FlowTech™ Hotend for 
ELEGOO Neptune 4 Plus / 4 Max

Installing this hotend on Elegoo Neptune 4 Plus and Neptune 4 Max printers is a very quick and easy process. The kit comes with a plug and play Heater Core, thermistor and a heatsink fully compatible with Neptune 4 Plus and 4 Max. 
Stock z-height, build volume and firmware remains unchanged.

Upgrading your Elegoo Neptune 4 Plus and 4 Max to a FlowTech ecosystem allows you to use a full range of FlowTech, leak-proof nozzles including Diamondback nozzles that have a solid diamond tip - NOT a diamond coating.

Made in USA by Microswiss

  • Leak-Proof Nozzle:
    Tired of messy nozzle leaks that ruin your prints and waste filament? FlowTech Hotend combines nozzle and thermal break into one permanently sealed assembly that ensures a leak-proof hotend.

  • Cold Nozzle Change:
    Swapping out nozzles used to be a time-consuming and potentially hazardous task. With a FlowTech Hotend, nozzle changes are effortless, and there's no need for hot tightening, and you can do it with just one hand.

  • High-Flow Characteristics:
    Ceramic cylindrical heater and 28.6mm melt zone provides excellent volumetric flow rate.

  • All-Metal Design:
    Built to last! FlowTech hotend features an all-metal design that can handle most modern 3D printing filaments. The entire hotend is machined and assembled in-house, with quality control performed at multiple stages during the manufacturing process. At the end, each hotend undergoes a full thermal cycling test before it is packaged.

  • 300°C Max Temperature:
    This hotend is rated at 300°C temperature with a properly tuned NTC thermistor for each specific printer. This particular edition is perfectly tuned for Elegoo Neptune 4 Plus and 4 Max so no firmware changes are needed.

Awesome hot end

Needed this as my hot end malfunctioned and stopped working with it going to take the manufacturer over 2 weeks to ship me a replacement. And I am glad I found this one as I have not had such beautiful consistent prints. Great aftermarket hot end.


Works as expected. Not sure if it out performs stock hotend but cold nozzle changes are pretty nice!


FlowTech™ Hotend for ELEGOO Neptune 4 Plus / 4 Max

An amazingly simple, fantastic performing, drop in upgrade

I've heard great things about Microswiss for years now in the 3d printing space, so when I saw they'd come out with a FlowTech hotend for the N4Max I had to give it a shot, and let me tell you, it is phenomenal, and in my case, cost less than buying a replacement O.E. Hotend from Elegoo. Being able to do cold nozzle swaps, and speed up my prints even further has helped me churn out props faster, and with significantly less failures!

Works perfectly on my Neptune 4 MAX

Fits great and works great, more consistent layer lines and a better volumetric flow. Excellent upgrade.
