Abstract

For almost two decades, layer manufacturing techniques have assisted the product development at various stages from the operational point of view. Laser sintering is a powder-based layer manufacturing technology. Since the beginning of the 1990s, laser sintering of ceramic materials has been investigated academically. Since laser sintered bodies are porous correlating with a comparatively low strength, industrial use is still limited. This paper provides a knowledge base for laser sintering of ceramic suspensions. Therefore a model based on system analysis is generated, which is sub-divided into a drying and a process model. Furthermore experimental investigations with different high-performance oxide ceramic slurries (e.g., zirconia) are conducted in order to approve the estimations of the model.
