plattenbau216 ::: the prototype shown is the result of an ongoing research in parametric modeling and digital fabrication. The images depict the process from modeling to fabricating to assembling a 1:10 scale model of an architectonic structure generated in a parametric design environment and fabricated using laser cutting technique. For the realization of such structures, a custom fabrication software was developed allowing for the automated detailing of intersections of interlocking pieces and generation of fabrication documents. Searching to combine formal freedom with economical and production constraints in architecture, aim of the research is to translate complex formal geometries to simple construction techniques. The shelter prototype consists of 216 irregular interlocking pieces forming a periodic cellular pattern enveloping a free-form volume. It is constructed entirely of sheet material, wooden boards, detailed with plug-and-socket joints.
