// Fabrication Process As it is always an integral part of the CRAFT programs, analogue and digital would be incorporated again, and the fabrication process is tailored around the needs and necessities of the project. Thus making relevant tools, and development of the techniques are part of the work, parallel to the design development. In this year’s fabrication strategy, robotic arm (Kuka kr 150-240-2) is used to wire cut the polysterene foam pieces which will be the core of our sandwich strucured composites for this year’s pavilion. Bottum-Up design strategies focused on fabrication method are followed during the design process. This is helping to fabricate more complex products, where in combination with the material system of the project, is leaded towards the realization of the Customized Robotically Fabricated, Sandwich-Structured Composites. // Subdivision Process The hot-wire tool that we used was 100 x 100 cm therefore we used 50 x 50 x 100 cm blocks of polystyrene foam and then subtracted them using the hot wire to get to the final pieces that were needed. So we had to make sure our pieces had a bounding box less than that and also we had to minimize the number of pieces for fabrication and assembly ease. In addition to that we had make sure the cutted surfaces are also ruled. For that purpose we used isocurves of original surface and an evloutionary algorithm with the objectives of minimizing the number of pieces and also checking every output with the bounding box to make sure they fit in it.
