摘要： A process for the additive manufacture of a metallic and/or vitreous and/or ceramic component, a mixture of substrate particles and an at least two-phase binder is firstly provided. The mixture is preferably provided as composite particles, so that the substrate particles adhere to one another by the at least two-phase binder. The mixture is selectively melted layerwise by electromagnetic radiation so that a shaped part is additively produced. The shaped part is taken out from the mixture which has not been melted and the at least two-phase binder is subsequently removed, preferably successively. The process produces a microporous shaped part which after sintering leads to a component having a desired density and a desired mechanical and/or thermal stability.
