Abstract:

Bio-inspired design is an innovative methodology for transferring biological solutions into technical solutions, for example for the design of weight- and load-optimized components. Bio-inspired design therefore offers great potential for meeting the challenges of designing additively manufactured components, such as avoiding warpage, supporting structures and material minimisation. Nevertheless, apart from bio-inspired topology optimization tools, bio-inspired design is rarely used in industrial practice because for many companies the practical applicability up to the prototype is not obvious. The aim of this work is therefore a practical approach to the search for biological systems, analysis, abstraction and transfer of analogies. We apply bio-inspired design on the design of a microtiter plate manufactured by stereolithography, whose dimensional accuracy is impaired by warpage. Here, the venus? flower basket, a deep-sea sponge, can serve as a model. It has a hierarchical structure of silicate needles whose elements are abstracted for bio-inspired transfer. We show and evaluate the transfer of different analogies using a prototype.
