Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)ELEGOO Centauri Carbon 2 Combo[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 9 August 2026 (Shopify publish date)[3]Not documented
Street price (USD; dated snapshot per entry)$399.00 on us.elegoo.com, Aug 2026, against a compare-at price of $449.00[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)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][4][5][6]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][7][8][9]
Market position: superseded? successor announced?Not documentedSuperseded 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[8][9]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable256 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)500 x 480 x 743 mm with the CANVAS unit fitted[1]500 x 550 x 400 mm (X x Y x Z), without the spool holder[2]
Net weight (kg)19.35 kg net, 23.8 kg gross[1]7 kg (without spool)[2]
Frame construction & materialIntegrated die-cast aluminium construction (Centauri Carbon platform)[5]Cut aluminium frame - Prusa's MK4 announcement contrasts "the cut aluminum frame we used so far" with the MK4's new die-cast frame[8]
Enclosure: open / enclosed; panel material; door/lidFully 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[4][5]Open frame; the Original Prusa Enclosure is an optional separate product[8]
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[8]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashThree lead screws with three linear guide rods[1]Not documented
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)"Silent Drive (All Axes)"; no driver part number published[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 as the recommended speed[1]Not documented
Recommended/typical print speed250 mm/s recommended printing speed (manufacturer figure)[1]Not documented
Max travel speedNot 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 10000 mm/s2[1]Not documented
Extruder
Type (direct drive / bowden) & design nameDual-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, titanium-alloy heat break[1]Not documented
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][5]300 C claimed max nozzle temperature[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit110 C max heated bed temperature at 25 C ambient[1]120 C max heatbed temperature[2]
Bed surface (material, texture, coating), single/double-sidedDual-sided spring steel sheet, textured PEI plus a PLA-specific surface[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, clog detection, auto filament unloading and power-loss recovery[1]IR filament sensor built in, supporting filament auto-loading; the print pauses when filament runs out[2]
Multi-material/multi-color capability or official upgrade pathCANVAS multi-material capability included - the defining difference from the bare Centauri Carbon 2[1]Not documented
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)"Powerful Self-Developed Motherboard" is all ELEGOO publishes[1]EINSY RAMBo 8-bit board, co-developed with UltiMachine[2]
Input voltage (110/220 V, switch or auto)Not documentedCustom Delta PSU with hardware-based power panic[2]
Total rated power draw1100 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[2]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)ELEGOO OS; ElegooSlicer recommended, 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

On-device UI capabilities (model preview, per-object controls, etc.)Colour touch UI; LED lighting fitted; STL, OBJ, 3MF and STEP input[1]Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveUSB and Wi-Fi[1]SD card (16 GB card included); Ethernet and Wi-Fi only via an optional Raspberry Pi[2]

Materials Support
Officially supported filament listIdeal: PLA, PETG, ABS, ASA. Capable: TPU, PC, PA, PET and fibre-reinforced filaments[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 documentedPrusa shipped Thermal Model protection to the MK3 line as a firmware update shortly before the MK4 launch; the firmware is open-source and auditable[8][10]
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][5]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.
