3D printer Elegoo Neptune 4 Plus — build volume 300×300×350 mm

Elegoo Neptune 4 Plus 3D Printer combines a large build volume with precise and fast FDM printing. The printer is designed for medium to large parts and supports common filament materials. It offers an accurate extrusion system, heated bed and high-temperature nozzle, making it suitable for prototyping, functional parts and detailed hobby models.

Advantages

The Neptune 4 Plus provides a maximum build volume of 320 × 320 × 385 mm and printing precision of ±0.1 mm with a 0.4 mm nozzle. Print speeds range from 30 to 500 mm/s with a typical speed around 250 mm/s and maximum acceleration up to 12,000 mm/s². A maximum nozzle temperature of 300°C and heated bed up to 110°C expand material compatibility. The device supports Cura software, accepts STL and OBJ files and outputs G-code; data transfer is possible via USB drive or LAN. The printer is compact for its class (578 × 533 × 640 mm) and weighs 14.4 kg.

Suitable for

• Prototyping and functional part production
• Hobby models and detailed miniatures
• Small workshops and makerspaces requiring larger build volume
• Educational use for teaching FDM printing

How to use

Prepare your 3D model in a compatible editor and export it as an STL or OBJ file. Slice the model in Cura and generate G-code with appropriate temperature and speed settings for the chosen filament. Transfer the G-code to the printer via USB drive or network, preheat the nozzle and bed to the recommended temperatures, level the build plate if necessary, and start the print. Monitor the first layers to confirm adhesion and make adjustments to bed leveling or print settings if needed.

Usage recommendations

For reliable results, use quality filaments with recommended printing temperatures, ensure the build plate is level and clean before each print, and allow the nozzle and bed to reach stable temperatures. For larger prints, consider enabling part cooling and using appropriate infill and support settings in Cura to balance strength and print time.
