Abstract

original image

Laminated object manufacturing, a rapid prototyping method, is applied to paper sheets containing SiC filler particles. Upon pyrolysis and melt filtration of Si, the sheets can be transformed into dense ceramic objects with complex shapes such as the 18-layered gearwheel shown in the figure.
