Conductive Filament

A specialized 3D printing material that conducts electricity, enabling printed objects to interact with capacitive touchscreens. In accessibility applications, conductive filament can be embedded in otherwise non-conductive 3D printed objects — such as tactile maps or overlays — to create specific regions that register as touch inputs when placed on a tablet or smartphone screen. This allows physical tactile artifacts to become interactive: when a user touches a conductive region on a 3D printed map, the touchscreen beneath detects the contact and can trigger audio feedback such as speaking a street name or location description.
