In mathematical analysis, Filling curves are characterized by their intricate geometric patterns, and employ recursive algorithms to intricately traverse and fill higher-dimensional spaces, ensuring comprehensive coverage of all points within the defined region- The fractal geometry that defines the lines of the filling curves (simultaneously aesthetic and structural) is a paradigmatic example of how to take advantage of generative algorithms, respecting their rules and enhancing their genesis. Creating a line that fills space automatically generates an organic and infinite path that guides the extruder of the robotic arm toward a formal conception that merges form with function. The lines serve as the input; however, the output leverages the materialization of curves into surfaces, which are more high-tech, crystalline, or organic, composing tables or lamps. Each selected recycled material follows the formal matrix and explores the substance that gives body to the design piece in a unique and distinctive way.
