Indirect fused·· deposition process is utilized.·.. to ·fabricate controlled porosity ceramic
structures using alumina, mullite, zirconia, LSCF-perovskite, tricalcium phosphate and
hydroxyapatite, where pore size, pore shape and pore connectivity are varied from one end to
the other end of the parts. Some of these porous ceramics are then infiltrated with metals via
pressureless reactive metal infiltration to form novel metal-ceramic composites. Thispaper will
describe processing, structures of various porous and metal-infiltrated composites and their
physical and mechanical properties.Mechanical Engineerin
