The ELEGOO Neptune 4 Plus is built for speed, size, and precision, powered by pre-installed Klipper firmware on a 64-bit quad-core ARM processor. It delivers print speeds up to 500 mm per second with acceleration up to 12,000 mm per second squared, supported by input shaping, pressure advance, and acceleration sensors for smooth, high-quality results. With a large build volume of 320 by 320 by 385 mm, a dual-gear direct drive extruder, and a high-temperature nozzle capable of reaching 300 degrees Celsius, the Neptune 4 Plus is ready to print with a wide range of materials including PLA, PETG, TPU, ABS, ASA, and nylon. Features like 121-point auto bed leveling, a segmented heated bed, a magnetic PEI build surface, and dual Z-axis lead screws provide excellent stability and layer consistency. A powerful multi-fan cooling system prevents warping, while Wi-Fi, USB, and LAN options offer flexible connectivity. The printer also includes sensors for filament runout and power loss recovery, along with a removable 4.3 inch touchscreen and low-noise operation. The Neptune 4 Plus is a reliable, high-performance choice for creators needing large-format prints without sacrificing speed or detail.
