Elegoo Neptune 4 Max

Elegoo Neptune 4 Max

The Elegoo Neptune 4 Max is built for one specific purpose — printing big, printing fast, and printing reliably without a five-figure budget. It redefines what large format means under ₹50,000, bringing Klipper firmware, CoreXY motion, and a build volume that eliminates the need to split most large models into multiple parts.

Key Specs:

• Build Volume: 420 × 420 × 480 mm — one of the largest in its class
• Max Print Speed: 500 mm/s (default 250 mm/s recommended for quality)
• Acceleration: Up to 8,000 mm/s²
• Firmware: Klipper — pre-installed with input shaping and pressure advance
• Processor: ARM 64-bit 1.5GHz quad-core — onboard storage 8GB
• Extruder: Direct drive dual-gear, 5.2:1 gear ratio
• Nozzle: 300°C high-temp nozzle — extended hotend design
• Bed Temperature: 85°C max
• Auto Bed Levelling: 11 × 11 point (121 points)
• Frame: Open frame — aluminium extrusion
• Filament compatibility: PLA, PETG, TPU, ABS, ASA, Nylon
• Connectivity: Wi-Fi, LAN, USB

Who it’s for:

• Makers, product designers, and small manufacturers who need large-format output for PLA and PETG applications — cosplay, architecture, large prototypes, batch production of medium-sized parts, and any application where splitting a model is the only current alternative. Also ideal as a workhorse machine for print farms focused on volume over material diversity.
