The
polystyrene expands and takes the shape of the die cavity. Additional heat is
applied to fuse and bond the beads together. The die is then cooled and opened,
and the polystyrene pattern is removed. Complex patterns also may be made by
bonding various individual pattern sections using hot-melt adhesive (Section
32.4.1).
