Research in SIMTech

Large Area1 1


Conventional electronic circuit fabrication relies on lithography and subtractive processes. The growing need to achieve cost-effective, energy-efficient and environmentally-friendly manufacturing is driving a paradigm shift towards large area manufacturing processes, widely known as printed electronics. The LAP leverages SIMTech’s interdisciplinary manufacturing technologies and competencies to research, innovate, and commercialise large area manufacturing processes for emerging and use-inspired applications. Key research on disruptive manufacturing processes extends to large area screen printing, roller embossing, and ink-jetting.
