3D printed catalytically active devices in organic synthesis

Three-dimensional (3D) printing is a technique characterized by sequential deposition of different materials in a layer-by-layer approach for the construction of objects starting from a virtual design. The use of 3D printing technology in chemistry is becoming popular, but its potential has not been fully exploited yet. The objective of this survey is to describe the most important examples of catalytic functionalized 3D printed devices employed in synthetic transformations. For each example, the 3D printing technology used and significant results are highlighted.
