The effect of particle characteristics and polymer rheology on the fabrication of sintered ceramic microarrays using powder injection modling is examined. The impact of material composition on microfeature resolution and defect avoidance during processing was investigated using experiments and finite element modeling. The evolution of defects in alumina microfluidic structures at the microscale (particle level) and macroscale (part level) using several surface analytical imaging techniques. These findings are of importance for fabricating microfluidic ceramic strucutres for operating at high temperatures (uptyo 1600oC) and aggressive chemical environments are illustrated.
