Abstract

Purpose ‐ To illustrate the benefits of using the empirical similitude method when creating scale models with rapid prototyping processes, particularly in the context of evolutionary product design. Design/methodology/approach ‐ Apply the empirical similitude method in two experimental examples. Utilize rapid prototyping processes to create scale models. Both examples are based on the context of evolutionary product design. For one example, evaluate accuracy of empirical similitude results as compared to traditional similitude. Findings ‐ The first experimental example showed improved accuracy in the empirical similitude results as compared with traditional similitude. The second experimental example illustrated an effective approach for applying the empirical similitude method to a realistic product evolution. Research limitations/implications ‐ Limited to two experimental examples. Examples involve a single prototyping process (selective laser sintering). Does not cover limitations of the empirical similitude method. Practical implications ‐ The approach provides for an effective way of utilizing rapid prototypes to predict the functional behavior of an evolutionary product. Rapid prototypes are readily available, but are rarely used in evaluating product function, due to limitations in part sizes and material properties. Originality/value ‐ This paper provides a practical way of utilizing rapid prototypes to predict the functional behavior of a product through scale models. It also illustrates the proposed method with two experimental examples.
