  3. Development of ceramic shells for rapid prototyping methods

    The development of methods for rapid prototyping of castings has recently received great attention. Possibilities of using 3D printing methods have started new so-called “hybrid technologies”, which combine the advantages of rapid production of patterns and related standard methods of casting production. It is expected to deliver a casting prototype at the highest quality and in the shortest possible time while maintaining the complexity of the required part. The technology of precise casting into ceramic shells is a very suitable technology following the above-mentioned methods of additive production of models, however, the present ceramic suspensions are primarily intended for the conditions of mass production and are not selected and optimized for wrapping specific printed materials and minimum drying time. The current water-based systems can be innovated by using specific additives based on polymers or nylon fibres, which can significantly improve the mechanical and technological properties of the manufactured shells. More detailed information on the composition of individual suspensions, their suitability for rapid prototyping and optimal drying processes are not more or less available and mastering the topic requires deeper knowledge.
