The replica technique is one of the most established manufacturing methods of highly porous scaffolds for bone tissue engineering. Despite a multitude of possible templates, this method is limited in terms of reproducibility and periodicity. We overcome this issue by 3D-printing of designed periodic polymer templates which we further process with the replica technique to obtain cellular ceramics with adjustable micro- and macrostructure. The periodic structure (Kelvin cells) was created using a computer-aided design (CAD) software changing the strut shape and thickness. The structures were 3D-printed with rigid polymer and afterwards processed with the classical replica technique. The combination of polymer 3D-printing and the replica technique brings us one-step closer to the excellent replication of cellular materials.
