A core-sheath filament having a) a core that is a thermally conductive pressure-sensitive adhesive particles and b) a non-tacky, thermoplastic sheath is provided. The thermally conductive pressure-sensitive adhesive in the core includes a (meth)acrylate-based polymeric material and thermally conductive particles. Additionally, methods of making the core-sheath filament and methods of using the core-sheath filament to print a thermally conductive pressure-sensitive adhesive are described.
