Product Description:
The ELEGOO Neptune 4 Max is a high-performance FDM 3D printer designed for large-format printing, exceptional speed, and reliable precision. Equipped with pre-installed Klipper firmware, it delivers fast printing with maximum speeds up to 500 mm/s and high acceleration for efficient workflows. Featuring a massive 420 × 420 × 480 mm build volume, this printer allows you to create large models or multiple smaller parts in a single job, making it ideal for professional prototyping, engineering designs, cosplay, functional parts, and large-scale projects. 

The Neptune 4 Max includes a robust dual-gear direct drive extruder for powerful and smooth filament feeding, and a high-temperature capable hotend that reaches up to 300 °C, expanding your material options across PLA, PETG, TPU, ABS, ASA, and more. An advanced automatic bed leveling system with 121-point calibration ensures stable first layers, while accelerometers and Klipper optimizations like input shaping and pressure advance enhance print quality even at high speeds. 

Connectivity options like Wi-Fi, LAN, and USB give flexible control over your printing workflow, and features such as filament run-out detection and power-loss recovery increase reliability for long or unattended prints. With its large build area and powerful hardware, the Neptune 4 Max is built to handle ambitious prints for makers, educators, and small businesses alike.
