ABSTRACT Carbon nitride has emerged as a versatile, metal‐free semiconductor, originally explored primarily for solar‐driven photocatalytic reactions. Its progression from a photocatalytic powder to a digitally processable, structurally adaptable material represents a significant step forward in modern manufacturing. Advances in colloidal control and interfacial engineering have transformed carbon nitride from a static catalyst into a dynamic design element compatible with diverse printing technologies, enabling spatially defined architectures that integrate reactivity, durability, and sustainability. This review summarizes the implementation of carbon nitride in microcontact printing, inkjet printing, fused deposition modelling, direct ink writing, and digital light processing, and discusses interfacial‐assembly–driven shaping in both all‐aqueous and heterophase systems. Together, these developments address applications beyond photocatalysis and summarize interest from diverse fields, from mechanics to bioengineering. Carbon nitrides are emerging 2D materials for printing applications, and this review critically investigates nanoscale parameters that govern digital fabrication principles for functional macrostructures.
