| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Mars 5. Elegoo's own product handle spells the configuration out: mars-5-4k-6-6inch-monochrome-lcd-resin-3d-printer[1][2][3] | Prusa CORE One+ (Gen 2). Prusa's e-shop lists "Prusa CORE One+ (Gen 2)" and "Prusa CORE One+ (Gen 2) Assembly kit"[4][5] |
| Release date (announcement and actual shipping) | Not documented | The CORE One+ (Gen 2) refresh was announced on 13 August 2026, on sale immediately, with the first assembled units shipping at once and kits, upgrade kits and individual parts rolling out over the following weeks. It succeeds the CORE One and CORE One+ on the same platform[6] |
| Street price (USD; dated snapshot per entry) | $179.00 on us.elegoo.com against a $225.00 compare-at price (20% off), in stock, checked Aug 2026. The live product feed shows the same $179.00[2][3] | $1,202.78 assembled, $925.00 as an assembly kit, on prusa3d.com, Aug 2026. Bundles run to $1,301.85 with camera and advanced filtration. Prusa's own marketing table on the same page quotes "from $1,299" assembled, which does not match the live e-shop price[5][4] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Sold beside the Mars 5 Ultra, which is a materially different machine: 7-inch 9K masking LCD vs 6.6-inch 4K, 18 um vs 35 um pixels, 150 vs 70 mm/h, a 4.0-inch capacitive control screen vs 3.5-inch resistive, and Wi-Fi (the plain Mars 5 is USB only). Elegoo lists ten further Mars 5 / Mars 5 Ultra bundle SKUs pairing the printers with Mercury wash-and-cure stations at $302-$432; those are not printer prices[1][7][2][3] | Three generations share the CORE One name: the original CORE One, the CORE One+, and the CORE One+ (Gen 2), with paid upgrade kits between them (CORE One+ to CORE One+ (Gen 2), and an MK4S to CORE One+ (Gen 2) conversion kit). The specifications recorded here are those published on Prusa's current CORE One+ (Gen 2) page and should not be assumed to hold for a first-generation CORE One. The INDX 4-tool and 8-tool machines are variants of the same product page, and the CORE One L is a larger, separate machine[4][5][8] |
| Market position: superseded? successor announced? | Not documented | Current model and Prusa's mainstream enclosed machine, above the MK4S and below the CORE One L+[5] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 143.43 x 89.6 x 150 mm[1] | 250 x 220 x 270 mm (manufacturer figure)[4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 230 x 230 x 433.5 mm[1] | 415 x 444 x 555 mm (X x Y x Z)[4] |
| Net weight (kg) | Approximately 6.6 kg[1] | 22.5 kg[4] |
| Frame construction & material | Metal frame with adjustable foot pads[1] | All-steel exoskeleton (Prusa's own comparison wording, against "aluminium extrusions and frame" for the MK4S)[9] |
| Enclosure: open / enclosed; panel material; door/lid | Open-frame MSLA with a removable UV-blocking cover[1] | Fully enclosed with a door-open sensor and active chamber temperature control up to 55 C; HEPA/advanced filtration is an optional add-on[4][9] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | Active chamber heating, maximum 55 C (manufacturer figure)[4] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | MSLA — UV LCD masked stereolithography. Single Z axis, build plate lifting straight out of the vat (no tilt-release on this model, unlike the Mars 5 Ultra)[1][7] | CoreXY - stated as such in Prusa's own comparison table against the Cartesian MK4S[4] |
| Stepper motors (frame size, step angle, brand if known) | Not documented | 0.9 degree X and Y stepper motors[4] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | Trinamic 2130[4] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Not documented | Nextruder direct drive, E3D V6 compatible with an adapter; planetary gear system with a 10:1 ratio; aluminium heatsink and all-metal hotend[4] |
| Gear ratio & drive gear material | Not documented | 10:1 planetary gearbox[4] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | Quick-swap nozzle system; high-flow Prusa brass CHT 0.4 mm nozzle supplied. An optional HT hotend raises the ceiling to 400 C[4] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | Not documented | 290 C claimed max nozzle temperature. Prusa's comparison table adds "400 C w/ HT" for the optional HT hotend, which its 13 August 2026 blog post says will only become available in September 2026 - so 400 C is a forthcoming option, not a shipping specification[4][6] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | Not documented | 120 C max heatbed temperature[4] |
| Bed surface (material, texture, coating), single/double-sided | Laser-engraved build plate with a quick-release design[1] | Magnetic heatbed with removable PEI spring-steel sheets; whole-bed heating regardless of object size[4] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Automatic levelling, one click. An intelligent mechanical sensor detects resin residue to prevent LCD damage[1] | Load-cell sensor - fully automatic first-layer calibration with the nozzle as the probe[4] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Not documented | Two filament sensors, plus a door sensor and five Semitec thermistors with fan RPM monitoring[4][9] |
| Multi-material/multi-color capability or official upgrade path | Not documented | MMU3 for five filaments, or the INDX system for up to eight, both officially supported[4] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Not documented | High-performance turbine part-cooling fan with 360-degree cooling, the same arrangement as the MK4S[4] |
| Electronics & Power | ||

| Total rated power draw | Not documented | Power consumption 90 W printing PLA, 110 W printing ABS (manufacturer figures)[4] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Not named by Elegoo. Supported slicers are Voxeldance Tango and CHITUBOX; STL and OBJ accepted[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[10][9] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 3.5-inch resistive touchscreen (control panel — not the masking LCD, see W1)[1] | 3.5-inch 65k-colour graphic screen with touch control[4] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Not documented | On-device touch UI; remote monitoring and printing through Prusa Connect and the Prusa mobile app; firmware updates from USB, Prusa Connect or the app[4] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | USB only — no Wi-Fi on this model[1] | Ethernet and Wi-Fi (NFC receiver plus an optional Wi-Fi module), USB drive for print files[4] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Not documented | Optional in-chamber camera solution (Buddy3D camera bundle listed at $1,237.03 against $1,202.78 for the bare printer)[4][5] |
| Materials Support | ||
| Officially supported filament list | 405 nm photopolymer resin. Elegoo does not publish a resin compatibility list on this listing[1] | PLA, PETG, Flex, PVA, PC, PP, CPE, PVB, and - as advanced materials in the heated chamber - ABS, ASA, HIPS and PA[4] |
| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | Not documented | The xBuddy platform carries hardware overcurrent protection that cuts heater and heatbed power above 15 A, and the firmware is open-source and auditable[11][10] |
| Firmware safety limits (max temp cutoffs — exact values) | Intelligent overheating protection stops printing above 80 °C[1] | Not documented |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | Not documented | 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][9] |

| Release film | PFA film with a non-stick surface. No rated life published[1] | Not documented |
| Resin vat & feeding | Replaceable resin tank with two pouring openings and screw caps. An intelligent mechanical sensor detects resin residue in the vat. Capacity not published; no auto-refill[1] | Not documented |
| Fume extraction | None fitted. Elegoo states compatibility with the separately sold MARS MATE air purifier for odour reduction[1] | Not documented |
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.
