In-Depth Review of the Neptune 4 Max 3D Printer

Speed that Saves Time

The standout feature of the ELEGOO Neptune 4 Max is undoubtedly its speed. The printer’s maximum speed of 500mm/s is exceptional, cutting down print times significantly. For those who have dealt with slow prints, this upgrade is a game-changer. The Klipper firmware allows for both rapid printing and smooth acceleration up to 8000mm/s², making the process quick without sacrificing quality.

Generous Build Volume

A spacious 16.53”x16.53”x18.89” (420x420x480mm) build area means that large projects are no problem. This size opens up opportunities to print larger models or multiple items simultaneously. You can even venture into complex designs that typically wouldn’t fit on a smaller build plate, making it perfect for enthusiasts looking to tackle bigger projects.

Superior Print Quality

Despite the high-speed capability, the Neptune 4 Max doesn’t compromise on print quality. The X and Y axes come equipped with acceleration sensors, allowing for automatic calibration that reduces vibrations and maintains precision. This leads to detailed prints with smooth layers and accurate dimensions. Whether it’s a highly detailed miniature or a large-scale part, the Neptune 4 Max handles it all.

Versatility in Filament Use

The printer supports a wide range of materials such as PLA, PETG, ABS, TPU, and even Nylon, thanks to its 300°C high-temperature nozzle. This makes it versatile for various project needs, whether it’s a durable functional part or a flexible model. The self-developed dual-gear direct drive extruder ensures smooth filament feeding, reducing the risk of clogs or jams.

Auto-Leveling Simplifies Setup

Auto-leveling is an essential feature for hassle-free 3D printing, and the Neptune 4 Max handles it well. With sensors on the X and Y axes, the printer automatically adjusts itself to ensure a perfectly level bed. This not only improves print quality but also minimizes errors that could otherwise occur due to uneven surfaces.

Drawbacks to Consider

One potential downside is the assembly process. Given the large size and somewhat heavy components, you might need assistance putting the printer together. Additionally, since the machine is designed for high performance, the nozzle might require monthly changes to prevent clogs, especially if used daily. However, these cons are outweighed by the machine’s reliability and impressive performance.

Who Will Love the Neptune 4 Max?

  • Hobbyists and Professionals looking for a quick, reliable 3D printer with a large build volume.
  • Makers of Big Designs that need ample space for printing large models or multiple smaller items.
  • Multi-Material Users who want to experiment with different filaments like PLA, PETG, ABS, and more.
  • Efficient Workers who appreciate reduced print times and automated bed leveling for faster workflows.

Who Might Look Elsewhere?

  • Solo Set-Up Users who don’t have an extra set of hands for assembly might find the setup process a bit challenging.
