Nowadays, 3D printing or additive manufacturing has been applied to a variety range of materials, from polymers, metals to ceramics. Within the 3D Matter Made To Order (3DMM2O) cluster of excellence, our focus is to characterize and understand the local structure and functional properties of 3D printed organic and inorganic materials and devices. By employing the state-of-the-art analytical electron microscopy techniques in combination with in-situ and ex-situ stimuli, we aim to provide insights into these 3D printed metamaterials in atomic, nano and micro scales, facilitating the tailoring of novel materials and devices in a bottom-up manner.
