| Property | ELEGOO Neptune 4 MaxBEDSLINGER | QIDI X-Max 3COREXY |
|---|---|---|
| Identity | ||
| Brand | ELEGOO | QIDI |
| Class | BEDSLINGER | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Neptune 4 Max[1] | QIDI X-Max 3, listed by QIDI as "Qidi Tech X-Max 3 3D Printer" and in navigation as X-Max3[2][3] |
| Release date (announcement and actual shipping) | Listed on the ELEGOO US store from 20 September 2023 (Shopify publish date)[4] | Not published by QIDI; the product page carries a discontinuation notice rather than a launch date (checked Aug 2026)[2] |
| Street price (USD; dated snapshot per entry) | $389.00 on us.elegoo.com, Aug 2026, against a compare-at price of $559.99; Ribbon-Cable and Type-C printhead variants are the same price[4] | $899.00 (from a $999.00 sale reference) on us.qidi3d.com but marked Sold Out and discontinued, checked Aug 2026. 3D Printers Online Store lists $1,099 USD, also out of stock[2][5] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Largest Neptune 4. The trade-off against the smaller models is easy to miss: the bed only reaches 85 C (against 100 C on the Plus and 110 C on the base Neptune 4) and acceleration is capped at 8000 mm/s2 (against 12000 and 20000), because of the mass of a 430 x 430 mm moving bed. Two printhead variants, Ribbon-Cable and Type-C, are sold under one SKU[1][6][7][4] | Same-generation siblings X-Plus 3 (280x280x270, 500 mm/s, 800 W) and X-Smart 3 (175x180x170, no chamber heating, 300 °C, 350 W). All three share the Cortex-A53 1.5 GHz / 1 GB DDR3 / 8 GB eMMC control board, so shared-board specs are not evidence of shared print specs. Replaced by the Max4[3][8][9][10] |
| Market position: superseded? successor announced? | Not documented | Discontinued and out of production; QIDI directs buyers to the Max4[2] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 420 x 420 x 480 mm; printing platform 430 x 430 mm[1] | 325 x 325 x 315 mm advertised[2][3][5] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 658 x 632 x 740 mm; ELEGOO's maximum size for machine activity is 658 x 950 x 960 mm including rack and tray - allow nearly a metre of depth and height[1] | 553 x 553 x 601 mm[3][5] |
| Net weight (kg) | 18.1 kg net, 21.8 kg gross[1] | 30.2 kg net[3][5] |
| Frame construction & material | CNC-machined aluminium extrusion frame[1] | Enclosed CoreXY chassis, fully assembled from the factory. QIDI does not publish a frame-material breakdown[3] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure[1] | Fully enclosed, with a chamber circulation blower and activated-carbon air filter[3] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | 65 °C maximum, independent chamber heating (manufacturer claim)[2][3] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Cartesian i3 bed-slinger[1] | CoreXY[3] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | Linear optical axis (polished steel rod) of high-strength steel[3] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Two lead screws with two tie rods[11] | Double Z axis[3] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | "Silent Drive (All Axes)"; no driver part number published[11] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 500 mm/s max toolhead speed (manufacturer claim)[1] | <=600 mm/s (manufacturer claim)[2][3][5] |
| Recommended/typical print speed | 250 mm/s recommended printing speed against the 500 mm/s ceiling (ELEGOO's own figure); default acceleration is 4000 mm/s2[11] | Not documented |
| Max acceleration (claimed, mm/s²) | 8000 mm/s2 max toolhead acceleration (manufacturer claim) - the lowest in the Neptune 4 family[1] | 20,000 mm/s2 (manufacturer claim)[2] |
| Max volumetric flow claimed (mm³/s) | Not documented | 35 mm3/s extruder flow (manufacturer claim)[3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-gear direct extruder with 2 fans[11] | High-flow direct-drive extruder; QIDI states a 9.5:1 gear ratio for this model[2][3] |
| Gear ratio & drive gear material | Not documented | 9.5:1[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Brass nozzle, 0.4 mm, with a titanium-alloy heat break[11] | Ceramic heating core. Two interchangeable nozzle-head sets shipped: copper alloy for standard materials, hardened steel for abrasives. 0.4 mm stock, 0.2/0.6/0.8 mm optional[2][3] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max nozzle temperature[1] | <=350 °C claimed[2][3][5] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 85 C max heated bed temperature at 25 C ambient - well below the 100-110 C of the smaller Neptunes, which limits ABS/ASA work despite them being on the compatibility list[1] | <=120 °C claimed[3][5] |
| Bed surface (material, texture, coating), single/double-sided | PEI spring steel sheet, now upgraded to a dual-sided textured PEI + PLA-specific surface; platform 430 x 430 mm[11] | Double-sided flexible magnetic plate (QIDI's "HF" plate)[2][3] |
| Leveling & Z-Offset | ||

| Materials Support | ||
| Officially supported filament list | PLA, TPU, PETG, ABS, ASA, Nylon - but note the 85 C bed ceiling against ABS and ASA[1] | ABS, PLA, PETG, TPU, nylon, carbon fibre, PC[5] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Operating sound published as 65 dB or less - a manufacturer figure with no distance or method stated[11] | 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[12] | 1-year coverage[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.
