Abstract (en)

[origin: WO2017089498A1] The invention relates to a method for producing a three-dimensional component from a composite material containing carbon and metal, comprising the following steps: a) providing a composition in powder form comprising one or more components, which are selected from the group consisting of amorphous carbon, graphite, and hybrid forms thereof, b) providing a liquid binder, c) depositing a flat layer consisting of the material provided in a) and locally depositing droplets of the material provided in b) on said layer and repeating step c) any number of times, wherein the local depositing of the droplets is adjusted in subsequent repetitions of this step according to the desired shape of the component to be produced, d) curing or drying the binder at least in part and obtaining a green body having the desired shape of the component, e) carbonizing the green body at a temperature of at least 500 °C, and f) infiltrating the carbonized green body with a metal at a temperature above the melting temperature of the metal.
