摘要： A method for producing the component, and to the use of the component. The method for producing a three-dimensional, ceramic component containing silicon carbide, by a) providing a powdery composition having a grain size (d50) between 3 microns and 500 microns and comprising at least 50 wt % of coke, b) providing a liquid binder, c) depositing a layer of the material provided in a) in a planar manner and locally depositing drops of the material provided in b) onto said layer and repeating step c), the local depositing of the drops in the subsequent repetitions of the step is adapted in accordance with the desired shape of the component to be produced, d) at least partially curing or drying the binder and obtaining a green body having the desired shape of the component, e) carbonising the green body, and f) siliconising the carbonised green body by infiltration with liquid silicon.
