VERFAHREN ZUM HERSTELLEN EINES BAUTEILS AUS METALL ODER WERKSTOFFEN DER TECHNISCHEN KERAMIK
The invention relates to a method for producing a component from technical ceramics materials or sintering materials, comprising the following steps: First, a mixture of a binder and a ceramic or sintering granulate is produced (100). This mixture must be suitable for the additive manufacturing of a green body from the mixture. Once the mixture is available, a green body is produced by means of additive manufacturing (110). Said body is then isostatically compressed in the green state or in a fully or partially debound state or in a lightly sintered condition (150). The compressed component is then sintered (180). The increase in density before the sintering process (180) itself and the homogenization of the density distribution additionally resulting from the isostatic compression (150) allow higher sintering densities and significantly improved characteristics in respect of strength and other parameters to be achieved in the subsequent sintering process.
