The Practise Fabrication // Lightweight Structures 1:1 Seminar, led by Silvia Brandi and Rodrigo Rubio, with the collaboration of Pepe Ballesteros (Prototipolab) and Maria Kupstova, is focused on the digital fabrication of lightweight 1:1 scale spatial installations, based on the expertise of Experimental Structures, and the further development of some concepts proposed in Public Space Capsules Seminar from Term 2. The aim of the Seminar is to realize lightweight spatial installations (embedding textile materials) that are demountable, digitally fabricated, and eventually performative. The students have formed 4 different groups, each one working on a different structural prototype implementation. In these first 3 days of the seminar each group worked their concept design, testing the structural capacities through the production of small scale prototypes. The course counts on the collaboration of the company SERGE FERRARI, an international producer of flexible composite materials and membranes of high performances for architecture, who will provide the material for the construction.
