Emotive qualities of parametrically designed and 3D printed surfaces

Surfaces play a crucial role in design. Constituting a physical and visual interface of an object, a surface not only reveals important information about the identity of the entity it encloses but also determines impressions, evaluation, and expectations we have about the object. Despite their significance, surfaces have long been considered to be a subordinate part of form rather than an independent design element, especially under the reign of mass production. This paper challenges the conventional hierarchy and demonstrates a systematic and customisable process of creating purpose-specific, context-oriented surfaces which provide their own set of form and function.

Various digital technologies, including coded parametric modelling, geometric alteration, and 3D printing, were employed as main tools and thoroughly utilised across creation, modification and fabrication of surfaces. Through experimentation with software and mechanical configurations and materials, a series of high-resolution surfaces with different parameters were produced. Furthermore, the potential for direct digital manufacturing (DDM) and its practical penetration was investigated by producing all surfaces directly from an affordable desktop filament fused fabrication (FFF) 3D printer without the use of post-production processes, which provided an understanding of the restrictions and opportunities of the technology.

User testing was carried out over participants who observed and interacted through touch with each surface both blindfolded and without blindfold. With each interaction the user was asked to populate a questionnaire form that asks them to identify their interpretation of the surface on a spectrum. The questions were devised to explore three distinct areas of inquiry geometry, physical properties and emotive responses. The results were then analysed using the method of design of experiments (DOE) in order to identify parameters that are responsible for arousing specific visual, tactile, and emotional qualities and explore how these surfaces can be interpreted emotively, physiologically and aesthetically by the user.
