Reactive inkjet printing of polyurethane

Piccin on rapid prototyping, and microchips from that material e, photolithography served as ron feature resolution typically techniques, inkjet printing was technique is also called reactive inkjet printing, and is a precise method for building up small PAPER www.rsc.org/materials | Journal of Materials ChemistryNetherlandsstructures using certain reactive materials, like PU. We here demonstrate that definedmicron-scale PU-based structures can be fabricated via reactive inkjet printing starting from the corre-sponding monomers in a reactive, in situ manner on glass substrates. This approach yields unique, cross-linked thermoset PUmaterialswith spatial resolution in the rangeof tensofmicrons. Another aim of this research is to explore the use of inkjet printing as a technique for undertaking moisture-sensitive aLaboratory of Organic and Macromolecular Chemistry
