Variants & sibling models — and how to tell them apart (spec-contamination risk)Superseded by the Centauri Carbon 2, which raises the nozzle ceiling to 350 C and swaps the nano mineral crystal filter for a HEPA plus coconut-shell carbon stack, adds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[5][6][1]Sold semi-assembled and, historically, as a kit; also offered in an Enclosure Bundle. Distinguish from the larger i3-family machines - the MINI+ is Bowden-fed with 2209 drivers, a 280 C nozzle ceiling and a 100 C bed, all lower than the MK3S+/MK4S. Note that Prusa's own MINI+ page carries an "Awards & Press Reviews" paragraph that is entirely about the MK3S, not the MINI+[2][7]
Market position: superseded?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Superseded within ELEGOO's own line-up: the US store's Centauri section in Aug 2026 lists the Centauri Carbon 2 Combo, Centauri 2 Combo, Centauri Carbon 2 and an emoji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[8]Not documented
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable256 x 256 x 256 mm; printing platform 260 x 260 mm[1]180 x 180 x 180 mm (manufacturer figure)[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)398 x 404 x 490 mm[1]380 x 330 x 380 mm (X x Y x Z), stated without the spool holder and external PSU - the external PSU brick needs additional desk space[2]

Z-axis: leadscrew count & type, sync mechanism, anti-backlashThree 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 2209 silent stepper drivers, with sensorless homing on the X and Y axes[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 speed250 mm/s recommended printing speed (manufacturer figure)[1]Not documented
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 nameDual-gear direct extruder with one fan[1]Bowden extruder with 3:1 gearing - the only current Prusa FFF machine that is not direct drive[2]
Gear ratio & drive gear materialNot documented3:1 extruder gearing[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][5]280 C claimed max nozzle temperature - lower than the 290-300 C of the i3-family machines[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit110 C max heated bed temperature at 25 C ambient[1]100 C max heatbed temperature[2]
Bed surface (material, texture, coating), single/double-sidedDual-sided spring steel sheet - textured PEI on one face, a PLA-specific surface on the other[1]Removable magnetic steel sheets in several surface 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 with no temperature drift, driving automatic mesh bed levelling[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][5]Not documented
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designPart 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]Custom 32-bit board of Prusa's Buddy family; the MINI/MINI+ is covered by the same Prusa-Firmware-Buddy source tree as the MK4, XL and CORE One. The exact board revision is not given on the product page[2][9]
Total rated power draw1100 W at 220 V, 350 W at 110 V rated; 24 V output; 100-240 VAC input[1]Not documented
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]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][10]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch colour capacitive touch screen[1]2.8-inch 65k-colour graphic screen with G-code preview[2]

Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Chamber camera fitted, with real-time monitoring and time-lapse; dual built-in LED strips[1]Not documented
Calibration Routines & QoL
Assembly level & time from unbox to first printNot documentedSemi-assembled: Prusa ships it in a small number of pre-built sections; also historically sold as a full kit[2]
Materials Support
Officially supported filament listCarbon/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, Woodfill and other filled materials (Prusa's own list; the 100 C bed and open frame are the practical limit for ABS/ASA)[2]
Safety
Thermal runaway protection (verify in firmware source if at all possible)Not documentedThree thermistors and fan RPM sensors are fitted, and the firmware is open-source and auditable (Prusa-Firmware-Buddy); Prusa does not describe the thermal-runaway implementation on the product page[2][9]
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][10]

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.
