DESCRIPTION +

Open-Source Ecosystem
Copperhead is open source and published under a CC-BY-SA 4.0 license. Its modular heat break system integrates easily into virtually any heat sink design. Copperhead Heat Breaks are made with the same bimetallic technology found in the Mosquito®’s signature Bimetallic Heat Break™ but with a thicker wall for superior impact and abrasion resistance.

Bimetallic Heat Break™
Copperhead Bimetallic Heat Breaks are 60% more efficient at heat creep reduction than monolithic designs. Using the same high-strength copper alloy designed for optimal thermal conductivity found in Mosquito Heat Breaks, Copperhead Heat Breaks boast a higher temperature rating and flow rate potential over PTFE-lined heat breaks.

Adjustable Z-Height for Dual Extrusion Setups
Machined out of aircraft-grade aluminum, the Copperhead Heat Sink’s shaft collar enables easy z-height adjustment of the heat break and hot block—making it ideal for dual extrusion setups. Whether creating intricate designs or experimenting with multi-material prints, the Copperhead Hotend effortlessly adapts to your specific requirements, opening up a world of possibilities.

Super-Conductive Hot Block
Copperhead is named for its hardened, nickel-plated, copper alloy hot block. Rated to 450°C, Copperhead enables printing of nearly every commercially available filament, from basic PLAs to medical-grade PAEKs. The hot block design isolates the sensor from the heater with a physical air gap, improving the temperature feedback loop, and features convenient wrench flats to simplify nozzle changes.
