Key Features

Pre-installed Klipper Firmware

Neptune 4 Plus ships with Klipper, enabling speeds up to 500 mm/s (default 250 mm/s) and up to 12,000 mm/s² acceleration, with advanced features including input shaping and pressure advance calibration. Built-in acceleration sensors on X and Y axes handle automatic calibration for cleaner, crisper prints.

Klipper High-Speed Motherboard

Klipper mainboard + ARM 64-bit 1.5 GHz quad-core processor deliver the compute headroom for high-speed printing. 8 GB ROM provides ample storage for your print files. Input shaping and pressure advance reduce artifacts, ooze, and blobbing.

Massive Space for Your Creations

A generous 320 × 320 × 385 mm build volume lets you print larger models—or batch multiple parts—in a single job to boost productivity.

300 °C High-Temp Nozzle

Extended hotend with 60 W ceramic heater and brass block reaches 300 °C for materials like nylon. Automatic PID calibration keeps temperature stable for consistent results.

Powerful Extruder & Upgraded Hotend

5.2:1 dual-gear direct extruder (290 g) delivers reliable flow; all-titanium throat improves heat dissipation and reduces clogs. 60 W heater + brass block melt filament quickly even at speed. Supports PLA, PETG, ABS, ASA, TPU, and nylon.

Versatile Connectivity & Control

Connect via Wi-Fi, USB flash drive, or LAN. Enjoy web remote control, multi-printer networking, and one-click file transfer for streamlined workflows.

Efficient Cooling System

High-flow part cooling ensures strong overhangs and crisp details at speed.

PEI Magnetic Platform

Excellent adhesion during printing and easy, tool-less part release.

Reliable & Quiet Printing

Refined motion system and drivers reduce noise while maintaining accuracy.
