At a 3D printer, participants discover what recyclable plastic can create and where 3D printers are used, with a short introduction to 3D design and the software used for complex projects. Together they then design a small object to take home. Conducted in German, children aged 8 and up take part accompanied by an adult. Places are limited, though joining a session in progress is possible.
