Further scaling of functional screen printing is challenging because printing fine structures at highest production speeds requires careful accordance of screen design and printing paste properties.  The PV industry is a great example because Ag-electrodes on Silicon solar cells are printed down to widths of only 20μm at high printing speeds.  We present our latest research on modeling and simulation of screen technology.  Our algorithm is able to analyze and optimize arbitrary screen layouts in terms of its functionality and utility during the screen printing process.  We further present our technology roadmap towards a fully autonomous digital twin for fine-line screen printing.
