20mm Heater Cartridges

Description

These are the cartridges that heat the nozzle. 40w are more than sufficient for standard printing. If you are using high temperature material, large aperture nozzles or high speed, 50w will provide a more rapid flow of molten plastic. Please note that these are the size cartridges to fit the volcano heat blocks. Although they will work in a standard heat block approximately 5mm will protrude, for a standard heat block you should use 15mm heater cartridges.
