Parametric Modeling of Bio-inspired Luminaires for Additive Manufacturing Technologies

The development of 3D modeling tools has allowed the construction of geometries that were unattainable computationally until a few decades ago. Specifically, parametric design and modeling is gaining significant importance in the conceptualization of new designs and products. This communication shows some of the resulting prototypes, designed and manufactured by INNANOMAT research group (TEP 946) of Cadiz University. A product design methodology for Additive Manufacturing (AM) and functional luminaire models proposed in the scope of two projects: ADICORK and 3DBLEND. In these projects, bio-inspired texture designs were explored in natural elements and environments of the province of Cádiz, in order to highlight this region and the value of its ecosystem. In both projects, sustainable polymeric blends were developed that served as base material for the manufacture of part of the prototypes shown in this communication. For these designs, parametric design programs such as Grasshopper, a Rhinoceros plugin, were used to obtain complex models that achieve a unique and differentiating aesthetic. The result of the modeled texturing is combined with surfaces in Rhinoceros. Once the textured model is defined, it is detailed and finished in modeling programs where dimensional control is greater, and the design is adjusted to the specific AM technology chosen. In this case two were used, Fused Filament Fabrication (FFF) and Fused Granular Fabrication (FGF).
