Single shell photopolymer skin

Monocoque stands for a construction technique that supports structural load using an object’s external skin. Contradictory to the traditional design of building skins that distinguishes between internal structural frameworks and non-bearing skin elements, this approach promotes the heterogeneity of material properties.

Monocoque’s structural skin is generated using a Voronoi pattern, the density of which corresponds to simulated loading conditions. The distribution of shear-stress lines and surface pressure is embodied in the allocation and relative thickness of the vein-like elements built into the skin. The prototype model was 3-D printed using OBJET’s Polyjet matrix technology which allows for the assignment of structural properties to multiple 3-D printed substances. This innovative technology provides for the ability to print parts and assemblies made of multiple materials within a single build, as well as to create composite materials that present preset combinations of mechanical properties.
