Additive Manufacturing of Ceramic Materials

Additive manufacturing of ceramic materials harnesses layer-by-layer fabrication to produce components with intricate geometries, tailored porosities and customised functionalities. By combining ceramic powders or preceramic polymers with energy sources such as ultraviolet light or laser beams, processes including stereolithography, powder-bed fusion and jetting techniques can generate near‐net-shape parts that would be impractical or impossible to form by conventional means. Key challenges remain in achieving full densification without cracks, controlling shrinkage during sintering and managing anisotropy in mechanical performance. Advances in feedstock formulation—through optimised dispersants, coupling agents and photoinitiator systems—have improved rheology and green part integrity. Post-processing steps such as debinding, pyrolysis and high-temperature sintering are refined to preserve dimensional accuracy and enhance strength. The evolving toolkit of additive techniques now spans from submicrometre feature sizes in projection micro‐stereolithography to robust, freeform architectures via aerosol jet printing. Ceramics produced by these routes find applications in aerospace thermal protection, biomedical implants, catalytic reactors, microelectronics and energy harvesting. The global significance of these developments lies in reduced material waste, shortened lead times and the capacity to integrate multifunctional features directly into ceramic devices, signalling a transformative shift in advanced ceramic manufacture.

Technical terms

Additive manufacturing: A suite of techniques that build components by depositing material layer by layer under computer control.

Photopolymerisation: A process in which liquid precursor resins solidify upon exposure to a light source, typically ultraviolet, to form a crosslinked ceramic–polymer network.

Stereolithography: An additive method that uses a scanning laser or projected light to cure successive layers of photocurable slurry or resin.

Aerosol jet printing: A direct-write technique that aerosolises nanoparticle inks and focuses them through a nozzle to deposit fine features without support structures.

Sintering: A thermal treatment that densifies ceramic or polymer-derived parts by driving out binders and promoting particle coalescence.

Anisotropy: Directional variation in material properties, often arising from layer-by-layer fabrication or non-uniform shrinkage.

Preceramic polymer: A polymeric precursor that converts to ceramic material upon pyrolysis, enabling complex green shapes to be transformed into ceramics.

Microlattice: A lightweight, architected structure composed of repeating unit cells, offering high strength-to-weight ratios and customisable mechanical properties.
