Abstract
The present invention is a process for modifying the properties of a porous freeform fabricated part by increasing its density and reducing its porosity. The porosity and density of a freeform fabricated part are altered by packing the pores in a freeform part with an infiltrant, such as a preceramic polymer. The process includes drawing a vacuum on or pressurizing the freeform part while it is in an infiltrant bath, thereby forcing the infiltrant into the pores of the freeform part. After removing the densified freeform part from the infiltrant bath, the freeform part is subjected to a treating process, such that the infiltrant within the pores transforms to a ceramic or ceramic-containing phase to thereby increasing the density of the freeform part.
