The concept of obtaining Rapid Prototypes build up on Ceramic materials is increasingly being an object of study due to the multiple applications of different Ceramic compounds, for instance, in the biomedical or in the aerospace industries. However, technical ceramics are much difficult to machine than other materials due to special characteristics such as fragility, dustiness and abrasive behaviour. As a difference to studies that approach the realisation of Ceramic prototypes by the application of layered manufacturing technologies, the purpose of this work is to analyse the specific features of technical ceramic materials and to develop a methodology for the materialisation of ceramic rapid prototypes based on subtractive methods. In the present study, the ceramic material is compacted on a cylindrical preform and then machined into a geometry that will then be sintered, deforming to the final shape required. The study presents the most relevant points of the methodology and the potential outcomes of its application.
