Free shipping in Canada for orders over $140 before tax. (via Canada Post)

Titanium heatbreak for the MK8 hotend.  Convert your MK8 hotend to an all-metal heat break with Spool3D's titanium option. 

Our heat break is manufactured to tight tolerances using a special titanium alloy and a polished filament path.  We use titanium alloy Ti-6Al-5Zr-0.5Mo which is different from the industry's most common, Grade 5. Ti-6-5-0.5 has the lowest thermal conductivity among wrought titaniums.  This translates to 38% less heat transfer than Grade 5 titanium and  72% less heat transfer than typical stainless steel heat breaks and thermal tubes.

A lower thermal conductivity means a shorter transition zone where the filament changes from solid to liquid. Higher retraction values are no longer necessary.

Thermal paste must be applied to the threads of the heat sink side:
