3D-printing catalytic applications

Tue, 06/27/2017 - 15:57
Three-dimensional (3D) printing, also known as additive manufacturing, is a fabrication method that creates structures from digital models. Unlike conventional fabrication methods, 3D printing processes are bottom-up fabrication methods which are based on the incremental addition of layers of materials. Recently, 3D-printing has also been shown to be advantageous to catalytic applications since a printing approach can achieve better control of the fine structure of the target material. It is expected that 3D printing fabrication will provide new solutions for preparing catalysts with new structures in a more economical and energy-efficient way.
