Over the past decades, significant advancements in manufacturing techniques have enabled the realisation of various types of metamaterials, ranging from conventional methods such as subtractive and formative manufacturing to disruptive approaches like additive manufacturing. This roadmap explores the current-state-of-the art manufacturing techniques for metamaterials, highlighting key challenges and opportunities in scaling up production and commercialisation. Structured around three metamaterial categories – mechanical, electromagnetic and acoustic – and three manufacturing approaches –additive, subtractive and formative – this roadmap presents insights from leading experts on the future of metamaterial fabrication, offering perspectives on overcoming barriers to large-scale implementation.
