ELEGOO Neptune 4 Pro 3D Printer

High-speed Klipper-powered FDM 3D printer with dual-gear direct drive extrusion,
300°C hotend, intelligent segmented heatbed, 121-point auto leveling, and powerful
multi-fan cooling for professional-quality printing.

Dual-Gear Direct Extruder

Powerful Filament Feeding. Superior Print Quality.

The ELEGOO Neptune 4 Pro features an advanced dual-gear direct-drive extruder
designed to provide consistent filament feeding and exceptional extrusion accuracy.
With a 5.2:1 reduction ratio, it delivers stronger gripping force and smooth material flow.

• Stronger Filament Grip
• Reduced Under-Extrusion Issues
• Improved Flexible Filament Printing
• Faster Response During High-Speed Printing
• Lightweight Design for Better Motion Control

Fast & Precise Extrusion

Optimized for High-Speed Printing

The Neptune 4 Pro combines its dual-gear direct-drive system with a high-flow hotend
architecture to deliver rapid and accurate material extrusion for prototypes, functional
parts, and decorative models.

• Smooth Material Flow
• Improved Dimensional Accuracy
• Consistent Layer Bonding
• Reduced Print Artifacts
• Excellent Surface Finish

300°C High-Temperature Nozzle Kit

Print More Materials with Confidence

Equipped with a 300°C high-temperature hotend, the Neptune 4 Pro supports a wide range
of engineering-grade and specialty filaments. The 60W ceramic heating element ensures
rapid heat-up and stable temperature control.

• PLA, PETG, TPU, ABS & ASA
• Nylon & High-Temperature Materials
• Carbon Fiber Reinforced Filaments
• Stable High-Speed Extrusion

Intelligent Segmented Heatbed

Efficient Heating. Faster Preparation.

The intelligent segmented heated bed divides the platform into independently controlled
heating zones. Users can activate only the required print area, reducing power consumption
and shortening heating times.

• Faster Bed Heating
• Reduced Energy Consumption
• Uniform Heat Distribution
• Better First Layer Adhesion
• Optimized for Small and Large Prints

121-Point Auto Bed Leveling

Perfect First Layers Every Time

The Neptune 4 Pro features a 121-point automatic bed leveling system that scans the
surface and compensates for minor variations automatically. Manual auxiliary leveling
knobs are also included for fine adjustment.

• Automatic Surface Compensation
• Reliable First Layer Success
• Reduced Manual Calibration
• Improved Print Consistency
• Beginner-Friendly Operation

Efficient & Instant Cooling System

Rapid Cooling for Better Print Quality

The Neptune 4 Pro uses 4 × 4020 ball bearing blower fans and 2 × double-sided
4015 model cooling fans to rapidly cool freshly deposited filament for cleaner details,
stronger bridges, and reduced warping.

• Sharper Details
• Improved Overhangs
• Better Bridging Performance
• Reduced Warping
• Enhanced High-Speed Print Quality
