One of the goals of 3WELES project is to fabricate fully functional microcontroller circuit, printed and 3D printed, with additional discrete components. An electronic circuit from silver paste was screen-printed on an elastic substrate, and elements were attached with electrically conductive adhesive. This allowed to fabricate a fully functional clone of Arduino™ microcontroller but based on a fully printed circuit, instead of PCB. We are currently working on 3D printed PRINTduino™, fabricated with elaborated materials, and with FDM and DW techniques.
This project was a part of a bachelor thesis „Applications of electrically conductive adhesives for assembly of printed electronics on a low temperature and elastic substrates” by Paweł Sawczuk.
