Abstract A mold material system has been developed that can be SLS processed and used to cast titanium alloys. Stabilized zirconia, chosen for its low reactivity with molten titanium, has been sintered into mold shapes. The molds have been infiltrated with a colloidal solution of unstabilized zirconia and fired to create a partially stabilized structure. SEM analysis shows that the unstabilized zirconia forms bridges between the larger stabilized zirconia particles that provide strength to the mold. (Auth abstract) [References: 8]
