micromoulding solvent-assisted micromoulding CHMO:0001434 SAMIM A process for shaping pliable polymer materials using a microsized rigid frame or model called a 'mould'. The mould is wetted with a thin layer of solvent. When the polymer is brought into contact with the mould, the top layer of polymer dissolves and expands, filling the mould. The solvent is then allowed to evaporate. solvent-assisted micromolding
