To shorten the cycle time in conventional hot emboss-ing, an infrared laser (laser/IR)-assisted microemboss-ing process was investigated in this study. Since the laser/IR heats the substrate rapidly and locally, the heat-ing and cooling time can be substantially reduced. Two different modes of IR embossing were tested. In one case, the polymer substrate was the IR-transparent poly(methyl methacrylate) (PMMA) and a carbon black-filled epoxy mold was used. In the second case, the polymer substrate was an IR-absorbent PMMA, and an IR transparent epoxy mold was used. The experimental results showed that both a shorter cycle time and good replication accuracy could be achieved. A commercially available finite element (FEM) code, DEFORM™, was use...
