David is a Research Officer based in the Welsh Centre for Printing and Coating. Having completed a PhD researching ink transfer mechanisms in flexographic printing David's research interests have grown to include graphics, electronic and functional printed materials. Recent projects have included printed functional devises including electromagnetics, sensors and rheological characterisation of functional inks working in collaboration with academic and industrial partners. David currently works on the Centre for Innovative Manufacture in Large Area Electronics (CIMLAE) project formulating functional inks for the ARPLAE and Flexipower projects.
Advanced Rheology for Printing Large Area Electronics (ARPLAE) project will address fundamental rheological barriers to achieving high resolution features in high yield contact printing processes. Improved understanding of the rheological aspects of these processes is required to establish a rigorous basis for their better prediction and control. This project is part of the Advanced Manufacturing Process theme within the Centre's technical programme. Phase 1 of the project involves a 6-month scoping study, the subsequent phase being an 18-month technical programme. Its overall objectives are to:
The development of industrially deployable performance metrics will be based on robust, fundamental measurements and their analysis, and the project will also assess rheometric approaches to the characterization of rheologically complex functional ink systems, these approaches being based on adapted forms of instrumentation used in other related fields.
