AETHERIUS – A modular pavilion 3D-printed using recycled stone aggregates
AETHERIUS stems from a desire to demonstrate that architectural 3D printing can generate forms of great geometric complexity using materials with a low environmental impact. The pavilion is conceived as a modular structure printed by extrusion, whose mortar is composed of marble dust, stone and aggregates recovered from the stone industry. This approach tackles two issues simultaneously: the search for new applications for additive manufacturing on an architectural scale and the reuse of industrial waste that would otherwise end up in landfill.
The design challenge lay in reconciling an organic, fluid morphology (inspired by natural forms) with the technical constraints of the extrusion process. Each module had to be printable as a standalone unit and assembled sequentially, ensuring structural continuity and formal coherence. The large openings at the top are not an aesthetic gesture but a deliberate strategy: they allow natural overhead light and natural ventilation to enter, reducing the need for artificial lighting and air conditioning.
The most distinctive feature of AETHERIUS is the three-dimensional texture of the soffit, generated directly by the printing process. Rather than concealing the traces of additive manufacturing, the design transforms them into a spatial quality: the 3D-printed layers are enhanced by the interplay between natural light and the sinuous three-dimensionality of the structure. The integration of trees into the structure (which grow through the upper openings) dissolves the boundary between architecture and landscape, making the pavilion a hybrid organism between the built and the natural.
The project has been developed in collaboration with B&Y Srl and is conceived as a replicable prototype: the modularity of the system allows the configuration to be adapted to different contexts, from temporary installations to permanent public spaces. AETHERIUS demonstrates that 3D printing is not merely an alternative construction technique, but a design paradigm that allows for the simultaneous rethinking of form, material and process.
