Abstract This collection provides an overview of current developments in the field of metallic hybrid and porous materials and components made of such materials. Hybrid materials have a locally defined varied material composition while porous materials feature an intentionally cellular material structure. Hybrid porous materials combine both a locally varying material composition and a porous structure. This collection was initiated by the DFG Collaborative Research Centre TRR 375 “Multifunctional High-Performance Components made of hybrid porous materials", which researches the design, manufacture, and characterization of these materials and components. In this collection, the additive manufacturing of hybrid and porous materials is highlighted and methods for the monitoring and control of the manufacturing processes and thus the control of the component properties are pointed out. In addition, approaches to determine the properties of hybrid and porous materials and the application characteristics of hybrid and porous components are outlined. The collection offers insights for those interested in manufacture, characterization, and applications of hybrid porous materials.
