The work considered and presented in this thesis was catalysed by the potentials of the additive fabrication processes, usually referred to as Rapid Manufacturing. These fabrication methods connect its theoretical assumptions to its designs. The thesis was developed around a number of designs which were progressed in conjunction with its evolving theoretical components, the latter which entailed the formation of a bespoke taxonomy and accompanying bespoke terminology to describe the various distinct features and processes involved. The thesis questions the current detrimental schism dividing the act of computing based designing from the act of making something physical, and makes a case for a more inherent role for the material, sensory and tacit properties in the process of designing something through Rapid Manufacturing.
