Hemera stainless steel HeatBreak A replacement 1.75mm stainless steel Hemera HeatBreak. Although this HeatBreak uses an M4 thread on the cold side, the hot side remains an M6 thread to maintain compatibility with the V6, Volcano and Super Volcano heater blocks. Hemera titanium HeatBreak Titanium Hemera HeatBreaks are the perfect upgrade for printing at higher temperatures, helping to maintain a sharply defined melt zone at higher temperatures. Genuine E3D HeatBreaks feature a refined internal surface finish to reduce extrusion force and improve retraction reliability. Made from grade 5 titanium, these HeatBreaks are exceptionally strong and have lower thermal conductivity than stainless steel HeatBreaks, allowing you to keep the cold side of your HotEnd even colder. The increased strength of these breaks means that they are also much less likely to crack or snap, either while hot-tightening or on the occasional collision with printed parts or printer bed.
