Smart surface functionalization by laser-made micro and nanostructures is a suitable tool to maximize the value of a product and enable new properties for common materials. Despite the recent progress, the capacity to produce micro and nanoscale surface features over large areas represents a significant challenge in terms of production technology, throughput and cost, especially for components with a complex 3D geometry. In this work, we introduce multi-beam technologies able to efficiently micro/nanostructure metallic moulds with the ability to transfer micro/nanoscale morphology to complex 3D polymeric components via mass production techniques such as injection moulding. Moulded samples with replicated structures demonstrated advanced functional properties, including increased contact angle by 27°, bacteria reduction by 99.8% and decreased friction coefficient by 66% compared to the reference sample.
