Neptune 4 PRO 3D Printer (250-500 mm/h)

The ELEGOO Neptune 4 PRO is a high-speed FDM 3D printer equipped with pre-installed Klipper firmware and advanced features that deliver exceptional performance, precision, and convenience. Capable of reaching up to 500 mm/s (recommended speed of 250 mm/s), it is ideal for those looking for speed without sacrificing quality .

Equipped with a dual-gear direct-drive extruder (5.2:1) and a 300°C nozzle, the Neptune 4 PRO easily handles a wide range of filaments, from the most common (PLA, ABS, PETG) to high-temperature materials like nylon . Its efficient cooling system with multiple fans ensures solid layers even at extreme speeds.

The 121-point automatic bed leveling , combined with intelligent, segmented heating of the bed (up to 110°C), ensures greater adhesion, fewer errors, and energy savings. Additionally, it features smart sensors for resuming printing after power outages and filament end detection, offering greater safety and process continuity.
