Abstract
Structured packings are important elements to enhance mass and heat transfer in the chemical industry. New techniques of manufacturing, like 3D printing, can create completely new families of solids used for this purpose. In this work the effect of different 3D printing techniques in the manufacture of packings with triply periodic minimal surfaces (TPMS) geometry was analyzed and the influence of different 3D printing techniques in the final properties of packings produced with TMPS topologies, both numerically and experimentally, were studied.
