| Property | ELEGOO Neptune 3 ProBEDSLINGER | QIDI Max4COREXY |
|---|---|---|
| Identity | ||
| Brand | ELEGOO | QIDI |
| Class | BEDSLINGER | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Neptune 3 Pro[1] | QIDI Max4, sold as "Max4 High-Temp 3D Printer"[2][3] |
| Release date (announcement and actual shipping) | Listed on the ELEGOO US store from 11 November 2022 (Shopify publish date)[4] | Not published on QIDI's product page; the machine is listed as the current replacement for the discontinued X-Max 3 (checked Aug 2026)[2][5] |
| Street price (USD; dated snapshot per entry) | $259.99 on us.elegoo.com, Aug 2026, with the compare-at price also $259.99 - notably more than the newer and far faster Neptune 4 at $219[4][6] | $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[2] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | The last Neptune 3 still listed; the 3 Plus and 3 Max are gone from the store's Neptune section. Do not read Neptune 4 figures onto it: the 3 Pro runs Marlin, not Klipper, tops out at 180 mm/s rather than 500, uses a 36-point mesh rather than 121-point, and its nozzle stops at 260 C rather than 300 C. Its machine size, 475 x 445 x 515 mm, is identical to the Neptune 4's, so body dimensions will not tell them apart[1][7][8] | 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[2][5] |
| Market position: superseded? successor announced? | Superseded by the Neptune 4 series and, in ELEGOO's current marketing, by the Centauri line[8] | Current large-format flagship as of Aug 2026; QIDI's X-Max 3 page directs buyers here[2][5] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 225 x 225 x 280 mm; printing platform 235 x 235 mm[1] | 390 x 390 x 340 mm advertised[2][3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 475 x 445 x 515 mm - the same body as the Neptune 4. ELEGOO's maximum size for machine activity is 475 x 580 x 725 mm[1][7] | 558 x 578 x 612 mm[3] |
| Net weight (kg) | 8.1 kg net, 10.15 kg gross[1] | 46.5 kg net[3] |

| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Two lead screws[1] | 2 mm lead Z screw with an anti-backlash nut[2] |
| Stepper motors (frame size, step angle, brand if known) | Not documented | FOC closed-loop stepper motors[3] |

| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 30-180 mm/s, with 60 mm/s given by ELEGOO as the recommended speed - a pre-Klipper machine, and the slowest in this file apart from the OrangeStorm Giga[1] | 800 mm/s (manufacturer claim, maximum)[3] |
| Recommended/typical print speed | 60 mm/s recommended printing speed (manufacturer figure)[1] | Not documented |
| Max acceleration (claimed, mm/s²) | Not documented | 30,000 mm/s2 (manufacturer claim, maximum)[3] |

| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 100 C max heated bed temperature at 25 C ambient[1] | <=120 °C claimed on a 390 x 390 mm bed QIDI markets as ultra-uniform (no thermal imaging published)[2][3] |
| Bed surface (material, texture, coating), single/double-sided | PEI spring steel sheet[1] | Aluminium plate with silicone heater; double-sided magnetic PEI build plate[3] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | 36-point auto-levelling (the Neptune 4 family moved to 121 points)[1][9] | Automatic levelling; probe technology not named by QIDI[3] |

| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Operating sound published as 48 dB or less - a manufacturer figure with no distance or method stated[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[10] | 1-year coverage, lifetime tech guidance, 14-day no-reason return[2] |
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.
