We report on the hot roller embossing of polymer sheets for the creation of microfluidic structures. Measurements conducted on 100 μm features showed that the lateral dimensions could be replicated to within 2 over 85 feature depths up to 30 μm had been achieved. At lower temperatures, asymmetric pile up of polymer material outside embossed regions was observed with higher pile up occurring on the trailing side of the embossed regions.
