Recent Advances in Multi-Material 3D Printing of Functional Ceramic Devices

Abstract

In recent years, functional ceramic devices have become smaller, thinner, more refined, and highly integrated, which makes it difficult to realize their rapid prototyping and low-cost manufacturing using traditional processing. As an emerging technology, multi-material 3D printing offers increased complexity and greater freedom in the design of functional ceramic devices because of its unique ability to directly construct arbitrary 3D parts that incorporate multiple material constituents without an intricate process or expensive tools. Here, the latest advances in multi-material 3D printing methods are reviewed, providing a comprehensive study on 3D-printable functional ceramic materials and processes for various functional ceramic devices, including capacitors, multilayer substrates, and microstrip antennas. Furthermore, the key challenges and prospects of multi-material 3D-printed functional ceramic devices are identified, and future directions are discussed.

Nozzle Innovations That Improve Capacity and Capabilities of Multimaterial Additive Manufacturing

“…Several single-material AM techniques have been modified to incorporate multiple materials, including direct-ink writing, fused deposition modeling, material jetting, stereolithography, and digital light processing, among others . Through this collection of techniques, virtually any combination of material classesmetals, ceramics, or polymerscan be processed. , Recent reviews have focused on MMAM developments for specific applications, − for specific materials or material properties, − and for specific AM techniques. − …”

Straightforward Design Strategy toward 3D Near‐Net‐Shape Stoichiometric SiC Parts

“…[10] It has recently renewed the vision of designing objects by giving access to new and complex architectures and topologies of materials such as plastics, metals, or ceramics which cannot be achievable by more conventional manufacturing technologies. [11] AM of SiC is a hot topic: [12][13][14] because SiC cannot be cast or machined easily, AM would enable a big leap in geometrical flexibility by considering that SiC is best suited for complex and advanced parts. Thus, different strategies can be envisioned such as stereolithography, [15,16] direct ink writing (DIW), [17,18] gel casting using 3Dprinted polymer skeleton, [19] selective laser sintering (SLS), [20] binder jet printing, [21] and extrusion-based AM technologies.…”

Development of TiO2/ZrO2 Multi-Material Obtained from Ceramic Pastes for Material Extrusion

“…The MEX can be employed to produce ceramic multi-materials [27,28]. This technology does not have some limitations that are inherent to other AM methods of producing ceramic multi-materials [29]. For example, other methods may have problems with changing the chemical composition of the material within a single layer (for binder jetting and VT).…”
