Our take on the Elegoo Neptune 4 Plus-E 3D Printer

The Elegoo Neptune 4 Plus is an open-frame FDM printer with a 320 x 320 x 385 mm build volume, a direct-drive extruder and a PEI heated bed. It runs fast, with a rated 500 mm/s print speed, and handles high nozzle and bed temperatures that suit PLA and other common filaments. Auto and auxiliary bed leveling plus a touchscreen keep setup simple for hobbyists moving up from a smaller printer. It competes with other large-format bedslingers on build size and speed rather than on an enclosed chamber, which it lacks.

Questions and answers

What can I print with the Neptune 4 Plus?
Its 320 x 320 x 385 mm volume suits large single-piece models, prototypes and functional parts. PLA is the listed supported material, and the 300 C hotend and 85 C bed leave headroom for other common filaments.
Does it level the bed automatically?
Yes. It uses auto bed leveling plus auxiliary leveling, so you do not adjust the bed by hand for every print.
Is it enclosed?
No. It is an open-frame printer, so drafts and room temperature affect prints and it is not ideal for materials that need a heated chamber.
How do I connect to it?
It has Wi-Fi and USB inputs and a touchscreen for on-machine control.
What nozzle and filament does it use?
It ships with a 0.4 mm nozzle and takes 1.75 mm filament through a direct-drive extruder.
Is it good for beginners?
It is approachable thanks to auto leveling and the touchscreen, but its size and speed mean tuning takes some patience. A smaller printer is easier to start on.
