ELEGOO Extruder for Neptune 4 Plus/Max 3D Printer, Fully Assemble Dual-Gear Direct Drive Extruder, ELEGOO Official 3D Printer Accessories

Working well as of now just need to make sure to heat up hot end before printing and tighten up the nozzle. You truly get a lot for the $$$$ and the quality is impressive at this price point.

Simple drop in replacement/swap, just relevel the bed and you're good to go!

Easy install and Worked like a charm on my printer after adjusting the z offset and re leveling the bed.

Bought this instead of replacing hotend. Works great. Just wish the printer was better.

My printhead that came with elegoo didn't work properly out of the box and when I tried to repair it I broke a crucial part, this replacement worked better than the original ever did.

I spent the beginning of my 3d printing career buying $175 Makebot extruders on a regular basis, so this feels like a great deal. I've done tons of printing and am on my two neptune printers, and am on 3rd replacement across two printers. I 3d print prototypes professionally, They're cheap enough that for me it makes sense to just keep a spare rather than spend engineering time trying to fix a messed up one. Great product. The low cost means I can keep a spare on hand, and the quick changeout time means even a total extruder failure means almost no down time.

The media could not be loaded. installed without issue but 1.75 mm PLA not loading after following Elegoo's official video

After a year, my extruder was having all sort of issues. I thought it was a heat creep issue, but it wasn't. I basically decided to stop messing around and just replaced the entire extruder. The new extruder prints great and it feels like a new printer again. Installation was simple, it's pretty much plug and play. Just re-adjust your z-index. Oh, that orange stuff is probably residue from the factory, so you'll need to obviously do a test load of your filament to get rid of it. It took several inches of filament to get rid of the color. So no, it wasn't a "used" extruder like that other reviewer assumed.
