ProtoSpray is a new fabrication method that combines 3D printing and spray coating, to create touch-sensitive displays of arbitrary shape. Our approach makes novel use of 3D printed conductive channels to create base electrodes and shape displays. A channelled 3D printed object is then combined with spraying active, electroluminescent, materials to produce illumination. This demonstration involves multiple different devices, created through the ProtoSpray process, showing its free-form applicability to irregular shapes such as a mobius strip and spherical surfaces. Our work provides a platform to empower makers with displays as a fabrication material.
