The Picoroco Wall is constructed using the Picoroco Block™, a modular 3D printed building block for wall fabrication printed in PLA. PLA, or polyactic acid, is a thermoplastic aliphatic polyester derived from renewable resources. The wall is comprised of blocks with a dimension of 5.75″X5.75″X5.75″. Three different blocks are used in the construction of the wall—a 2, 3 and 4 hole block. Each block can be randomly rotated to create the variable pattern found in the wall.


The transparency of the material creates different layers of visual porosity. Figures moving behind the wall are revealed within the cellular geometry of the blocks.


The opposing side of the wall reveals the bumpy surface’s underlying geometry—a series of interconnected pentagons, hexagons and quadrilateral shapes whose terminus is a circle. Each block is connect by 3D printed clips of the same material that bind the corners of each block together making the wall easy to assemble and disassemble.


The variegated pattern allows for views to pass through in some areas of the wall, but not in others. The quality of light and shadow constantly changes across the surface with the passing of the day.
