ELEGOO Neptune 4 Plus FDM 3D Printer / 320 × 320 × 385mm Build Volume / Up to 500mm/s High-Speed Printing / Klipper Firmware / Auto Bed Leveling / Direct Drive Extruder / 300°C High-Temp Nozzle / ELE-50.201.015300B + FREE DELIVERY !

The Neptune 4 Plus is pre-installed with the high-performance Klipper firmware, enabling exceptional printing speeds up to 500 mm/s (standard 250 mm/s) and accelerations up to 12,000 mm/s². It natively supports advanced features such as input shaping and pressure advance calibration. Additionally, integrated acceleration sensors on the X and Y axes provide automatic calibration to dramatically enhance overall print quality.

Powered by a robust Klipper quiet motherboard, this printer features an ARM 64-bit 1.5GHz quad-core processor. The built-in 8GB ROM offers ample storage space for saving numerous design files locally. The system leverages input shaping and pressure advance technologies to drastically minimize printing artifacts, oozing, and stringing. Integrated resonance sensors on the X and Y axes actively auto-calibrate vibration compensation parameters for highly accurate outputs.

Expand your fabrication capabilities with a generous construction envelope of 320 × 320 × 385 mm (12.59 × 12.59 × 15.15 in). This large-scale printing area lets you produce oversized individual models or batch-print multiple smaller objects in a single job, greatly broadening your creative possibilities.

The 300 °C high-temperature nozzle assembly features an elongated hot end, a powerful 60 W ceramic heating element, and a durable brass heating block. This setup is fully capable of printing diverse filaments, including nylon. Furthermore, the automatic calibration of nozzle PID parameters optimizes thermal performance for stable and consistent extrusion.

Weighing only 290 g, the lightweight dual-gear direct extruder features a 5.2:1 reduction ratio to deliver smooth, reliable filament feeding. An all-titanium alloy throat pipe provides efficient heat dissipation to prevent nozzle blockages. Combined with a 60 W high-power ceramic heater and a brass block, it ensures uniform melting of filaments like PLA, PETG, ABS, ASA, TPU, and high-temp nylon. Active PID temperature calibration ensures accurate heat control for consistent printing results.

Seamlessly connect and manage your print jobs using Wi-Fi, Ethernet LAN, or a local USB drive. The network-ready setup supports web-based remote control and multi-machine network management, allowing you to orchestrate print farms and launch projects with simple, one-click file transfers.

To eliminate warping and structural deformation, the print head integrates a pair of thickened 4015 double-sided cooling fans and a 3010 ball-bearing blower fan for multi-angle heat dissipation. Additionally, two 6025 ball-bearing blower blowers mounted behind the print head rapidly cool freshly deposited layers to secure excellent overhang details.

This upgraded double-sided build plate offers specialized surface finishes to accommodate different materials. One side provides a specialized PLA surface designed for maximum adhesion and minimal warping at lower bed temperatures, while the reverse side features a classic textured PEI finish for strong grip and easy release of materials like ABS, TPU, and carbon-fiber blends.

The Z-axis incorporates dual lead screws, dual motors, and a dual-tie-rod structure for steady travel and precise layer registration. Smooth motion on the Y-axis is driven by a double Y-axis profile equipped with two rows of 3+3 POM V-guide wheels. Silent stepper drivers across all axes ensure quiet operations under 65 dB, while user-friendly hand-tensioning knobs on the X and Y axes make belt adjustments exceptionally easy.
