Additive Manufacturing

Additive Manufacturing (AM) is a revolutionary set of near-net- shape manufacturing technologies. Many different manufacturing methods have been established, from powder sintering, plasma jet deposition, extrusion, screen/ink-jet/aerosol printing, to just name a few. However, recent, accelerated widespread industrial adoption

of AM represents a significant milestone. The research and development of AM has moved the industry from polymeric prototyping of complex parts to the application of structural metallic and composite components with complex geometries that cannot be produced by forging or casting. Two areas of increasing importance are the application of AM to produce unique bio-mechanical devices of complex structures and materials, and flexible electronics. Electron- IC circuits can be printed (rather than etched/reductively manufactured); enabling them to flex and stretch.

There are several intersections between AM and the surface and coatings industry that are of common interest to researchers and practitioners of these communities:

  • AM components often require surface treatments to achieve their final functionality and optimizing the overall design and manufacturing process that utilizes the appropriate choice of the wide range of coating and surface modification processes will ensure improved
  • AM components frequently exhibit interfaces between similar or dissimilar materials, and proper interface and surface engineering are essential to successful component
  • Plasma-based processes are eminent in many AM manufacturing methods, and many process/structure/property interactions have been extensively studied in the plasma surface treatment and coating
  • AM also presents challenges to AM equipment suppliers as they expand the requirements of reflective/transmissive/focusing optics for laser/electron beam generation, direction and control. As the AM platform expands into more complex alloys and metals the duty will fall on the optical coating, laser and electron beam manufacturers/suppliers to keep pace with industrial demand.

This session/TAC seeks to bring together experts from the AM and thin film/surface engineering communities to discuss challenges and possible solutions in common areas of interest in an effort to further the successful adoption of AM in industrial applications

by leveraging the deep knowledge that resides in the surface engineering and thin film coating community. Contributions that highlight particular challenges or constraints as well as talks that highlight key operating principles of AM and their relation to coating and surface engineering aspects are particularly welcome in the interest of encouraging lively discussions.
