In June 2015, MX3D announced that they were planning on building a fully functional 3D printed stainless steel bridge. The bridge will be placed on the Oudezijds Achterbrugwal located in the red light district. Because the bridge is pushing construction and modelling techniques, the bridge will also be fitted with a sensor network. The sensors will monitor the structural health and use of the bridge to ensure the bridge’s lasting integrity. MX3D wants to know how the data that the bridge collects can become meaningful to a public audience. The design challenge of this graduati-on project is to develop a data driven lighting design for MX3D's sensor equipped 3D printed bridge, to engage a public audience with the bridge and to convey the smartness of the bridge. Through the exploration of the bridge, the location, the data and lighting technologies, multiple concepts were found using side emitting optical fibres. The final concept led from the results of a user test: A lighting design from side emitting optical fibres, that conveys the amount of people through the amount of lines that are turned on. The lighting design glows in a constant motion to convey that the bridge is a living and breathing entity, that is aware of its surroundings. The colour of the lighting design is light blue, the colour of smart technology.
