Verfahren zur Herstellung keramischer und/oder metallischer Bauteile

The invention relates to a method for producing ceramic and/or metal components, in which a supporting structure which encloses at least one free space is formed using a polymer, and in which at least one free space is filled at least in a predefinable region with a plastically deformable or liquid mixture of at least one metal powder or ceramic powder and at least one organic binder. The mixture bears at least partially against the wall of the supporting structure. Then, during a first heat treatment, the mixture is transformed into a state having sufficient rigidity to maintain the geometric shape thereof and a temperature is maintained at which the polymer forming the supporting structure remains shape-stable. Then, during a second heat treatment, the temperature is increased and thereby the polymer forming the supporting structure is completely disintegrated and the metal powder and/or ceramic powder is sintered.
