Surface treatment techniques enhance properties like texture and wettability, crucial in manufacturing for years. The demand for complex, high-performance components has grown, leading to a need for multi-functional surfaces. Traditional methods, however, often involve environmental risks and inflexibility due to specific hardware needs. Laser Surface Texturing (LST) offers a more eco-friendly and versatile approach. Techniques like Direct Laser Writing (DLW), Laser Induced Periodic Surface Structuring (LIPSS), and Direct Laser Interference Patterning (DLIP) create complex surface textures with different-sized features, improving functionality. These methods achieve varying resolutions, from 200 µm in DLW to as fine as down to 10 nm in LIPSS, adapting to diverse industrial needs.

The SYNTECS project is focused on developing and demonstrating a versatile, cost-effective method of laser texturing to produce multi-functional surfaces on various products, including hip implants, injection molds, and vapor chambers. This initiative involves an innovative Laser Surface Texturing (LST) machine, equipped with both short and ultra-short pulsed laser sources. The machine is designed with a versatile LST texturing module, allowing for processing speeds up to 6 cm²/s. A specialized process monitoring system is also being developed. This system uses acoustic and optical emissions to maintain an optimal distance between the machine's head and the surface being processed. It also integrates an AI framework for detailed characterization of surface textures, ensuring high precision and quality in the texturing process. The SYNTECS project aims to reduce the time and cost involved in surface processing of hip implants, improve cooling efficiency in vapor chambers, and extend the life of injection molds. Overall, SYNTECS aims to boost the global competitiveness of European manufacturing by introducing these innovative surface texturing technologies.
