Microchannel designs were prototyped to demonstrate three typical applications in microfluidics. The turn-around can be accomplished in 3 h with no cleanroom facility. The developed SR-3000 with engraved open patterns can be sealed, after plasma-oxidation, to poly(dimethylsiloxane) (PDMS) with a good strength of bonding as high as the 340–410 KPa (50–60 psi) range, strong enough to hold pressure for typical microfluidic applications. Tracing paper printing is suitable for engineering and architectural drawings, it is chosen by artists as a different material and can be used on various. Translucency and dense blacks make it ideal for diazo and xerographic reprints. It is an economical alternative to vellum. The patterned photoresist is developed by spraying with pressurized warm water, which makes this method unique and environmentally friendly. Catch Your Moments - Offering Glossy Transparent Paper For Inkjet Printer Size-A4, For Mobile Cover Print, GSM: 80.0 g/m2 at Rs 30/piece in Gandhidham. HP Translucent Bond can be used for reproducible drawings and check prints. It follows by transferring the patterns to the dry-film photoresist by low-dose UV exposure. In this method, the photomask is prepared by printing microchannel patterns to either a sheet of Vellum paper or a transparency by an office laser printer. This method is based on the use of a negative, water-developable dry-film photoresist as the structural material. A new, rapid, environmentally friendly prototyping method is presented.
