Featuring a huge 420 × 420 × 480 mm build volume, Klipper-powered performance, and a robust direct-drive extrusion system, the Neptune 4 Max enables users to print large functional parts, full-size helmets, props, architectural models, and production components in a single piece.
Combining one of the largest build volumes in its class with modern high-speed printing technology, the Neptune 4 Max delivers professional-level capabilities while remaining accessible to hobbyists and professionals alike. :contentReference[oaicite:1]{index=1}
Key Benefits
Huge 420 × 420 × 480 mm Build Volume – Create oversized prototypes, cosplay armour, helmets, signage, furniture components, moulds, and production parts without splitting models into multiple sections.
Klipper-Powered High-Speed Printing – Pre-installed Klipper firmware enables print speeds of up to 500 mm/s with accelerations up to 8,000 mm/s², significantly reducing production times compared to traditional FDM printers.
300°C High-Temperature Hotend – The upgraded hotend features a 60W ceramic heating element, extended melt zone, and titanium alloy heat break, allowing reliable printing of advanced materials including Nylon, ABS, ASA, PETG, TPU, and PLA.
Dual-Gear Direct Drive Extruder – The lightweight 5.2:1 reduction-ratio dual-gear extruder provides smooth, consistent filament feeding and excellent control, particularly when printing flexible and engineering-grade materials.
121-Point Automatic Bed Levelling – Advanced mesh bed levelling automatically compensates for surface variations across the large build platform, helping ensure reliable first layers and improved print consistency.
Intelligent Zoned Heated Bed – Independent heating zones improve energy efficiency and heating performance by allowing only the required print area to be heated when printing smaller models.
Enhanced Cooling & Motion Control – Multiple high-performance cooling fans, input shaping, pressure advance, and integrated accelerometers help maintain print quality during high-speed operation.
