Elegoo Neptune 2 Review: A Budget 3D Printing Powerhouse with Room to Grow

The world of 3D printing has become increasingly accessible, with budget-friendly options offering impressive capabilities. One such contender is the Elegoo Neptune 2, a printer that has garnered attention for its compelling combination of features and affordability. As a tech enthusiast always on the lookout for innovative and value-driven products, I took a deep dive into the Elegoo Neptune 2 to see if it lives up to the hype.

Unpacking the Elegoo Neptune 2: A User-Friendly Assembly Experience

The Elegoo Neptune 2 arrives semi-assembled, requiring a bit of DIY spirit to get up and running. However, don’t let this deter you – the assembly process is surprisingly straightforward, even for those new to 3D printer construction. Elegoo provides a comprehensive user manual with clear illustrations and diagrams, guiding you through each step. Additionally, a microSD card included with the printer provides a handy video tutorial (though be warned, the accompanying music might be a bit much for some).

Most of the sub-modules, such as the Z motor and extruder, come pre-assembled, making the process feel more like a rewarding puzzle than a daunting task. The included toolset, complete with Allen keys, screwdrivers, and even zip-ties for cable management, demonstrates Elegoo’s attention to detail.

While the assembly is generally smooth, there are a couple of points to be aware of. Firstly, the voltage switch on the power supply might be set to 230V instead of the standard 115V used in the US. It’s a quick fix, but something to double-check before powering on the printer. Secondly, the V-slot rollers might require tension adjustment, as they were quite loose on my unit.

Design and Features: A Blend of Familiar and Innovative

The Elegoo Neptune 2 shares a similar design language with the popular Creality Ender 3 Pro, featuring a sturdy aluminum extrusion frame with a rear-mounted power supply. However, Elegoo introduces some noteworthy design choices. The smooth, matte black finish on the front-facing surfaces gives the Neptune 2 a sleek and professional aesthetic, setting it apart from the more utilitarian look of some competitors.

One standout feature is the filament run-out sensor integrated directly into the extruder module. This clever design uses a mechanical switch to detect filament presence, automatically pausing the print if the filament runs out. It’s a valuable addition, especially for lengthy prints, saving you from wasted time and material.

User Interface: Functional but Could Use Refinement

The Neptune 2 relies solely on a 3.5-inch color touchscreen for user interaction. While responsive, the dark UI can be difficult to read, especially when the build platform is positioned over it during printing. The menu structure is also a bit clunky and could benefit from simplification.

Leveling the Playing Field: Manual Leveling with Potential for Automation

The Elegoo Neptune 2 utilizes a manual bed leveling process similar to the Ender 3 Pro. While not overly complicated, it can be a tad tedious, involving adjusting thumbscrews to achieve a level print surface. The good news is that the Neptune 2’s controller board supports a BLTouch sensor, an auto-leveling solution that can significantly streamline this process. The extruder gantry even has pre-drilled holes for mounting the sensor, making it a worthwhile upgrade for those seeking greater convenience.

Build Platform: A Unique Approach with Room for Improvement

Elegoo opted for an interesting build platform design with the Neptune 2. It falls somewhere between the flexible magnetic bed of the Ender 3 Pro and the solid glass platform of the Ender 3 V2. The Neptune 2’s platform consists of a rigid fiberglass board with a textured mat adhered to the top.

While this design offers decent adhesion and part removal, I did encounter some minor issues. The textured mat showed signs of bubbling after a few prints, potentially impacting the surface finish of larger, flatter models. A more durable solution, perhaps a flexible PEI sheet, might have been a better choice.

Printing Performance: Surprisingly Capable for the Price

Despite its budget-friendly price tag, the Elegoo Neptune 2 delivers surprisingly impressive print quality. Using the included Elegoo Cura slicing software, I put the printer through its paces with a variety of models and settings.

Elegoo Cura: A User-Friendly Slicing Solution

Elegoo Cura is a customized version of the popular Cura slicing software, offering a streamlined experience tailored for the Neptune 2. It caters to users of all skill levels, with a Basic mode for beginners and an Expert mode for seasoned tinkerers.

One of the standout features of Elegoo Cura is the detailed time report it provides for each sliced model. This breakdown goes beyond simply stating the print time, offering insights into where the printer spends the most time, such as infill, walls, or support structures. This information can be invaluable for optimizing print settings and reducing overall print time.

Modifications and Upgrades: Unleashing the Neptune 2’s Potential

The Elegoo Neptune 2’s open-source nature and readily available modification options make it a tinkerer’s dream. The ability to add a BLTouch sensor, a second extruder, or even a laser engraver module opens up a world of possibilities beyond standard 3D printing. This makes the Neptune 2 an excellent platform for experimentation and pushing the boundaries of what’s possible with a budget-friendly machine.

Final Verdict: A Budget-Friendly Contender with Trade-offs

The Elegoo Neptune 2 is a compelling option for budget-conscious makers and hobbyists seeking a capable and upgradable 3D printer. Its impressive print quality, user-friendly software, and potential for modification make it a strong contender in its price range.

However, it’s not without its drawbacks. The manual bed leveling, potentially fragile build platform, and somewhat clunky user interface might deter those seeking a more polished out-of-the-box experience.

Should You Buy the Elegoo Neptune 2?

• Yes, if you’re on a tight budget and prioritize print quality, upgradability, and don’t mind a bit of tinkering.
• Maybe, if you’re new to 3D printing and are comfortable with some assembly and troubleshooting.
• Consider alternatives, if you prioritize ease of use, a refined user experience, and a more robust build platform.
