A polymer encapsulated silicon carbide system has been developed for
use with Selective Laser Sintering. Extensive studies with this material
have provided information pertaining to processing and material
parameters which most affect the strengths and densities of resulting
green parts. The important parameters considered were particle size
distribution of the powders, laser scanning conditions, and laser beam
diameter. Simple and complex shapes were easily produced with this
material using optimized parameters. Green objects were infused with
metal by Lanxide using their pressureless infiltration process to produce
both metal matrix and ceramic matrix composites.
