Conducted in Pichincha, Ecuador, from October 15, 2021, to January 15, 2022, and November 16, 2022, to February 28, 2023, this exercise explored the co-design potential between humans, non-human entities, and machines. Using Rhino Grasshopper, we created an evolutionary algorithm to shape wax films for bee-integrated 3D printing. The iterative process depended on ecological timelines and environmental conditions, evolving with bees' natural behavior and climate factors. This approach emphasizes non-human-centric design, highlighting the roles of temperature, humidity, and flowering plant availability. While not for immediate application, this exercise speculates on future design with non-human entities, showcasing the synergy of digital, human, and biological inputs and promoting post-anthropocentric design practices.",

         "volume": "32","abstract": "In the 21st century, as free form design gains popularity, free-form grid shells are becoming a universal structural solution, enabling merger of structure and facade into a single layer - a skin [31]. The subject of the presented work is the optimization of grid structures over some predefined free form shape, with the goal of generating\r\na stable and statically efficient structure. It is shown how combining design and FEM software in an iterative, Genetic Algorithms based, optimization process, stress and displacements in grid shell structures can be significantly reduced, whereby material can be saved and stability enhanced.\r\nWithin this research, design and static analysis software are combined in order to perform a statical optimization of grid shells,generated over a given free form surface. A plug-in for Rhinoceros 3D (software based on NURBS [44] geometry representation) is developed, that uses Genetic Algorithms as an optimization method and implements automated iterative calls to Oasys GSA (commercial FEM static analysis software) in order to generate a statically optimal grid shell. To make this possible, within this research some new types of automatic grid generation are developed. Voronoi\r\ndiagrams [11] were used together with the adapted Force-Density method [38] to develop a new type of grid structure that we called Voronax. In the presented work it was shown that, using the same free form surface, and using the same number of joints and structural members, we can generate much more efficient grid shells,\r\nwhen compared to the standard (uniform) grid structures, simply by modifying the structural grid, i.e., rearranging the structural members of the grid shell.\r\nThe work presented offers an explanation of the entire method and how it can be constructed. The results of the experiments are there to prove its efficiency and credibility. Once it is proved that the method works, its application can take various forms and be left to the creativity of the user and the requirements of the\r\nspecific project.",
