Hot end

The hot end is the part of an FFF (Fused Filament Fabrication) printer that heats up and actually melts the plastic. A hotend includes the heat block, heat break and cooling fins. The cooling fins and active cooling fans on some hot ends prevent heat from affecting the rest of the print tool. Often written hot end, hotend or even hot-end.
