Abstract: The present invention relates to a three-dimensional component consisting of a composite material containing carbon particles in a plastic matrix, to a method for producing the component and to the use of the component. The method for producing a three-dimensional component consisting of a composite material containing carbon and a plastic comprises the following steps: a) provision of a pulverulent composition comprising one or more components selected from the group consisting of amorphous carbon, graphite and mixed forms thereof, b) provision of a liquid binder, c) planar deposition of a layer consisting of the material provided in step a) and local deposition of droplets of material provided in step b) onto this layer and any number of repetitions of step c), the local deposition of the droplets in the successive repetitions of this step being adapted according to the desired shape of the component to be produced, d) at least partial curing or drying of the binder to obtain a green body that has the desired shape of the component, e) impregnation of the green body with a liquid synthetic resin and f) curing of the synthetic resin to produce a synthetic resin matrix. The invention also relates to a three-dimensional component consisting of a composite material comprising carbon and a plastic, characterised in that the component comprises between 25 and 50 wt. % plastic matrix and between 50 and 75 wt. % carbon in at least a partial particulate form and said carbon particles have on average a form factor (width/length) of at least 0.5 in the particle-size range of the d50 value.
