digital primitive #2: iterative design
digital primitive - caterina tiazzoldi + eduardo benamor duarte

digital primitive extended is an installation that presents the work of a group of architects, designers and manufacturers in new york, representing a conceptual and productive reality in the city.

they are digital because they are the first generation of new york designers and architects graduated in a context characterized by digital modeling techniques and computer numerical control (CNC) manufacturing. they are primitive because they have to provide an answer to the limitations posed by a city like new york.

lúcio has been invited to present current research as part of the digital primitive installation in the cais do sodré underground metro station.

FACETED | FIBROUS | STRUCTURES is a research endeavor focusing on producing complex double-curved structural geometries using standard planar materials assembled together in linear strips. When a material is folded its bending strength is increased parallel to the fold. Using ancient paper folding techniques (origami) as inspiration, the concept of folding flat metal sheets allows one to triangulate geometries and generate long volumetric folded strips that can then be assembled together to create structural ribs.

The apertures and depth of the faceted system can be sized according to solar gain requirements as well as structural performance criteria and/or weight reduction necessity. Using standard CAD/CAM technologies, the folded strips can be easily manufactured from planar sheets using CNC, laser, or water-jet cutters.

Design of the FACETED | FIBROUS | STRUCTURES was developed in Rhino using Rhino Scripting. The structure is generated using a base surface onto which 3 layers of points are plotted. The top layer represents the exterior, the middle layer the center, and the bottom layer the interior. Surfaces are then created from the points using an elongated hexagonal pattern.


The XO.S | PAVILION is a formal exercise emulating biomorphic exoskeletal systems, intended to be used as a temporary place of gathering. It funnels pedestrians from one end to the other, compressing at the center and then widening at both ends dividing space into two zones. The pavilion is fabricated from stainless steel folded strips, laser-cut from flat sheets and welded together. The exterior is painted with a high-gloss black car paint finish while the interior and inner faces are painted white.
