The packed-bed reactor is one of the principal employed reactor types within the chemical industry. In essence, they consist
of a long tube either randomly filled with small packing elements or well arranged with structured packing parts. The
geometry of the packed parts strongly influences fluid dynamics as well as heat and mass transfer and thus the efficiency of the
reactor. However, the currently used production techniques for the packing parts are very limited in terms of achievable shape
variability. Therefore, the applicability of 3D printing as a supplementary production method is investigated, as 3D printed
parts can be of hardly any imaginable geometry. Shape optimization is performed following a sequence of simulation methods
coupling discrete element method with computational fluid dynamics. Inert prototypes can be printed and tested in known
testing units to predict efficiency increase. However, printing of catalytically active parts having both significant porosity and
sufficient stability is the challenge to be solved in future.
