This thesis investigates the relationship between digital fabrication techniques and the design constraints, such as function and materials, which are determined during architectural design processes by architects. This relationship is formulated through a matrix. Digital fabrication techniques are generally discussed upon and decided at the last step of a design process. This study roots from the idea that knowing which technique to use for fabrication affects the design process. In that sense, ‘according to which constraints which technique suits the design intention best’ should aid the designers. To propose a classification matrix two steps are practiced: first, as digital fabrication is a newly developing area, there are confusions, shifts, and overlaps of terminology among fabrication techniques; thus a simplification and classification in the terminology is needed. Such a classification is carried out in this thesis through recurrence tables based on a literature survey, the output of which constitutes the main column of the matrix. Secondly, a set of design constraints are determined by analyzing built projects, which are realized using specific digital fabrication techniques. This set of constraints establishes the columns of the matrix. The classification matrix aims to contribute both to educational and practical sides of architecture, proposing digital fabrication techniques to designers according to specific design constraints.
