Pre-installed Klipper firmware for high-speed printing
The Neptune 4 Plus comes pre-installed with Klipper firmware and an ARM 64-bit 1.5 GHz quad-core processor for fast command processing. This enables print speeds of up to 500 mm/s (standard 250 mm/s) with accelerations of up to 12000 mm/s², delivering fast and efficient prints. Advanced features such as input shaping and pressure advance help reduce issues such as filament ooze and artifacts, while acceleration sensors on the X and Y axes ensure automatic calibration for improved print quality.
Clips high-speed motherboard for improved performance
With its Klipper motherboard and powerful ARM processor, the Neptune 4 Plus ensures smooth and stable high-speed printing. The 8GB ROM provides plenty of storage space for large print files, and the system is optimized for minimal vibration, further improving print quality. The printer automatically compensates for resonance, resulting in accurate prints every time.
Massive space for your creations
The Neptune 4 Plus has a generous build volume of 320 x 320 x 385 mm (12.59 x 12.59 x 15.15 inches), making it perfect for larger models or printing multiple parts. Whether you're working on a large project or printing several smaller items at once, this spacious printer lets you expand your creative possibilities.
300°C high-temperature nozzle for versatile filament options
Neptune 4 Plus is equipped with a 300°C high-temperature nozzle and can print a wide range of filaments, including nylon. The extended hotend features a 60W ceramic heating element and a brass heating block, ensuring consistent and stable temperature control for optimal print performance. Automatic calibration of the nozzle PID parameters ensures that the nozzle remains at the perfect temperature throughout the print, preventing fluctuations that can affect print quality.
Powerful extruder and upgraded hotend for smooth printing
The Neptune 4 Plus features a dual-gear direct extruder with a 5.2:1 reduction ratio, providing reliable and smooth filament extrusion. It weighs just 290g, reducing weight while maintaining performance. The titanium alloy throat tube allows for efficient heat dissipation and minimizes nozzle clogging. The upgraded hotend is designed to handle high temperatures, allowing you to print with materials such as PLA, PETG, ABS, ASA, TPU, and high-temperature nylon.
Versatile connectivity and control
Neptune 4 Plus offers multiple connectivity options including WIFI, USB and LAN transfer, allowing you to manage your prints seamlessly. You can easily control the printer remotely via the web interface, and network printing from multiple machines allows you to handle multiple jobs at once. Start printing with just one click and enjoy the convenience of wireless file transfer.
