Abstract
Identified in the European strategy as a key enabling technology, Additive Manufacturing (AM) has a great potential for industries to reshape, improve and optimize product life cycle, with reduced environmental footprint such as material waste in production. Allowing to meet structural and multi-disciplinary requirements with complex freeform design at a much lower weight than high constrained conventional manufacturing, AM can benefit to numerous space applications. Beside manufacturing process development, software and process control are becoming absolutely necessary to support digitalization of industrial workflow. Dedicated tools such as Computer Aided Design (CAD), Computer Aided Engineering (CAE) and Computer Aided Manufacturing (CAM) were introduced in the digital manufacturing chain; however, their development was driven by standard manufacturing processes. Therefore, appropriate design methods for AM must emerge in a fully integrated end-to-end solution to foster and support the growth and competitiveness of AM. In order to support industrialization of AM, the European Space Agency has selected the Design4AM project, based on a strong partnership between Siemens and Sonaca, for “Development of Design Methods for AM including CAD Design, Optimization, FEM Analysis and Manufacturing features”. On one hand, the project aims at combining within a comprehensive end-to-end process, topology optimization, seamless CAD data flows and predictive process simulation in the Siemens’ NX™ and Simcenter™ environments. On the other hand, the integration of dedicated industrial design workflow within the enhanced Siemens Digital Innovation Platform is validated on a relevant ESA space application provided by Sonaca.

Summary
Legacy software and process control involved in Product Lifecycle Management (PLM) and initiated, for instance, as dissociated CAD/CAE/CAM tools in response to digitalization needs for conventional manufacturing, are facing new challenges this last decade. Soon as possible in the design process: performance requirements: with optimized parts subject to their full environment(s), in which several configurations may be involved in service; manufacturing requirements: with, for instance, self-supporting structure with respect to build orientation directly generated by topology optimization, and predictive AM process simulation allowing compensation of thermal distortions. In this context, the European Space Agency (ESA) selected Siemens and Sonaca for development of design for additive manufacturing applications. This will provide a robust design, sizing and AM process preparation methodology supported by a single software environment
