Ten questions concerning the integration of digital fabrication techniques into the architectural design process

Recently, digital fabrication techniques have captured the attention of many architects and makers due to their ability to challenge traditional construction techniques and complex forms that were hard to apply in the past. Digital fabrication has bridged the gap between the architectural design and construction processes by creating a direct digital link to the appropriate fabrication machines. Nevertheless, integrating digital fabrication techniques in the architectural design processes is still a major challenge to creating a culture of digital building all over the world. In this regard, this paper has arranged 10 key questions and their answers with a particular focus on how to integrate digital fabrication techniques into the architectural design process. It provides an overview of digital fabrication concepts and processes, computer software, material selection, the most popular digital fabrication techniques and their architectural applications such as free-form geometries, façades design, buildings, bridges, pavilions as well as structures like columns, walls, and slabs, along with the most significant challenges and opportunities facing the widespread use of these techniques in architecture. In an effort to identify new research trends, this paper concludes by discussing the state of the art in architecture-related digital fabrication research and research potential gaps, which will be beneficial to further research and scientific investigations in this field. Hence, a conceptual framework is suggested as a guideline for numerous architects, fabricators, and researchers to follow for integrating digital fabrication techniques into the architectural design process in order to take advantage of this strategy at scale.
