Complete Digital Fabrication of Polymeric Microsieves
Abstract:We report on the substitution of a fabrication step for the manufacture of polymeric microsieves, carried out manually so far, by an inkjet printing technology. As published previously  the microsieves are manufactured by using a solution of Poly(methyl methacrylate) (PMMA) in chloroform. However, this solution is not printable with an inkjet printer due to its high vapor pressure. Hence, the PMMA solution was replaced by a commercially available UV curable ink to enable inkjet printing. This variation of the ink leads to a UV exposure driven fabrication method enabling the prospective production of microsieves with an automated high throughput manufacturing. Additionally, the digital fabrication character of inkjet printing allows the manufacture of customized microsieves for given filtration application requirements like size selectivity and mechanical stability.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
