This essay investigates a new construction paradigm for the subdivision and articulation of interior architectural spaces, introducing an innovative patented system based on modular blocks with variable geometry. These elements, equipped with internal mechanical connections that can be activated and deactivated, ensure the structural and functional cohesion of partitions without the use of adhesives or mortar, allowing for high flexibility, reconfigurability, and adaptability to changing spatial needs. The research explores the theoretical and applicative foundations of this approach, analysing both its constructive logic and production methods. A key aspect is the use of indirect printing for manufacturing recyclable formworks in elastic polymers. This technique facilitates the creation of complex, high-precision geometries, optimizing material usage and enhancing sustainability. Compared to traditional and direct printing methods, it allows for cost reduction, greater production efficiency, and the realization of lightweight, small-scale modular elements (less than one cubic meter in volume and 15 kg in weight) in limited series. By integrating advanced technological solutions with a redefined spatial logic, this construction system introduces a transformative perspective in architecture. The possibility of quickly assembling, dismantling, and repositioning partitions supports dynamic, non-invasive interventions with minimal environmental impact, promoting a highly adaptable and sustainable housing model. The essay thus highlights how innovation in design, materials, and production processes can redefine contemporary construction paradigms and respond effectively to evolving architectural challenges.
