Professor David Gethin’s research contribution in the scientific areas that support net shape manufacturing and printing and coating technology. During the last ten years, the Welsh Centre for Printing and Coating has undertaken fundamental scientific work on high speed, high volume graphics printing processes. This has revealed the fundamental understanding that is required to develop these processes scientifically (historically these developments were based on craft knowledge). Drawn on knowledge of thin film hydrodynamics to develop simulation methods and experiments to establish the fundamental process understanding. This work is now being taken forward with current application in the field of polymer electronics and with a future emphasis on biopolymers and biosensing devices.
