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]$309.00 on us.elegoo.com, Aug 2026, against a compare-at price of $425.00. Only a Ribbon-Cable printhead variant is listed for the Plus, unlike the Neptune 4 and 4 Max which also offer a Type-C version[4][5][3]
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][2][3]Middle model of the Neptune 4 family. Against the base Neptune 4: bigger (320 x 320 x 385 mm), but a lower bed ceiling (100 C rather than 110 C) and much lower acceleration (12000 rather than 20000 mm/s2). Against the Max: smaller and lighter (14.4 kg against 18.1 kg) but with a higher bed ceiling (100 C against 85 C) and higher acceleration (12000 against 8000). Its Z drive is 2 lead screws with 2 tie rods, where the Centauri machines use 3 lead screws[2][6][1][7]

Speed & Acceleration
Max print speed (claimed, mm/s)500 mm/s max toolhead speed (manufacturer claim)[1]30-500 mm/s printing speed, with 250 mm/s given by ELEGOO as the recommended figure - the 500 mm/s number is a ceiling, not a working speed[2]
Recommended/typical print speed250 mm/s recommended printing speed against the 500 mm/s ceiling (ELEGOO's own figure); default acceleration is 4000 mm/s2[8]250 mm/s recommended printing speed (manufacturer figure)[2]
Max acceleration (claimed, mm/s²)8000 mm/s2 max toolhead acceleration (manufacturer claim) - the lowest in the Neptune 4 family[1]12000 mm/s2 maximum acceleration; default acceleration 5000 mm/s2[2]

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]100 C max heated bed temperature at 25 C ambient[2]
Bed surface (material, texture, coating), single/double-sidedPEI spring steel sheet, now upgraded to a dual-sided textured PEI + PLA-specific surface; platform 430 x 430 mm[8]PEI spring steel sheet; ELEGOO notes it is now upgraded to a dual-sided textured PEI + PLA-specific surface[2]

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[8]Operating sound is published as 65 dB or less - a manufacturer figure with no measuring distance or method given, so it is not comparable with a reviewer's dB reading[2]
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[9]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.

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.
