Neil Chilton  from Printed Electronics Limited U.K. gave the tutorial “Printed Electronics 101 – an overview of inkjet and additive manufacturing methods”. A six hour tutorial which clearly gave me a deeper insight in possibilities and challenges with inkjet printing and additive manufacturing methods for production of electronics. Neils tutorial goes through inkjet printing (material deposition) five basic elemnts: ink(s), inkjet head(s), substrate(s), functionalisation and the platform(machine). The inkjet system’s function is: to deliver the right amount of ink; meassured in carefully dispensed drops,; as accurately as possible; to a substrate that is in motion with resepect to the head; all in a one millimeter journey between the head and the substrate. Clearly this is a challenge!
