SYMPOSIUM 15: 11th International Symposium on Additive Manufacturing and 3D Printing Technologies

Additive manufacturing (AM) and 3D printing technologies are globally recognized as novel fabrication processes for advanced materials and components with multifunctional structures. These technologies offer tremendous potential for design innovations and customization, complex part fabrication with multifunctionality, rapid prototyping, and distributed digital manufacturing. In this approach, three-dimensional models are designed and created according to theoretical concepts using computer software, and two-dimensional cross sections are created by slicing operations automatically. In direct writing processes, paste materials with ceramic/metal particles dispersed in binder system are fused from nozzles moving freely in three dimensions to create composite structures. In laser-based approaches, high resolution laser beams are scanned on a spread ceramic powder bed with or without resin binders to form solid planes of two-dimensional cross sections. Various functional components of dielectric lattices to control electromagnetic waves, bio-materials components for medical applications, and ceramics electrode with large surface area could also be developed. Large scale structural components for aerospace and other high temperature applications can be fabricated with internal cooling path networks formed without casting molds. Utilizing smart additive manufacturing, it is possible to design for function and not for manufacturing. However, each technique needs special design adjustments to boost products’ efficiency and multi-functionality.  This symposium focuses on superiority of design, efficient processing, and perspicuous evaluations in additive manufacturing and 3D printing processes. In addition, various topics related to starting materials, characterization tools, NDE and in-situ monitoring of processes, qualification and certification, cost, and applications will also be discussed.  

A special session is planned to focus on characterization and qualifications of ceramic feedstocks. The goal is to bring together researchers, industry practitioners, and standards developers to address the state-of-the-art in feedstock characterization and identify pathways toward qualified materials for ceramic AM.
