Course description

Ceramic additive manufacturing has advanced rapidly in the past two decades and continues to evolve as an industry. Currently available manufacturing systems present a viable alternative to some and a valuable complement to many more conventional manufacturing methods. As with any new manufacturing tool, quantifying and managing uncertainty and risk are crucial, necessitating a solid understanding of the scientific fundamentals as well as the technological state of the art. The course provides its audience a balanced program that contains a mixture of fundamental, economic, application-specific, and technology-based topics from a variety of academic, industrial, and government laboratory experts. The course includes the following topics spread across two days:

  • Day 1: General Overview, AM Methods, and Standards/Qualification
  • Day 2: Recent Advances and Horizon Technologies


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.

Learning outcomes

Attendees will get an introduction to the topic of additive manufacturing (AM) of ceramics and learn more about the economic and technical aspects of this field. Furthermore, attendees get an overview of state-of-the-art production methods as well as a deeper insight into the opportunities and limitations of the various technologies.

Title:  A Crash Course in Sintering Powder-Derived Ceramics, with a Focus on Additive Manufacturing

Additive Manufacturing (AM) of ceramics encompasses a wide variety of new forming techniques, but (nearly) always comes back to classic methods of thermal sintering for densification. This session will serve as an introduction for those new to ceramics and a refresher for those experienced in the art. We will start with the importance of solids loading and particle morphology, focus primarily on thermal processes of binder burnout and sintering, and discuss methods for interpreting microstructures to appropriately modify sintering schedules for desired microstructures. Oxides and non-oxides will be discussed. The intent is not for attendees to be sintering experts by the end of this brief session, but instead to understand the basics, know how to approach sintering challenges, and be able to find and understand appropriate additional resources as needed.

Title:  Current Status of Standards Development for Ceramic AM

Ceramic additive manufacturing (AM) processes are complex, multi-step, and cover a multitude of techniques that can include material extrusion, material or binder jetting, VAT photopolymerization, and hybrid casting.  These AM techniques are highly disparate in the types of feedstock and post-processing steps required to print a ceramic part.  As a result, progress in standards implementation has been slow compared to metal and polymer AM.  Recently ASTM and ISO efforts have been initiated with the goal of focusing more activity on ceramic-specific AM standards.  These efforts include the ASTM additive manufacturing committee (F42) ceramic materials task group (F42.05.05), ISO additive manufacturing technical committee (TC261), and joint ceramic materials task group (TC261/WG2/JG82).  I will discuss the status of ceramic AM standards in these committees and lessons learned from an ASTM-backed, NIST-led pilot round-robin study of mechanical properties in AM ceramics.

In this presentation, we will discuss the following topics:

  • The key benefits of XJet's technology for the production of high-performance ceramic parts
  • How XJet is dispelling the misconception of AM as a prototyping technology

Title: Current and Future Directions in Additive Manufacturing of High-Temperature Structural Ceramics

Abstract: Research in the field of ceramic additive manufacturing (AM) has been rapidly accelerating in the last decade, resulting in hundreds of publications and review articles on the topic. While strides have been made in forming near-net and complex-shaped ceramic components, challenges remain that inhibit more widespread implementation. Here, a brief analysis of the recent trends in the field as well discussion on types of AM methods, along with advantages and remaining challenges for each, will be given. A more detailed discussion on the topics of incorporating fiber reinforcements and implementing artificial intelligence (AI) approaches to accelerate feedstock development and process optimization will be presented. Focus will be given to current and potential future directions in each of these areas, both from recent literature reports and work conducted at the Air Force Research Laboratory.
