This 2’x2’ window screen prototype is designed to filter light through its organic porous structure. The panel thanks to its sculptural qualities casts shadows that activate the interior space, while the red filters embedded within it refract the light. As part of the assignment it was essential to find the right fabrication method to achieve desired lighting effect. After multiple grasshopper iterations, we chose to 3D print the lens. Due to the fabrication constraints imposed by the Makerbots the screen was divided into 13 smaller panels which were then assembled together. The final structure is a singular piece of a bigger system that could be mass produced and applied to larger surfaces.
