NEW DATE: Due to COVID-19 (Coronavirus) the Ceramics Expo has been posponed to September 22-23. The new day for the Short Course will be September 21.
Learn how ceramic additive manufacturing can be an alternative to conventional manufacturing methods
Monday, September 21, 2020—8:30 a.m.–4:30 p.m. | Cleveland Airport Marriott, Cleveland, Ohio | Held in conjunction with Ceramics Expo 2020
Lead Instructor: Shawn M. Allan, vice president, Lithoz America LLC
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. The course provides its audience a varied program which contains a mixture of economic, application-specific and technology-based topics. The course includes the following topics:
- Session 1: General Overview
- Session 2: Technology Overview
- Session 3: Manufacturing, Applications and Markets
The course is specifically suitable for people from the fields of company strategy & development, research and development, universities, construction, design, production, supply chain management, product development, and innovation development.
Attendees will get an introduction into the topic of additive manufacturing (AM) ceramics and learn more about the economical and technical aspects of this new technology. Furthermore, attendees get an overview of state-of-the-art production methods as well as a deeper insight into opportunities and limitations of the new technology. Attendees will also gain a basic understanding of how to implement AM systems into their production chain, and learn what kind of applications are recommended for additive manufacturing. By the end of the course, attendees will understand the pros and cons of different technologies and will be able to use their gained knowledge in the strategic planning.

Introduction and Course Objectives
The term "additive manufacturing" covers a wide range of technologies, each suited to a range of applications, materials, part sizes, and forms. The scope of additive technologies and particularly those relevant to ceramics will be addressed.
Bio: Johannes received his master’s degree in industrial engineering at Vienna University of Technology in 2005, and finished his Ph.D there in 2008. He has been teaching since 2009 at different universities, and is the co-inventor of three patents. Homa is the co-founder and CEO of Lithoz GmbH. Lithoz GmbH is based in Vienna, Austria and is the world leader in additive manufacturing of high-perfomance ceramic components.
Key Drivers for AM Ceramics
This contribution focuses on the key drivers for a successful implementation of AM and it highlights how to find the “real” AM applications. Showcases will demonstrate the potential of AM by highlighting improved designs that are enabled by AM and correlating new applications.
Lithography-based Ceramic Manufacturing (LCM-Technology)
Lithography-based ceramic manufacturing (LCM) is a slurry-based process that relies on the selective curing of a photosensitive ceramic suspension. LCM enables the production of precise ceramic parts with the same material properties as conventionally formed ceramics.
Bio: Blacker is product development manager and principal investigator at ExOne. He has a bachelor's degree in mechanical engineering from the University of Cincinnati and has served as senior program manager and technical principal investigator for numerous advanced materials research and development programs for both government and commercial customers, including numerous SBIR programs. Blacker is leading ExOne’s new material development efforts in the areas of ceramics, carbon, and refractory metals. He is currently principal investigator on a three-year, $1.5M contract with the U.S. Missile Defense Agency entitled “Three-Dimensional Printing of Silicon Carbide for Optical Structures."
Binder Jetting Additive Manufacturing of Ceramic Materials.
Blacker will review the current state of the art in terms of binder jetting machine capabilities as it relates to ceramic powder printing, as well as discuss applications of binder jetting AM for ceramic materials.
Bio: Cesarano is currently the President of Robocasting Enterprises LLC and serves on the Board of Trustees for Alfred University. He received a BS Suma Cum Laude in Ceramic Engineering from Alfred University in 1983 and an MS in Ceramic Engineering and PhD in Materials Science from the University of Washington in 1985 and 1989 respectively. He has been a Visiting Scientist at Oak Ridge National Labs and the Swedish Ceramic Institute. From 1989 – 2007 he was a scientist with Sandia National Laboratories and served as an adjunct professor in the Department of Chemical and Nuclear Engineering at the University of New Mexico and in the Department of Materials Science and Engineering at New Mexico Tech.
In 1999, Robocasting Technology was noted as one of the 50 notable achievements in the fifty-year history of Sandia National Laboratories. Robocasting publications have been featured cover stories for the Ceramics Bulletin, the Journal of Applied Ceramic Technology, and Langmuir. In 2002, robocasted lattice structures was selected as one of the nine most interesting materials achievements by Chemical & Engineering News.
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.
