The elective ADDFAB is open for students in the Master at the TU Berlin. The course focuses on the use of large scale additive manufacturing for the design and production of architectural building elements. Architecture is often referred to as protection against rain, heat and wind. As with additive manufacturing it is not necessary to produce a large number of equal components, building elements as “series of single parts” could be thought of, which are optimized for the climatic context in which they are used. In this research-by design project architects in collaboration with external partners from industry and research institutes explore the functional and aesthetic potentials of additive manufacturing processes for the design of 1:1 building elements which integrate climatic functions. Inspired by architectural precedents and natural systems, ventilation, channeling flows, evaporative cooling and/or insulation functions are integrated in building elements with a unique functionality and aesthetic unprecedented in traditional manufacturing processes.
