Neptune 3 Pro

Elegoo 2022
Fused filament fabrication (FFF/FDM) F2 · Intermediate

The Elegoo Neptune 3 Pro is positioned in the tier for hobbyists and advanced beginners, offering an excellent balance between ease of use and mechanical performance. The Cartesian structure is reinforced by a dual-motor Z-axis, ensuring stability during prints that utilize the maximum height. The dual-gear direct drive extruder ensures reliable handling of flexible filaments like TPU, in addition to standard PLA and PETG. The inclusion of 36-point automatic bed leveling via an inductive sensor significantly reduces manual calibration time. While it does not reach the speeds or temperatures of industrial models, it fully covers the needs of domestic prototyping and modeling.
