FlowTech™ Hotend for Creality Ender 3 V3 KE

The FlowTech™ Hotend is a new generation hotend line from Micro Swiss. Its unique design eliminates common hotend issues such as leaking nozzle seal and complex nozzle swaps.

Keeping with our philosophy, the FlowTech hotend is designed to be an easy drop-in upgrade for each 3D printer model. This edition is designed for Ender 3 V3 KE. Stock z-height, build volume and firmware remains unchanged.

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 Ender 3 V3 KE so no firmware changes are needed.

Great product, amazing instructions

This hot end was better than the factory one from Creality and the instructions were the best instructions I’ve ever seen for anything in my entire life. Colour photos, clear explanations in perfect English. Hats off to whoever made them!!! 😘

Not sure if user error

I purchased the hot end for my v3 ke thinking the design was better and more solid. Less chance of the hot end turning into a ball of molten plastic like the last one. I got 2 prints in and it did the same thing again but I managed to catch it before it ruined the printer. When trying to remove the nozzle with a ratchet the head snapped off completely and the screw heads were completely filled with plastic so removal was almost impossible. Another one bites the dust I suppose... Took me almost 5 hours just to save the heat sink...

Easy install, works great

This was a very easy install. Watched a good youtube video before install. I like the fact I can do a cold nozzle replacement. Broke my OEM nozzle trying to take it out as it apparently wasn’t hot enough and snapped off inside the hotend. The Micro Swiss replacement has been flawless in the first 50+ hours of use. Pleased with my purchase. Shipping was prompt.

Solid Hotend Replacement

I swapped out my stock hotend and heatsink for the this replacement. Never looked back. I also paired this hotend with the CM2 nozzle. Have printed PLA, PETG, and TPU without any issues. Highly Recommend.
