3D-printed catalyst structures have the ability to widen reactor operating windows. Two dozen structural variations have been investigated at various operating conditions, and the measured transverse gas dispersion has been correlated to Péclet number and the structures' size; porosity; and feature size. Stacked versions of these logpile structures have a significant increase in tunability of the dispersion behavior compared to straight structures, according to reports.

Traditional concrete block building is slow, labour-intensive, and costly. 3D printing has a strong potential to assist engineers and architects in constructing fast and inexpensive yet complicated representational infrastructures. Printing concrete 3D printing in civil infrastructure is one of the most significant barriers to the widespread use of concrete 3D printing in civil infrastructure is the difficulty of fabricating printed structural components with reinforcement to ensure consistent structural results under different loading conditions. Hence, it is therefore necessary to produce concrete that can be used as a rebar-free material by considering strength and ductility. Engineered Cement Composite Composites' development has neared the possibility of achieving both strength and ductility in the concrete structures without embedding steel reinforcement. This scheme explores the production of ECC papers in Region 6 that utilize commonly available ingredients with rheological characteristics that are specifically designed for 3D printing applications.
