Additive manufacturing is increasingly being used to develop innovative packings for absorption and desorption columns. Since distillation has not been in focus so far, this article aims to fill this gap. The objective is to obtain a miniaturized three dimensional (3D) printed packed column with optimized properties in terms of scalability and reproducibility, which increases process development efficiency. For this purpose, a flexible laboratory scale test rig is presented combining standard laboratory equipment with 3D printed components such as innovative multifunctional trays or the column wall with packing. The test rig offers a particularly wide operating range for column diameters between and . First results regarding the time to reach steady-state, operational stability, and separation efficiency measurements are presented using a 3D printable version of the Rombopak 9M. Currently, further developed and newly designed packing structures are being characterized, which should exhibit optimized properties especially with respect to scalability and separation efficiency.
