Ice9 Rigid is a nylon based thermally conductive pellet with temperature stability above 150°C. The pellets are electrically non-insulating and has a thermal conductivity of 4 W/m-K in the print direction. These pellets extruded into filament is ideal for mold tooling and any applications requiring high thermal conductivity, stiffness and temperature stability. Ice9 Rigid works well with most standard FDM printers (with nozzles that can achieve at least 260°C print temperature
