What is a Heat Break Used For?
The heat break sleeve is a crucial part of the extruder. It resembles a small hollow tube with a variable outer diameter. The MK8 heat break is made fr om stainless alloy steel, but there are also MK8 heat break models that incorporate bimetal materials.
The primary function of the heat break sleeve is to divide the extruder into two sections: the hot end, wh ere the filament is heated by the heating block and extruded onto the printing surface through the nozzle, and the cold end, where the heat break is located, and a radiator dissipates heat fr om the filament. This design ensures that the filament only melts in the heating block, maintaining the precision and quality of the 3D printer’s performance.
Please note that all MK8 heat break sleeves are exclusively compatible with MK8 and MK9 extruders or their equivalents.
MK8 Heat Break Sleeve Design Features
The MK8 heat break sleeve has an external M6 thread on one end for installation in the heating block. To prevent the filament from getting stuck inside the heat break and to reduce friction, some MK8 heat break models feature a PTFE (Teflon) tube. The tube is placed in a way that allows it to be easily removed and replaced without fully disassembling the extruder.
Another notable feature of the MK8 heat break sleeve is the absence of threads at the point wh ere it connects to the radiator. The radiator is secured using special "grub screws."
Important! Replacing the heat break sleeve must be done while the heating block is hot. Exercise extreme caution during the process!
