Audi is recycling the plastic packaging used to deliver sensitive components to its Neckarsulm assembly plant in Germany and uses it to produce 3D-printed tools for vehicle production. According to the carmaker, the blister packaging, which is used to deliver such parts as sensors and speakers, is collected and sorted by type before being shredded and granulated to dry it out. A filament maker then heats the granulate up to 450°C and extrudes it in the form of plastic filament. That filament is the raw material for the 3D printers that the Neckarsulm team uses to produce precision-fit assembly aids for vehicle production.
