CR10 Hotend Extruder Long Distance Titanium Alloy Heat Thermal Break Throat for Creality CR-10 3D Printer

Thermal heat breaker is made of titanium alloy to provide excellent thermal insulation

between the heater and the cooling block. Titanium is an extremely strong material and offers almost

3x the lower thermal conductivity of stainless steel, creating a more defined meltzone.

What is the difference for ''1.75-0.4mm'' and ''4.1mm bore (upgrade)''

The difference between these two models is the inner hole for the throat, see the drawings below .

How do you choose which size to buy?

If your printing temperature is within 0 °C- 220 °C, then choose ''4.1mm bore (upgrade)'' , in this way, there will be no blocking condition.

If your printing temperature is in the range of 260 °C-300 °C , then choose ''1.75-0.4mm''.
