'Experimental' at the Associate Professorship of Architectural Design and Building Envelope entail working on architectural designs in the context of Additive Manufacturing. In a special design class for master students, 'functional-geometries' for the building envelopes are developed and are produced up to the scale 1:1. The goal is to verify in 3d-printed architecture the boundaries of construction and the new design opportunities by reducing technical devices in the same time.
