Permeable Halftone Wall

This system was inspired by the halftone reprographic technique, which consists of a matrix of dots with different sizes and spacing, which allows monochromatic printers to simulate tonal variation from a photograph or image. Molds were made as a series of seven units each containing a pin of different diameter in the center. The smallest size started at 1/2 inches, increasing in increments of 1/2 inches up to 3.5 inches diameter for the largest one. In order to obtain voids than run through the wall, molds were paired-up on both sides of the wall. The system used 3D printed inserts. The pins were tapered with a 5-degree angle to allow easier demolding. The mockup showcased seven units of different sizes that produced a pattern which increases in diameter as voids converge at the geometric center of the wall. An intrinsic characteristic of the system is that the molds offer the possibility to generate openings of various sizes creating perforated walls with different levels of permeability based on the distribution of the voids. This is particularly useful for visibility and light control. When the surface of the wall is large enough to accommodate a large number of units, actual images can be reproduced.
