Patent ID: 8256091

Claim:
A process of making uniform sized spherical beads comprising: a) providing a cell sheet having an array of cell sheet through holes; i) the cell sheet through holes each have equal cross sectional areas; ii) the cell sheet having a nominal thickness wherein the cell sheet nominal thickness is equal at each cell sheet through hole location; b) mixing at least two distinct materials into a liquid medium that is hardenable or solidifiable, the liquid medium comprising: at least one i) inorganic molecules, organic materials, metals, and at least one ii) a liquid carrier; c) filling the cell sheet through holes with the liquid medium to form liquid medium volumes wherein the volume of the liquid medium contained in each liquid medium volume is approximately equal to respective cell sheet cell volumes; d) ejecting the liquid medium volumes from the cell sheet by subjecting the liquid medium volume contained in each cell to an impinging fluid wherein impact of the impinging fluid dislodges the liquid medium, volumes from the cell sheet thereby forming independent liquid medium entities; e) shaping the ejected independent liquid medium entities into independent liquid medium spherical entities by at least surface tension forces acting on the liquid medium lump entities; and f) introducing the independent spherical liquid medium entities into a solidification environment to at least solidify the surface of the independent spherical liquid medium entities to form independent, uniform sized spherical beads.
