Leak-proof nozzle:
Tired of annoying nozzle leaks that ruin your prints and waste filament? The FlowTech Hotend combines the nozzle and heat barrier into one permanently sealed unit, ensuring a leak-proof hotend.
Cold nozzle replacement:
Replacing nozzles used to be a time-consuming and potentially dangerous task. With a FlowTech Hotend, nozzle replacement is simple, requires no heating or post-tensioning, and can be done with one hand.
High-flow properties:
The ceramic cylindrical heater and a 28.6 mm melting zone provide excellent volumetric flow rate.
Full metal construction:
Built to last! The FlowTech hotend features an all-metal construction that can handle most modern 3D printer filaments. The entire hotend is machined and assembled in-house, with quality control at multiple stages of the manufacturing process. Finally, each hotend undergoes a full thermal cycle test before being packaged.
300°C Max. temperature:
This hotend is approved for temperatures up to 300°C with a properly matched NTC thermistor for each specific printer. This version is perfectly matched to the Elegoo Neptune 4 and 4 Pro, so no firmware changes are needed.
