Tired of heat creep getting you down and ruining your prints? Eliminate it with the Copperhead Bimetallic Heat Break. Unlike most heat breaks which are monolithic (composed of only one material), the Bimetallic Heat Break is composed of multiple materials. Like a composite, these heat breaks use the differing material properties of the two metals (super conducting copper and poorly conducting hardened steel) to force the heat from your 3D printer to go where it should. The copper allows the heat to distribute evenly in the hot section, the hardened steel prevents the heat from moving up the filament path, and the copper in the cold section rapidly dissipates any heat to the heat sink. Bring some materials engineering technology to your 3D printer, eliminate heat creep, and be happy with your 3D printer again.
