The introduction of digital technologies for making models, prototypes, and buildings or building parts in the architectural research, teaching, and practice is a reality today. However, the process is sometimes jeopardized by the lack of clarity regarding the use of certain terms still found in the literature. The goal of this paper is to contribute for overcoming this flaw by providing such a clarification and a possible categorization of the available technologies. The term digital materialization is proposed as a general term to designate all the production technologies available for making physical artifacts.
