Product information

Upgrade your Ender 3 V3 SE printer with the FlowTech hotend kit and enjoy the convenience of cold nozzle changes, leak-proof nozzles, and a significant increase in flow rate.

This kit comes with a plug and play Heater Core and thermistor, fully compatible with Ender 3 V3 SE printer without any need for firmware adjustments!

Additionally, to accommodate the extended length of the FlowTech nozzles, we provide a CR touch spacer along with a modified part cooling fan duct.

  • 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 Creality Ender 3 V3 SE so no firmware changes are needed.
