Elegoo Neptune 4 Max 3D Printer

The Elegoo Neptune 4 Max stands as one of the most capable consumer-grade large-format 3D printers on the market, offering unmatched value for creators who need both size and speed. Whether you're building massive cosplay props, architectural displays, engineering prototypes, or multiple production parts at once, the Neptune 4 Max provides outstanding performance driven by advanced firmware, precision hardware, and a highly robust structure.

A Truly Massive Build Volume

With an impressive 420 × 420 × 480 mm print capacity, the Neptune 4 Max unlocks large-scale creativity. This expansive workspace lets you print:

• Full helmet-size cosplay models
• Extra-large prototyping parts
• Furniture accessories
• RC and drone parts
• Batch production items
• Detailed architectural models

Instead of slicing projects into smaller sections, you can now print them in one go—saving time, effort, and improving structural integrity.

Blazing Fast Performance with Klipper

Speed is where the Neptune 4 Max truly shines. Utilizing a Klipper-based motion control system, it achieves incredible printing speeds:

• Up to 500mm/s maximum speed
• 12,000mm/s² acceleration
• Built-in Input Shaping and Pressure Advance

This ensures:

• Reduced ringing
• Sharper edges
• Smoother curves
• Cleaner details

Printing large models no longer means waiting multiple days—now professionals and businesses can complete projects in hours.

Direct Drive Extrusion for Reliable Filament Control

The machine features a dual-gear direct drive extruder, which ensures consistent material flow and excellent handling of flexible filaments like TPU. Combined with an all-metal high-flow hotend, the printer can handle higher temperature materials and maintain extrusion stability even during long print sessions.

High-Precision Bed Leveling

To support the massive print surface, the Neptune 4 Max includes a 49-point automatic bed leveling system. This ensures perfect first layers across large projects, reducing print failures and improving accuracy.

Users can also adjust Z-offset for fine-tuning.

PEI Magnetic Flexible Plate

Printing on a large surface is often challenging, but the PEI-coated plate ensures:

• Strong adhesion
• Warp resistance
• Effortless part removal

Just flex the plate, and the print pops off easily—no tools required.

Superior Cooling System

High-speed printing generates heat and demands high-efficiency cooling. The Neptune 4 Max incorporates:

• High-pressure part cooling fans
• Dedicated hotend cooling
• 360° airflow design

This gives cleaner overhangs, reduced stringing, and extremely crisp details even at high speed.

Rigid Metal Frame & Stable Z-Axis

Large printers require exceptional stability. Elegoo delivers with:

• Hardened metal frame
• Dual Z-axis + dual motors
• Anti-backlash system
• Thickened support rods

The result: smooth vertical movement, minimized wobble, and consistent layer stacking even with tall prints.

Smart Features for Modern Makers

The Neptune 4 Max includes features that make printing easier and safer:

• Filament runout sensor
• Power-loss recovery
• 4.3-inch color touchscreen
• Silent stepper drivers
• Quick assembly design

These conveniences ensure that long, complex prints run efficiently and reliably.
