|---|---|---|
| Identity | ||
| Brand | Prusa Research | QIDI |
| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Prusa CORE One+ (Gen 2). Prusa's e-shop lists "Prusa CORE One+ (Gen 2)" and "Prusa CORE One+ (Gen 2) Assembly kit"[1][2] | QIDI Max4, sold as "Max4 High-Temp 3D Printer"[3][4] |
| Release date (announcement and actual shipping) | 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[5] | Not published on QIDI's product page; the machine is listed as the current replacement for the discontinued X-Max 3 (checked Aug 2026)[3][6] |
| Street price (USD; dated snapshot per entry) | $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[2][1] | $1,099.00 standard on us.qidi3d.com against a $1,149.00 compare-at price, checked Aug 2026. Variants: Polar Cooler bundle $1,249.00 (was $1,348.00), Max4 Combo $1,249.00 (was $1,299.00), Combo + Polar Cooler $1,399.00[3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | 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[1][2][7] | Four variants at the US store: Standard, Polar Cooler bundle, Combo (adds QIDI Box), Combo + Polar Cooler. Direct replacement for the X-Max 3, which it differs from on every headline figure: 390x390x340 vs 325x325x315, 800 vs 600 mm/s, 370 vs 350 °C. Do not carry X-Max 3 specs across[3][6] |
| Market position: superseded? successor announced? | Current model and Prusa's mainstream enclosed machine, above the MK4S and below the CORE One L+[2] | Current large-format flagship as of Aug 2026; QIDI's X-Max 3 page directs buyers here[3][6] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 250 x 220 x 270 mm (manufacturer figure)[1] | 390 x 390 x 340 mm advertised[3][4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 415 x 444 x 555 mm (X x Y x Z)[1] | 558 x 578 x 612 mm[4] |
| Net weight (kg) | 22.5 kg[1] | 46.5 kg net[4] |
| Frame construction & material | All-steel exoskeleton (Prusa's own comparison wording, against "aluminium extrusions and frame" for the MK4S)[8] | Enclosed CoreXY chassis; QIDI does not publish a frame-material breakdown[3] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed with a door-open sensor and active chamber temperature control up to 55 C; HEPA/advanced filtration is an optional add-on[1][8] | Fully enclosed with a 3-in-1 air filter (G3 pre-filter + H12 HEPA + coconut-shell activated carbon)[4] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Active chamber heating, maximum 55 C (manufacturer figure)[1] | 65 °C, independent active chamber heating (manufacturer claim), with a 4-pin PWM chamber fan with RPM feedback[4] |

| Max volumetric flow claimed (mm³/s) | Not documented | 40 mm3/s rated flow (manufacturer claim)[4] |
| Vibration Compensation / Input Shaping | ||
| Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary) | Not documented | Input shaper listed as a feature[4] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Nextruder direct drive, E3D V6 compatible with an adapter; planetary gear system with a 10:1 ratio; aluminium heatsink and all-metal hotend[1] | Direct drive, dual hardened-steel gears, 8.9:1 reduction[4] |
| Gear ratio & drive gear material | 10:1 planetary gearbox[1] | 8.9:1; drive gears hardened steel[4] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Quick-swap nozzle system; high-flow Prusa brass CHT 0.4 mm nozzle supplied. An optional HT hotend raises the ceiling to 400 C[1] | Multi-metal hotend with a ceramic heater and a 0.4 mm bimetal nozzle; ceramic throat[4] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 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[1][5] | <=370 °C claimed[3][4] |
| Heated Bed & Surface | ||

| Multi-material/multi-color capability or official upgrade path | MMU3 for five filaments, or the INDX system for up to eight, both officially supported[1] | QIDI Box multi-colour unit supported; sold bundled as the Max4 Combo[3][4] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | High-performance turbine part-cooling fan with 360-degree cooling, the same arrangement as the MK4S[1] | Toolhead, model and auxiliary fans are all 4-pin PWM with RPM feedback; mainboard and chamber fans are closed-loop, chamber fan high-power turbo[4] |
| Chamber/exhaust fan & filtration (activated carbon / HEPA) | Not documented | 3-in-1 filtration: G3 pre-filter, H12 HEPA, coconut-shell activated carbon[4] |
| Electronics & Power | ||

| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | The xBuddy platform carries hardware overcurrent protection that cuts heater and heatbed power above 15 A, and the firmware is open-source and auditable[10][9] | Not documented |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | 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[11][8] | 1-year coverage, lifetime tech guidance, 14-day no-reason return[3] |
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.
