Neptune 4 Max FDM Filament 3D Printer

Massive build volume, high-speed Klipper performance, and powerful extrusion for large-scale 3D printing.

The ELEGOO Neptune 4 Max is a large-format FDM 3D printer designed for creators who want to produce bigger models, multiple parts, prototypes, and functional components in a single print. With an impressive 420 × 420 × 480 mm build volume, speeds of up to 500 mm/s, Klipper firmware, automatic bed leveling, and a 300°C high-temperature nozzle, the Neptune 4 Max combines size, speed, and versatility in one powerful machine.

Key Features

• Massive 420 × 420 × 480 mm Build Volume: Create large models or print multiple smaller objects simultaneously with plenty of workspace.
• 500 mm/s Maximum Printing Speed: High-speed printing helps reduce production time, with a recommended/default speed of 250 mm/s.
• Klipper Firmware: The built-in Klipper system and ARM 64-bit quad-core processor support fast printing and advanced functions such as Input Shaping and Pressure Advance.
• Up to 8,000 mm/s² Acceleration: Designed for efficient high-speed movement while maintaining stable printing performance.
• 121-Point Auto Bed Leveling: An 11 × 11 leveling grid automatically compensates for variations across the print surface.
• 300°C High-Temperature Nozzle: The 60W ceramic heating system supports materials including PLA, PETG, TPU, ABS, ASA, and Nylon.
• Dual-Gear Direct Extruder: A 5.2:1 reduction ratio provides smooth and reliable filament feeding during printing.
• Advanced Cooling System: Multiple cooling fans rapidly cool newly deposited layers, helping improve print quality during high-speed printing.
• Input Shaping & Pressure Advance: Klipper's advanced features help reduce vibration-related artifacts, filament ooze, and blobbing.
• Automatic Resonance Compensation: X- and Y-axis acceleration sensors help automatically calibrate resonance compensation parameters.
• Dual-Sided Build Plate: A specialized PLA surface provides strong adhesion with reduced warping, while the textured PEI surface offers strong adhesion and easier model removal.
• Stable Z-Axis Design: Dual lead screws, dual motors, and double tie rods provide stable and precise vertical movement.
• Powerful Connectivity: Transfer files through Wi-Fi, USB, or LAN/WLAN, with support for web-based remote control and network printing.
• OTA Firmware Updates: Keep the printer updated with new features and performance improvements through over-the-air firmware updates.
• Filament Detection: Helps detect filament runout or breakage and pause the printing process.

Built for Large-Scale Printing

The Neptune 4 Max's 420 × 420 × 480 mm build volume gives you the freedom to create substantially larger objects than a typical desktop 3D printer. It can also accommodate multiple smaller models in a single print, making it useful for prototypes, large models, functional components, educational projects, and creative designs.

High-Speed Klipper Performance

The Neptune 4 Max comes with pre-installed Klipper firmware and an ARM 64-bit 1.5 GHz quad-core processor. It can reach speeds of up to 500 mm/s with acceleration up to 8,000 mm/s². Klipper features such as Input Shaping and Pressure Advance are designed to improve print quality and reduce unwanted artifacts during high-speed printing.

Powerful Extrusion & High-Temperature Printing

The dual-gear direct extruder provides consistent filament feeding, while the 60W ceramic heating element and 300°C hot end allow the Neptune 4 Max to work with a broad range of materials. ELEGOO lists compatibility with PLA, PETG, TPU, ABS, ASA, and Nylon. For ABS and ASA, ELEGOO recommends using an appropriate enclosure.
