Abstract
A method for forming a carbon-metal composite material for a heat sink, comprising the following steps: applying at least one layer comprising carbon particles and at least one layer comprising metal particles on top of one another; and fusing of the layers by irradiating the layers with laser radiation to form the carbon-metal composite material. The invention also relates to a heat sink having a shaped body that comprises a plurality of layers, each layer containing carbon particles in a metal matrix.
