Nowadays new manufacturing technologies like the additive manufacturing in conjunction with the associated resources utilization requires a rethinking about sustainability. To continue the idea of an efficient technology the evaluation of sustainability is analyzed in this article. The examination starts with a general description of sustainability by the combination of different definitions. Based on this knowledge, the challenge to evaluate different process chains in various manufacturing technologies is investigated. As a result an approach for the evaluation of the sustainability in relative comparison of different process chains is developed. In the study the additive manufacturing process chain is faced with the shape cutting process chain regarding an aluminum component. After the introduction of the approach to evaluate the sustainability of both technologies the methodology is applied at a demonstrator. Thereby a geometrically complex component is used, which is shown based on a reflector from the automotive industry. The calculated results allow an assessment of the sustainability of individual process chains in a relative comparison to each other.

Keywords: Sustainability, Design Methodology, Additive Manufacturing
