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[3]$7,995.00 at MatterHackers, listed as currently unavailable, checked Aug 2026[2]
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][4][5][3]Not simply a longer TAZ Pro. The Long Bed ships the Asteroid 285 tool head with a 1.2 mm nozzle, a 0.3-0.9 mm equipped layer range, an 80 °C bed cap (vs 110 °C), 150 mm/s travel (vs 300) and BLTouch 32-point mesh levelling (vs 4-point contact). Bed material also differs: blue spring-steel magnetic flex rather than glass with PEI film[2][6]

Heated Bed & Surface
Max bed temp claimed AND firmware limit85 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]80 °C maximum bed temperature — notably lower than the base TAZ Pro[2]

Materials Support

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[8]1 year standard with extended options. Made in the USA[2]
Independently Measured Performance
Dimensional accuracy measurements (third-party, with numbers)Not documentedPositional resolution 0.01 mm in X/Y and 0.002 mm in Z (manufacturer specification)[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.
