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.
