Abstract
Feature databases for additively manufactured (AM) designs have been identified as a promising tool to support engineers during the design process. This paper investigates the implementation of such a system by conducting an industrial case study. It provides empirical insights for implementing AM feature databases in industrial practice and a quantitative assessment of its impact on the design process. First, the process of formalizing a firm’s current AM design knowledge is described. By screening existing AM designs, recurring design elements are identified and structured within a feature taxonomy. The technical implementation of the tool is presented with a focus on the database structure and feature parametrization. The twofold repository consists of a web-based cataloguing system for feature look-up and a CAD integration for feature import and modification. The application of the tool in a real development project demonstrated that the feature database supports designers throughout the development process by providing prior validated and scalable design elements. Both development time and cost were reduced by decreasing the number of iterations necessary to achieve a robust design in the detailed design phase. The database also facilitated the conceptual design phase by widening the individual design space of the designer through inspirational input.
