Abstract: A thermal management device includes a single contiguous component. The single contiguous component includes a first portion made of a first thermally conductive plastic, and a second portion extending away from the first portion. The second portion is made of a second thermally conductive plastic. The second thermally conductive plastic is different than the first thermally conductive plastic. The second portion has a greater hardness than the first portion.

Abstract: In order to provide a thermally conductive polymer based filament that may be printed using additive manufacturing techniques, a composition includes a thermoplastic polymer and/or elastomer that is soft and pliable, a polar polymeric thermoplastic, and a thermally conductive filler. The composition includes from 15 to 80 weight percentage of a thermoplastic polymer and/or a thermoplastic elastomer, from 20 to 85 weight percentage of a thermally conductive filler, and from 0 to 25 weight percentage of a thermoplastic polymer having polarity on a main chain of a molecule that results in a dipole moment. The thermoplastic polymer and/or the thermoplastic elastomer has a combined Notched Izod impact strength greater than or equal to 300 J/m and a flexural modulus less than 3 GPa. The filler has an intrinsic thermal conductivity greater than or equal to 1 W/m-K. The composition is characterized by a thermal conductivity of at least 0.75 W/m-K and an Izod notched impact strength of at least 100 J/m.
