Additive Manufacturing enables minuscule metal structures with a complex geometry to be produced. Here is a test piece compared with a match head. Using AI to monitor the manufacturing process acoustically guarantees that the workpiece is devoid of any interior defects. Image: Empa
Welding, printing, crushing concrete - an Empa team monitors noisy processes with the help of artificial intelligence. This way you can literally hear production errors and imminent accidents. Kilian Wasmer from the Empa lab for Advanced Materials Processing in Thun keeps shaking his head while speaking, as if he can't believe the success story himself. Together with his team, he recently patented a system to monitor complex production processes, which can be used in a vast range of situations - even though the prospects of this idea initially did not look particularly good at all. "I told our partners that I rated the chances of success at around 5%. But we'd still give it a go," recalls Wasmer about the project's early days. The aforementioned partner is Selfrag AG from Kerzers near Bern.
