The Copperhead is a low-cost, open-source hotend option that can handle the heat heat creep, that is. Replace your factory model hotend with the Copperhead, to upgrade your 3D printers performance and reduce jamming, giving you a smooth print every time.

Unlike most materials, plastics dont have a clean transition from solid to liquid during melting. As filament moves through the hotend, it heats up and reaches the materials glass transition temperature (Tg), entering a semi-solid, semi-liquid, gooey state. While in this state, the plastic responds to applied forces like a wet noodle, causing undesirable print effects like reduction in resolution, blobbing and jamming. An efficient heat break narrows the physical distance during which the plastic is at its Tg, and thus improves 3D printer performance. The Bimetallic Heat Break from Slice Engineering is the only heat break designed through the use of thermal imaging to optimize heat transfer.

We highly recommend the use of Boron Nitride paste with the Copperhead to provide good thermal conductivity between the hot block and heater/thermistor.
