Are you exploring what is going on with additive manufacturing techniques? Whether you are an engineer or scientist working in a national lab, on a factory floor, or on a college campus, then this is a great opportunity to learn what is going on in the industry, as well as the forecast of what is to come in a one-day short course taught by leaders in additive manufacturing. The course will cover technology overviews, as well as a look at the different aspects of manufacturing applications and markets.
|Course description and learning outcomes|
Ceramic additive manufacturing has the potential to radically change the market. The available manufacturing systems for ceramic have reached an advanced stage already and present a real alternative and a sensible addition to conventional manufacturing methods. This tendency of development has awakened great interest in industry and research, but also great uncertainty. It is therefore necessary to offer a deep insight into the subject to uncover the potential of the technology. This one-day course addresses the diverse technologies that are included in ceramic additive manufacturing with primary focus on methods that have reached commercial production – 3D printing/binder jetting, extrusion technologies, and lithography-based processing.
Students will learn and gain a basic understanding of
– the operating principles and process function of the various methods
– the design, size, and property capabilities and limitations of the different methods
– the importance of ceramic processing science throughout each of the AM processes
– the technical and market challenges, limitations, opportunities, and forward view of ceramic AM in industry

Presentation: Mass production with Additive Manufacturing: Pros and Cons
Through continued focus on innovative technologies, Johnson Matthey (JM) has developed the capability to 3D print ceramics using a binder jet technique. This presentation details JM’s 10-year development journey from the initial R&D scoping exercises, through prototyping, to full scale production in JM’s newly commissioned facility. During this process a number of barriers have been encountered which have had to be overcome. The presentation will also detail case studies of how binder-jet technology can be used to enhance product performance. From lightweighting parts used in the aerospace industry, to the optimization of fluid flow via in the design of complex catalyst supports and the use of customized components used in medical applications; this technology has a lot to offer.

Presentation: Additive Manufacturing of Ceramic Components by Ceramic On-Demand Extrusion (CODE)
An extrusion-based additive manufacturing process, Ceramic On-Demand Extrusion (CODE), known for producing ceramic components with near theoretical density will be introduced. In this process, an aqueous ceramic paste with high solids loading and low binder content is extruded on demand at a controlled flowrate through a positioning nozzle to fabricate a 3D part layer-by-layer. After each layer is completed, it is surrounded by oil filled to a level just below the top surface of the deposited layer, and then infrared heat radiation is used to uniformly dry the layer. Sample alumina parts produced using the CODE process demonstrate its ability to fabricate monolithic ceramic parts of complex geometry. Mechanical properties of these parts (after sintering) will be compared to those produced by several existing ceramic additive manufacturing processes.

Presentation: Perspectives on Additive Manufacturing of Ceramics via Robocasting
A revolution or cool useless parts? A perspective of 3-D printing of ceramic materials will be presented in general and more specifically for a technique known as robocasting.
Robocasting is a specific subset of extrusion-based AM techniques utilizing concentrated fine-particulate pastes carried in a volatile solvent medium. Removal of the solvent transforms the paste into a solid-like state thereby “curing” the particulate assemblage and facilitating the creation of components. Relationships between inter-particle forces and rheology which facilitates robocasting will be introduced.
Robocasting is particularly suitable for commercial-scale manufacturing of porous lattice structures for filtration of molten metals, catalyst supports, and load-bearing hydroxyapatite bone scaffolds. The character and performance of these structures will be reviewed.
Considerations for designing parts most amenable to robocasting will be discussed as well as the advantages, disadvantages, limitations, and future challenges of robocasting.
