3D printer Elegoo Neptune 4 Max — large build volume, high precision

Elegoo Neptune 4 Max 3D Printer combines a large build volume with high precision and speed, designed for printing sizable, detailed models in one run. The FDM printer supports common file formats and standard slicing software, and its robust frame and heated bed enable stable, repeatable results for engineering, architectural and creative applications.

Advantages

The Neptune 4 Max offers a maximum build volume of 420 × 420 × 480 mm, printing precision of ±0.1 mm and a 0.4 mm nozzle for accurate detail reproduction. It supports print speeds from 30 to 500 mm/s (typical 250 mm/s) and maximum acceleration up to 8,000 mm/s², enabling efficient production of large parts. The machine accepts a wide range of materials thanks to a maximum nozzle temperature of 300°C and a heated bed reaching 85°C (at 25°C ambient). USB and LAN interfaces simplify file transfer and remote control, while Cura compatibility and STL/OBJ input make workflow straightforward.

Suitable for

• Large prototypes and functional parts
• Architectural and engineering models
• Artistic sculptures and large-scale hobby models
• Small workshops and prototyping labs

How to use

Prepare a 3D model in STL or OBJ format and slice it in Cura to generate G-code. Transfer the G-code to the printer via USB drive or over the LAN connection. Set material-specific temperatures (nozzle up to 300°C, heated bed up to 85°C) and choose an appropriate print speed; for large, detailed parts use moderate speeds and the specified 0.4 mm nozzle. Ensure the build plate is level and the filament is loaded correctly before starting the print. Monitor initial layers to confirm adhesion and dimensional accuracy.

Usage recommendations

For consistent results with large prints, use a stable workspace within the recommended ambient temperature range (5°C–40°C), calibrate the bed before long prints, and select filament profiles in Cura that match the nozzle and bed temperature limits. When printing engineering materials or high-temperature filaments, verify material compatibility and ventilation requirements.
