TPU Based Ice9 Filament - Thermally Conductive and ESD Safe
Ice9 TPU is an advanced graphite based thermally conductive composite. It is semi-flexible and has a thermal conductivity of 6 W/m-K in the print direction. It works best with direct drive systems and any FDM printers that print flexible filaments. The filament exhibits electrostatic dissipative properties making it ESD safe. The fillers improve temperature stability and provide the composite material with a usable temperature up to 110°C. The material is ideal for heat sinks, heat exchangers, battery packs, liquid cooling, and the most demanding thermal applications.
