Concretia is a revolutionary exhibit showcasing the avant-garde application of selective cement activation technology. This concept project, resembling an egg, leverages a sophisticated algorithm to generate points along the façade's kubature, intelligently connecting them based on rigorous performance criteria. 
The algorithm dynamically adapts, ensuring structural integrity and optimal spatial relationships. The resulting network of lines serves as a skeleton for the façade's volume, meticulously divided into fabricatable panels that adhere to construction and fabrication constraints. Concretia epitomizes the fusion of parametric design and cutting-edge technology, offering a glimpse into the future of architectural synthesis.

Synapsis is a 3D-printed screen with interlocking skeletons that functions as both a room divider and an object display. Its dynamic design allows users to create new configurations by moving the parts without touching, emphasizing functionality and exhibition.
This design, which takes its name from the synapsis stage of cell division, was first started by producing modules that resemble chromosomes. These modules have evolved into two different parts that can stand on their own with the least possible material. Thus, two 3d-printed skeletons that can stand on their own, intertwined but do not touch each other, were created.
Special thanks to Additive Tectonics and Bruno Knychalla, Managing Director, for their invaluable support and collaboration in advancing research on Selective Cement Activation technology. Their expertise and resources have been instrumental in exploring new possibilities for sustainable architectural 3D printing.
