Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)ELEGOO Neptune 4 Max[1]Prusa CORE One L+[2]
Release date (announcement and actual shipping)Listed on the ELEGOO US store from 20 September 2023 (Shopify publish date)[3]The CORE One L+ refresh was announced on 13 August 2026 and went on sale immediately, with the first assembled units shipping at once; it adds GT1.5 belts and an integrated nozzle wiper to the CORE One L[4]
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]$1,850.93 on prusa3d.com, Aug 2026; $1,925.00 with the Advanced Filtration bundle. Prusa's own comparison text on the CORE One+ page quotes "from $1,799", which does not match the live e-shop price[5][6]
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][7][8][3]Larger sibling of the CORE One+ (Gen 2): 300 x 300 x 330 mm against 250 x 220 x 270 mm, 60 C chamber against 55 C, 21.9 kg against 22.5 kg (the L is the lighter of the two despite being larger). A CORE One L to CORE One L+ upgrade kit exists, so "CORE One L" and "CORE One L+" are different revisions. A Critical Infrastructure Edition is also listed[2][6][5]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable420 x 420 x 480 mm; printing platform 430 x 430 mm[1]300 x 300 x 330 mm, which Prusa states as 29.7 litres[2]
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]469 x 521 x 635 mm[2]
Net weight (kg)18.1 kg net, 21.8 kg gross[1]21.9 kg (48.3 lb)[2]
Frame construction & materialCNC-machined aluminium extrusion frame[1]Not documented
Enclosure: open / enclosed; panel material; door/lidOpen frame, no enclosure[1]Fully enclosed with a chamber door-open sensor and an active convection heated chamber up to 60 C; advanced filtration is an optional add-on[2]
Passive chamber temperature reached (if enclosed; measured values preferred)Not documentedActive convection chamber heating, maximum 60 C (manufacturer figure)[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Cartesian i3 bed-slinger[1]CoreXY - stated in Prusa's CORE One+ comparison table[6]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashTwo lead screws with two tie rods[9]Not documented
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)"Silent Drive (All Axes)"; no driver part number published[9]Trinamic drivers on the custom xBuddy mainboard (Prusa's CORE One L+ specification says "custom 32-bit xBuddy mainboard with STM32 processor & Trinamic drivers"; it does not give the driver part number)[2]
Speed & Acceleration
Max print speed (claimed, mm/s)500 mm/s max toolhead speed (manufacturer claim)[1]Not documented
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[9]Not documented
Max acceleration (claimed, mm/s²)8000 mm/s2 max toolhead acceleration (manufacturer claim) - the lowest in the Neptune 4 family[1]Not documented
Vibration Compensation / Input Shaping
Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary)Not documentedInput Shaper and Phase Stepping with an integrated accelerometer[2]
Extruder
Type (direct drive / bowden) & design nameDual-gear direct extruder with 2 fans[9]Nextruder direct drive with a 10:1 planetary gear system; all-metal hotend with an aluminium heatsink and a tool-free quick-swap nozzle system[2]
Gear ratio & drive gear materialNot documented10:1 planetary gearbox[2]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Brass nozzle, 0.4 mm, with a titanium-alloy heat break[9]Tool-free quick-swap nozzle system; Prusa brass high-flow CHT 0.4 mm pre-mounted plus an abrasive-resistant 0.4 mm nozzle in the box[2]
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max nozzle temperature[1]290 C claimed max nozzle temperature. The optional HT hotend that raises this to 400 C was announced for September 2026 availability, so it is not a shipping specification as of Aug 2026[2][4]
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]120 C max heatbed temperature[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[9]Magnetic heatbed with removable dual-sided PEI spring-steel sheets; a satin powder-coated sheet is supplied[2]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Manual levelling combined with 121-point auto-levelling[9]High-precision load-cell sensor - fully automatic first-layer calibration and mesh bed levelling restricted to the print area[2]
Filament Handling & Detection
Filament runout sensor (type, location)Filament detection and power-loss resume printing[1]Two filament sensors, plus a chamber door-open sensor and five Semitec thermistors[2]

Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Klipper[9]Open-source Prusa Buddy firmware. The source tree (prusa3d/Prusa-Firmware-Buddy on GitHub) explicitly covers the Original Prusa MINI/MINI+, MK4, XL and CORE One and was last pushed to in August 2026. Updates are applied from a USB drive, through Prusa Connect or through the Prusa mobile app[10][11]
Connectivity, UI & Camera

Materials Support
Officially supported filament listPLA, TPU, PETG, ABS, ASA, Nylon - but note the 85 C bed ceiling against ABS and ASA[1]PLA, PETG, Flex, PVA, PC, PP, CPE, PVB, and with Advanced Filtration also ABS, ASA, HIPS and PA[2]
Safety
Thermal runaway protection (verify in firmware source if at all possible)Not documentedOpen-source firmware on the xBuddy platform, which carries hardware overcurrent protection cutting heater and heatbed power above 15 A[12][10]
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[9]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[13]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[14][11]

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.
