Upgrade your Ender 3 V3 SE printer with the FlowTech Hotend Kit and benefit from the convenience of cold nozzle changes, leakproof nozzles and a significant increase in flow rate. This kit includes a plug-and-play heating core and thermistor and is fully compatible with the Ender 3 V3 SE printer – without any firmware adjustments! To take into account the longer length of the FlowTech nozzles, we also supply a CR-Touch spacer and a modified fan duct. Leakproof nozzle: Are you tired of leaking nozzles that ruin your printing and waste filament? The FlowTech Hotend combines the nozzle and the thermoblock in a permanently sealed assembly to ensure a leakproof hotend. Cold nozzle changes: Changing nozzles used to be time-consuming and potentially dangerous. With a FlowTech Hotend, nozzle changes are effortless, without hot-tightening and can be done with just one hand. High flow rate: The cylindrical ceramic heater and the 28.6-mm melting zone ensure an excellent volume flow.
