Package includes choice of 1 or 2 Titanium Heat Breaks
$9.99 – $15.99
One of the most annoying problems with hotends is thermal creep, that leads to clogs and under extrusion. Heat creep is when the heat radiating from the heater block starts to go up the heatbreak (Throat) and high into the heatsink at a rate where the heatsink can’t radiate it out into the air fast enough. The extra heat in the heatsink leads to melted plastic that can lead to under extrusion at best and an annoying clog at worst. Titanium has a lower thermal conductivity rate than does aluminum or steel. The lower thermal conductivity prevents excess amounts of heat to transfer up the heatbreak into the heatsink while also lowering energy requirements to the heater block at the proper temps. (But this is a minimal benefit at best) the main benefit being reducing the amount of heat needed to be dissipated by the heatsink.
