Elegoo Neptune 4 Plus 3D Printer Review: Advanced Printing at an Affordable Price

Unboxing and Assembly Experience

Upon arrival, the Neptune 4 Plus comes well-equipped with tools and accessories for setup, including a USB cable, zip-ties, and Allen keys. Pre-assembled components like motors and wiring harnesses simplify the assembly process, making the printer almost ready to use straight out of the box. The stabilizing rods, running from the top of the Z-axis frame to the base, add stability during printing, especially for taller prints. Although assembly is not overly complex, an extra pair of hands can make the process smoother.

Design and Build Quality

At a glance, the Neptune 4 Plus resembles its predecessor, the Neptune 3 Plus, but closer inspection reveals key differences, like the new part cooling fan assembly mounted to the rear of the X-axis. The dual lead screws with a synchronizing belt on the Z-axis and additional stabilizing bars ensure stability for tall prints, with a maximum build height of 385mm. The printer's aesthetic, including the "CREATE THE FUTURE" slogan on the aluminum extrusions, is distinct and may appeal to some users more than others.

Sensorless Homing and Heating System

The Neptune 4 Plus features sensorless homing, eliminating traditional endstops on the axes. While this innovative approach has led to some reports of a grinding noise during homing, adjustments to the homing speed in the firmware can resolve this issue. Unlike its smaller counterpart, the Neptune 4 Plus heats the entire platform for each print, reaching up to 110C in under a minute thanks to its powerful 400W power supply.

User Interface and Control

The primary user interface is a 4.3-inch color LCD touchscreen, reminiscent of early PDAs, offering a satisfying and intuitive user experience. The interface is clean and user-friendly, with options for Klipper acceleration calibration and PID tuning for the hot end directly from the menu. This functionality is particularly beneficial for users seeking advanced control without relying on command line prompts.

Integrated Wi-Fi Capabilities

The Neptune 4 Plus includes integrated Wi-Fi, enhancing the printing experience with remote start, monitoring, and more. The machine features a terminal for the included Wi-Fi antenna, which is easily attached using the provided hex wrench, offering a seamless connection for wireless printing.

Conclusion: Elegoo Neptune 4 Plus as a Versatile and Advanced 3D Printer

The Elegoo Neptune 4 Plus stands out as a versatile and advanced 3D printer that brings a new level of performance and features to the budget-friendly segment. Its design, stability features, sensorless homing, rapid heating system, user-friendly interface, and Wi-Fi capabilities make it an excellent choice for both beginners and experienced users. As a mid-range option in the Neptune series, it offers a perfect balance of size, speed, and price, cementing its place among the best desktop 3D printers available today.
