Additive manufacturing (AM) methods are poised to become a cornerstone in the development of rapidly deployable architecture. This article explores the influence of AM technologies on the aesthetic qualities of fast-erected buildings. It examines the transformation of architectural concepts of form, materiality, and texture under the influence of 3D printing and robotic construction. Drawing on theoretical research and realized projects, the article proposes a conceptual framework for a new architectural language in modular construction shaped by AM. Special attention is given to architectural movements fundamentally impacted by 3D printing, including parametricism, morphogenesis, and object-oriented ontology. Additionally, the study investigates the potential alignment of AM technologies with phenomenological approaches in architecture and art. Unlike research that focuses purely on technological dimensions, this paper examines how AM can be integrated with phenomenological design principles, offering new strategies for sensory-centered design.
