This research project attempts to examine to what extent the technological capabilities of open source 3D printing could serve as a means of learning and communication. The learning theory of constructionism is used as a theoretical framework in creating an experimental educational scenario focused on 3D design and printing. In this paper, we document our experience and discuss our findings from a three-month project run in two high schools in Ioannina, Greece. 33 students were tasked to collaboratively design and produce, with the aid of an open source 3D printer and a 3D design platform, creative artifacts. Most of these artifacts carry messages in the Braille language. Our next goal, which defined this project's context, is to send the products to blind children inaugurating a novel way of communication and collaboration amongst blind and non-blind students. Our experience, so far, is positive arguing that 3D printing and design can electrify various literacies and creative capacities of children in accordance with the spirit of the interconnected, information-based world.
