Description
Metal additive manufacturing (AM), especially laser-based powder bed fusion, enables the fabrication of components with complex geometries and high functional integration, but typically results in relatively rough as-built surfaces. Surface quality is especially critical for particle accelerator components, such as those subjected to radiofrequency, where skin effects become increasingly relevant when associated to uncontrolled surface roughness.
The contribution offers a survey of the main aspects of importance for the design of surfaces of copper parts produced by AM for LInacs. The desired requirements and the critical issues for achieving them in complex components are discussed. Reference to most recent research achievements in this field are made to demonstrate the key role of surface engineering and conditioning in enabling high-performance PBF-LB/M components for Linacs applications.
