Ceramic laser rapid prototyping technology is a new process of layer manufacturing using ceramic slurry. A 3D workpiece can be fabricated by repeatedly executing the cycle of single layer making.
The aim of this study is to develop a Ceramic Laser Sintering rapid prototyping apparatus. The dimensional accuracy and surface roughness of the ceramic model fabricated by this new apparatus can be improved. Furthermore, to develop a drying technique, which can lead to a result of layer instant drying without cracks, is another task of effectively reducing the time-taken of fabricating model. Finally, a strategy of fabricating ceramic sintering models will be built by studying parameters related to laser scanning, and strength of the ceramic sintering models then can be improved by followed infiltration.
Firstly, studying started from the developing of a ceramic laser sintering apparatus; the accuracy of
