Plug-and-Play Design
The Prusa i3 Copperhead Kit is a drop-in, plug-and-play replacement for the stock Prusa i3 Hotend. Utilizing the stock heat sink, heater, and sensor makes installation a breeze, allowing you to reap the benefits of the Copperhead hotend with minimal printer downtime.

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.

Super-Conductive Hot Block
The Copperhead Hot Block 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.
