Material class-independent 3D printing of multifunctional components

Multifunctional products that meet the demands of an increasingly complex world require innovative manufacturing processes. These must enable high component geometry and the use of the optimal material in each case. With additive manufacturing (AM) technologies, such required degrees of freedom in the geometric design of real products and components can be realized. However, most AM technologies can only process one material class at a time – such as metal, plastic or ceramic. Certain material classes, on the other hand, cannot be processed at all.

Therefore, the Multi Material Jetting (MMJ) 3D printing process was developed at Fraunhofer IKTS, which enables the sustainable production of functionalized multi-material components in one printing process. This novel process is currently being commercialized with support from the EXIST research transfer program. The future startup will be able to offer customers industrial 3D printers as well as corresponding materials as early as 2023.

To make your multifunctional products feasible for you, we are looking for you as a pilot customer. Visit us at the ceramitec special show as well as at booth 319/420, hall C1!

Transparent Ceramics

Optical technologies are drivers of innovation and growth. For years, Fraunhofer IKTS has been a world leader in the production of transparent ceramics with a particularly fine crystalline structure and extremely good mechanical properties. This gives them significant application advantages over glasses, especially in harsh environments (e.g. temperature loads and gradients).

At Fraunhofer IKTS, research and development of high-purity transparent ceramics for optical systems, medical technology and ballistic protection is being steadily expanded. An equipment infrastructure based on PERLUCOR^® is currently being integrated, enabling the complete value chain for transparent parts and components to be covered. The new research and development center will help to significantly expand the current application scenarios of transparent ceramics with mature technologies.

Quality assurance: Inline inspection in real time

Until now, there has been no satisfactory automated solution for inspecting components – from green bodies to sintered material. A fast, non-destructive and inline inspection method developed at IKTS detects defects in high-performance ceramics early in the manufacturing process.

The sensor concept based on Laser Speckle Photometry (LSP) is used to non-destructively determine near-surface defects in technical ceramic components. The small and robust setup is characterized by low costs and a very fast measurement: depending on the resolution and computing technology, a component of size 30 x 30 mm², for example, is inspected in 60 seconds. Almost all common materials, such as Al₂O₃, TiO₂, ß-Al₂O₃, MgO or SiC, can be evaluated for defects in the material but also regarding their porosity.

Component and process visualization with augmented reality

To ensure that IKTS developments meet customer needs, are adapted to the specific application and can be operated intuitively, visual models are used via virtual reality in the development process. Augmented reality data goggles (mixed reality) can be used to demonstrate interaction and operation methods even before physical production and, if necessary, to point out and solve problem areas in advance.

Furthermore, operating instructions can be shown directly with the help of a digital twin, which enables ambidextrous work or virtual training scenarios. In addition to operating instructions, work-relevant data and information such as control cycles or inspection instructions for maintenance work can be displayed.
