A well-dispersed colloidal suspension of 20 vol.% ZrO2 particles (d = 0.5 m, = 5.44 g/cm3) in a liquid medium ( = 1.13 g/cm3) is jet printed on a flat substrate in tracks 650 m wide x 120 m (wet). Assume the tracks in cross-section remain rectangular with square corners and the drying shrinkage occurs in the thickness direction only. Calculate the thickness of a dry track if the ZrO2 particles in the dry track have a packing factor (relative density) of 0.55
