Abstract Scope Additive manufacturing directly enables the production of complex-shape components. The downsides of the additive manufacturing technology such as the binder jetting is the necessity of conducting the complex and time-consuming debinding and the difficulty to achieve the full density of the components at the end of the sintering cycle. In the present work a novel sintering method to produce fully dense ceramic complex-shape components is presented. The proposed selective sintering technique combined with the powder bed 3D-Printing technology allows the fabrication of fully dense complex shape parts. The process is composed of four steps: 1) Fabrication of powder mold; 2) Injection of powder or slurry in the mold; 3) Isostatic pressing of the sacrificial mold and powder assembly; 4) Sintering. The possibility to design an optimal sintering cycle through a model and the advantages of this process regarding sinterability, grain size retention, short process time, and improved microstructure are discussed.
