crystal air filter, an auxiliary part-cooling fan and a chamber temperature regulator fan are fitted[1] | Open frame; the Original Prusa Enclosure is an optional separate product[7] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY[1] | Cartesian i3 bed-slinger. Prusa's MK4 announcement notes the MK3S+ Y-axis profiles and heatbed were among the few parts carried into the MK4[7] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Three lead screws with three linear guide rods[1] | Not documented |
| Belts (type, width, e.g. Gates?) | Semi-automatic belt tensioner[1] | Not documented |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | "Silent Drive (All Axes)" is all that is published; no driver part number is given[1] | Trinamic 2130 drivers at 256 microstepping on the EINSY RAMBo 8-bit board, co-developed with UltiMachine; sensorless homing on X and Y[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 500 mm/s or less, with 250 mm/s given by ELEGOO as the recommended speed[1] | Not documented |
| Recommended/typical print speed | 250 mm/s recommended printing speed (manufacturer figure)[1] | Not documented |
| Max travel speed | Not documented | "200+ mm/s" max travel speed (manufacturer figure, no measurement basis given)[2] |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 maximum acceleration; default acceleration 10000 mm/s2[1] | Not documented |
| Max volumetric flow claimed (mm³/s) | 32 mm3/s claimed flow rate (manufacturer figure; no test conditions published)[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-gear direct extruder with one fan[1] | Direct drive with Bondtech gears and an E3D V6 hotend[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Brass-hardened steel nozzle, 0.4 mm, with a titanium-alloy heat break; a heatbed nozzle wiper cleans it before each print[1] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 320 C claimed max nozzle temperature (the Centauri Carbon 2 raises this to 350 C)[1][4] | 300 C claimed max nozzle temperature[2] |
| 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[2] |
| Bed surface (material, texture, coating), single/double-sided | Dual-sided spring steel sheet - textured PEI on one face, a PLA-specific surface on the other[1] | Removable magnetic spring-steel sheets in several finishes; heatbed with cold-corner compensation[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] | SuperPINDA inductive probe (Prusa's temperature-drift-free replacement for the original PINDA), driving automatic mesh bed levelling and a self-test routine[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament run-out sensor, auto filament unloading, power-loss recovery and fan self-check; no clog detection on this model (the Centauri Carbon 2 adds it)[1][4] | IR filament sensor built in, supporting filament auto-loading; the print pauses when filament runs out[2] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Part cooling plus an auxiliary part-cooling fan and a chamber temperature regulator fan, with real-time fan self-checks[1] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | ELEGOO describes it only as a "Powerful Self-Developed Motherboard"; no board model or MCU is published[1] | EINSY RAMBo 8-bit board, co-developed with UltiMachine[2] |
| Input voltage (110/220 V, switch or auto) | Not documented | Custom Delta PSU with hardware-based power panic[2] |
| Total rated power draw | 1100 W at 220 V, 350 W at 110 V rated; 24 V output; 100-240 VAC input[1] | Power consumption 80 W on PLA settings, 120 W on ABS settings[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | ELEGOO OS with OTA updates; 8 GB of on-board storage. ElegooSlicer recommended, with Orca and Cura supported[1] | prusa3d/Prusa-Firmware on GitHub, GPL-3.0, whose README states it is "proudly based on Marlin 1.0.x" and covers the MK3S/MK3/MK2.5S/MK2.5 line; last pushed August 2025. Updated over USB from a PC[10] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch colour capacitive touch screen[1] | Not documented |
| On-device UI capabilities (model preview, per-object controls, etc.) | Colour touch UI; LED chamber lighting fitted; OTA firmware updates[1] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | USB and dual-band Wi-Fi for LAN transfers[1] | SD card (16 GB card included); Ethernet and Wi-Fi only via an optional Raspberry Pi[2] |

| Materials Support | ||
| Officially supported filament list | Carbon/glass fibre reinforced filaments, PLA, PETG, ABS, ASA, TPU, PET, PC, PA[1] | PLA, PETG, ASA, ABS, PC, CPE, PVA/BVOH, PVB, HIPS, PP, Flex, nGen, Nylon, carbon-filled, woodfill and other filled materials[2] |
| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | Not documented | Prusa shipped Thermal Model protection to the MK3 line as a firmware update shortly before the MK4 launch; the firmware is open-source and auditable[7][10] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Operating sound published as 55 dB or less - a manufacturer figure with no distance or method stated, so not comparable with an independently measured dB reading[1] | 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[11] | 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[12][13] |
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.
