What customers say
The Elegoo Neptune 4 Pro is highly regarded for its exceptional speed and value, largely due to the preinstalled Klipper firmware enabling rapid printing right away. Users appreciate the robust metal build and the effective dual-gear direct drive extruder, which produces high quality results after calibration. This machine democratizes high speed FDM printing at a competitive price. A few initial firmware bugs required updates for resolution. The primary drawback noted is the increased operational noise resulting from the powerful cooling system needed for fast performance. While generally excellent, achieving perfect first layers sometimes requires minor manual adjustments beyond the auto leveling feature.
Know before you buy
These units are pre-owned returns, meaning their condition ranges from open-box to units requiring repair. You should be prepared to perform basic maintenance or troubleshooting depending on the specific condition grade you select.
The printer is compatible with standard 1.75 mm filaments, including PLA, ABS, PETG, and TPU. This versatility allows you to experiment with both rigid and flexible materials for various projects.
While the Neptune 4 Pro features an intuitive touchscreen and straightforward assembly, buying a pre-owned unit may require some mechanical aptitude. You should be comfortable with basic calibration and potentially replacing minor components if you purchase a unit listed as damaged for fix-up.
The PEI coating provides excellent adhesion for your prints while they are hot, and allows for easy removal once the plate cools down. It is a durable surface that reduces the need for adhesives and simplifies the post-printing cleanup.
Every purchase includes lifetime customer support from Elegoo. Whether you need help with initial setup or troubleshooting a specific print issue, their team is available to assist you throughout the life of the machine.
The printer comes with a warranty of up to one year, but this coverage varies by component. Please note that consumable parts, such as nozzles or build plates, have limited or no warranty coverage.
