88458 - Additive Manufacturing Strategy for Ultra-Lightweight High Value-Added Components 

Additive manufacturing and its growth in advanced industrial fields is changing many process paradigms for the development of highly customizable components. It condenses the traditional approaches to produce assemblies that are more and more integrated at different levels: functionality (strength, lightness), productivity (flexibility, customization) and development (passage from the digital part to the final part). Many studies continue to address the changes that this implies in the context of Design for Manufacturing. There is a need to join creative innovation methods like Design Thinking to concrete technical realities: numerical criteria, machine specifications, etc. 

This work presents a methodology to help select a combination of possibilities (materials, process, etc.). Derived from the double diamond method, this methodology aims to propose a rationalization of the choices available to designers of high value-added products with strict and mutually intertwined requirements. A unified evaluation metric creates a combination of disparate factors that can then be compared to other arrangements. The whole methodology is then illustrated with the design of an indoor aerostat drone which illustrates the implementation of some of the key elements of the proposed process. By being able to visually represent compromises resulting from many different requirements, the objective is to demonstrate that the method is applicable across many domains.
