Original description
The Elegoo Neptune 4 Plus stands out as a next-generation high-speed 3D printer built for creators who need professional-grade performance without the premium price tag. Combining advanced Klipper-based control, a large build area, and exceptional structural stability, it is engineered to meet the needs of rapid prototyping, production runs, artistic creation, and functional engineering applications.
Unmatched Printing Speed Powered by Klipper
At the heart of the Neptune 4 Plus is the Klipper firmware, a highly optimized system designed to deliver remarkable printing speeds—up to 500mm/s—while maintaining high accuracy. With advanced features such as Input Shaping and Pressure Advance, the printer dramatically reduces vibrations and ensures sharp corners, smooth curves, and clean surfaces even at high speeds.
This makes it ideal for users who value time efficiency, especially in commercial environments or workshops that require rapid production.
Large Build Volume for Massive Creativity
The spacious 320×320×400mm build volume allows you to print big models like cosplay helmets, RC body shells, engineering prototypes, and architectural models. It also enables batch printing of multiple smaller items, making it suitable for small businesses and production-focused creators.
Direct Drive Extrusion for Better Filament Handling
The dual-gear direct drive extruder provides precise and consistent extrusion. Flexible materials like TPU print effortlessly, while stiff materials such as ABS and PETG benefit from stable feeding. The all-metal hotend opens the door for high-temperature filaments, expanding your creative potential.
Superior Bed Adhesion & Easy Print Removal
A PEI-coated magnetic flexible plate ensures strong adhesion during printing and quick, hassle-free part removal once the print is finished. The plate’s durability and excellent thermal distribution contribute to consistent print quality.
Automatic Bed Leveling + Manual Compensation
With 36-point auto bed leveling, the printer guarantees a perfectly calibrated print surface every time. You can fine-tune using manual Z-offset adjustments, ensuring flawless first layers.
Stronger Cooling, Stronger Results
High-speed printing requires effective cooling, and the Neptune 4 Plus delivers with:
- A large 360° high-speed fan system
- Dedicated part-cooling fans
- Efficient airflow channeling
This results in sharper details, reduced stringing, and better overhang performance even at high speeds.
Rigid Frame for Industrial-Level Stability
The strengthened Z-axis with dual lead screws and durable metal frame ensures minimal wobbling and excellent layer consistency. Whether you're printing tall objects or intricate mechanical parts, the structural rigidity supports precision.
User-Friendly Experience
The 4.3-inch touchscreen, intuitive UI, post-print recovery features, and silent drivers make the Neptune 4 Plus enjoyable for beginners, professionals, and businesses alike. The printer also includes power-loss recovery, filament runout detection, and quick-assembly design.
A True All-Round Performer
From fast prototyping to functional production, the Elegoo Neptune 4 Plus stands tall as a reliable, powerful, and budget-friendly machine that outperforms many printers in its category.
