Overview of Ceramic Additive Manufacturing

There are many platform choices for Additive Manufacturing (AM) of ceramics, and it is important to understand how these different methods may impact the final product. AM is typically thought of as a forming process in ceramics. Ceramic properties can be extremely sensitive to forming method, and are affected by variables such as particle size, morphology and packing, organic additive type and quantity, as well as stresses applied during forming. This talk will identify the platforms and methods available for AM of ceramics and explain how they work. The advantages and limitations will be discussed, to enable down selection of the appropriate platform for specific applications. Finally, some thoughts will be shared on areas for advancement and future direction of Ceramic AM.

Ceramic Additive Manufacturing: Markets & Industries

Additive manufacturing (AM) for advanced ceramics is becoming increasingly used in several areas. As can already be seen in more mature sectors such as metal and plastic, AM technologies can be beneficial to any industry, but success will always depend on identifying the right application in combination with the right technology. Lithography-based technologies are well suited for ceramic applications where high precision and accuracy are required in combination with mechanical performances similar as classical formed ceramic parts. This lecture will focus on industries which have recognized these advantages early on, such as the casting and medical sector and how pioneers employ the LCM Technology to develop innovative functional applications.

Bio: Cox is an R&D materials scientist at Honeywell Federal Manufacturing and Technologies, located in Kansas City, Mo. Recently completing an M.S. in materials science from the Colorado School of Mines in Golden, Colo., Cox’s current responsibilities include materials characterization, as well as working to develop ceramic AM capabilities at the Kansas City National Security Campus. During his graduate research, he studied extrusion-based AM of electrical ceramic materials with a focus on functional grading between medium and high permittivity electrical ceramics for use in dielectric resonators. Cox's talk will focus on a general outline of the work he performed and the challenges and lessons learned from his experience.

Extrusion-Based Additive Manufacturing of Electrical Ceramics: Lessons Learned

Dielectric resonators (DRs) are ceramic components used primarily in wireless communication devices for their high relative permittivities and low loss properties, with much room for improvement aimed at maximizing their electrical properties. Additive manufacturing (AM) of ceramic materials opens the door for new methods of fabrication of these DRs to produce functionally graded permittivities. An extrusion-based ceramic AM technique has been employed to print structures with graded permittivity and custom geometries. Through a series of rheological studies, shear thinning ceramic suspensions of titanium dioxide and barium titanate have been developed to demonstrate this technique and improve the ability to print such structures. Co-sintering studies were performed to ensure that these materials are compatible during densification and sintering, with validation through microstructural characterization, to verify that the essential material properties meet the requirements of these DR devices. Graded permittivity parts have the ability to enable new electrical properties of DRs, which can be used as a host of new opportunities in the field of microwave dielectrics, such as DR oscillators and DR antennas.

Challenges for industrialization of additive manufacturing of oxide ceramics—Insights from a user

CERIX – A Bosch Company has used the lithographic additive manufacturing process (LCM) since 2014. First, the idea was to use this technology to accelerate projects for our core technology ceramic injection molding. Bosch’s goal is to produce high quality series products. When we introduce a new technology, it must have the capability for mass production. Therefore we carried out a machine capability study according to Bosch automotive standards. Depending on the market segment, an additional validation process is often requested.

Since our experience with the lithographic additive manufacturing process began, many challenges have been solved based on this study and more opportunities are arising. Last year additional equipment using a larger platform was installed to fulfill the market requirements. Today we also run the equipment for series production.
We will present the principles of this study and some results about the best practices.

Within the Association of German Engineers (VDI), he contributes to the formulation of standards for the AM of ceramics, concerning technologies, materials and design rules.

Design for Ceramic Additive Manufacturing

Additive manufacturing of ceramics creates the possibility to manufacture extremely complex parts without the need for tools or the associated lead times. Nevertheless, like every manufacturing technology, AM has its own characteristic design rules, and combined with the well-known constrains of ceramics, a very particular set of design guidelines must be accounted for in the design phase. Fortunately, many of the design rules of these two aspects combine very well, offering an enormous opportunity for the ceramic industry. This talk will cover the challenges for AM in ceramics and will give examples on how to overcome them.
