Laser sintering of alumina slurries

Since the middle of the 80s, layer manufacturing technologies have assisted the product development at various stages from the operational point of view. By now laser sintering is known as a powder-based layer manufacturing technology. Laser sintering of ceramic material has been investigated academically for years. As 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 Alumina slurries. Therefore a model of the slurry laser sintering process based on system analysis is generated, which is sub-divided into a drying and a process model. Furthermore experimental investigations with high-performance alumina slurries are conducted in order to approve the estimations of the model.
