Elective course on robotically extruded structures. The ABS extruder is mounted on a UR robot and allows us to generate different spatial structures. In this work has been used a Voronoi subdivision of a given geometry. The point generation inside the main polygon is controlled and can be affected by attractors (e.g. lines) that increase the points number. The spatial development is controlled by a Python script and can consider different criteria to define the points position along the Z axis.
