Replay (pyramid) investigates qualities of 3D manufacturing technologies and their potential to create unpredictable shapes.
The main part of the experiment consists of a computer generated pyramid. This pyramid is first produced with a 3D printer and then subjected to successive 3D scanning and 3D printing.
Each of these technical production steps result in significant modifications of the original form. For example: In the digital world, the tip of the pyramid is ideally represented by a single dot. However, the tip of the physical pyramid consists of a toric curl. Tiny gaps in the surface of the printed pyramid also lead to crumpled walls of its digital copy. Such resulting “mutations“ become visible in the form of five plastic pyramids that document the evolutionary process.
Some evolutionary stages reveal objects that do not correspond at all to their original form. Such objects are usually created by “faulty” 3D scanning processes that lead to completely unexpected figures. These elusive shapes exist only in the digital realm. Within the framework of a computer-animated video projection, they revolve constantly around themselves.
