Abstract
In order to reduce drag and improve the ecological impact of industrial components, the BILASURF European Project focuses on developing and integrating a method for high-speed laser functionalization of complex 3D surfaces using tailored designed riblets for each application, while ensuring a high production rate through inline monitoring features. The process will be demonstrated in hydro-turbines and industrial fans. As the size and period of the riblets depend on each application, a machine prototype has been designed and manufactured including two different technologies to cover a wide range of riblet periods: Direct Laser Interference Patterning (DLIP) for periods up to 44 μm, and Direct Laser Writing (DLW) for larger periods. A custom designed acoustic monitoring system, which tracks the focal plane position inline, helps in maintaining a high throughput throughout all the process.
