Usage Tips and Best Practices

To get the most out of your Elegoo Neptune 3 Plus, consider these tips:

Leveling is Key: While the Neptune 3 Plus features auto bed leveling, performing a manual adjustment afterward is always recommended, especially for large prints. Use the paper method to fine-tune the Z-offset after auto-leveling.
Adhesion is Crucial: For filaments like ABS, use a brim or raft to improve bed adhesion and prevent warping. Ensure the bed is clean using isopropyl alcohol before each print.
Temperature Tuning: Experiment with nozzle and bed temperatures to find the optimal settings for each filament type. Too low, and you might have adhesion issues. Too high, and you could see stringing or warping.
Speed Management: While the printer can handle speeds up to 180 mm/s, slower speeds (60-80 mm/s) usually result in better print quality, especially for intricate designs.
Filament Storage: Store your filaments in airtight containers with desiccant packs to prevent moisture absorption, which can lead to printing issues.
Regular Maintenance: Clean the nozzle regularly to prevent clogging. Lubricate the Z-axis lead screws to ensure smooth movement.
First Layer: Start by printing slow on your first layer. Slower speed will allow the filament to stick better to the bed.

Breakdown of Ratings

Here’s a rating breakdown, out of 10, across key performance areas:

Print Quality: 8.5 – Capable of producing detailed and smooth prints with proper settings.
Build Volume: 9 – The large build volume is a major selling point, allowing for larger and more complex prints.
Printing Speed: 8 – While it can reach higher speeds, optimal quality is achieved at moderate speeds.
Material Compatibility: 8 – Handles a wide range of materials, but ABS can require more tuning.
Bed Adhesion & Leveling: 8.5 – Auto bed leveling is convenient, but manual adjustment is sometimes necessary.
Reliability: 8 – Generally reliable, but occasional maintenance is required.
Ease of Use: 8.5 – User-friendly touchscreen interface and straightforward setup process.
Firmware and Software: 7.5 – Stock firmware is functional but could benefit from further updates and customization options.
Connectivity Options: 7 – Standard USB and SD card connectivity are adequate, but Wi-Fi would be a welcome addition.
Build Quality & Durability: 8 – Sturdy aluminum frame provides a solid foundation.
Noise Level: 7 – Average noise level; not the quietest printer on the market.
Maintenance Requirements: 7.5 – Requires regular cleaning and lubrication.
Customer Support: 7 – Community support is active, but direct support can sometimes be slow.
Upgradeability: 8 – Plenty of upgrade options available, such as improved cooling or a different extruder.
Price to Performance Ratio: 9 – Excellent value for the features and build volume offered.
