Editorial on the Special Section of CELLMAT 2022

Cellular materials are an established field of research, often driven by applications. Manufactur-ing issues traditionally play a significant role in such established topics. New manufacturing pro-cesses frequently create cellular structures, and the question of the industrial usability of these techniques remains a key concern for the community. The boundaries between traditional mate-rial classes often blur, as manufacturing processes can be applied to a wide variety of materials. This trend is exemplified by the ongoing use of additive manufacturing methods, particularly in the production of highly porous materials. The contributions published in this special section are selected works presented during the CELLMAT 2022 conference, highlighting the advancements in eco-friendly and sustainable techniques in the field of cellular materials.
