Additive Manufacturing of Novel Hybrid Monolithic Ceramic Substrates

Additive manufacturing (AM) can revolutionise engineering by taking advantage of unconstrained design and overcoming the limitations traditional capabilities. A promising application AM is in catalyst substrate manufacturing, aimed at enhancement catalytic efficiency reduction volume weight reactors exhaust gas aftertreatment systems. This work addresses fabrication innovative, hybrid monolithic ceramic substrates using technology based on Digital Light Processing (DLP). The designs are two individual integrated into a single, dual-substrate monolith various interlocking These novel monoliths lay foundation for potential complexity expense system. Several examples systems dual were designed, manufactured thermally post-processed to illustrate viability versatility DLP process. Based findings, sintered parts displayed anisotropic sintering shrinkage approximately 14% X–Y direction 19% Z direction, with density 97.88 ± 0.01%. Finally, mechanical tests revealed integrity designed interlocks. U-lock Thread configurations found sustain more load until complete failure.
