Description
The design freedom of Additive Manufacturing (AM) is both an advantage and a challenge. More than ever, we need assistance from the computer in exploiting the manufacturing capabilities. Even though Computer-Aided Design (CAD) has been around for 40 years, it is still not ready to fully support design for AM. Meanwhile, the fields of structural optimisation and generative design have developed tremendously and are now at a stage where they can semi-automatically explore the full design space together with the design engineer. The presentation will touch upon several topics:
First, a high resolution topology optimisation method capable of designing parts at the manufacturing resolution will be presented. This significantly lowers the component design time and is an opportunity for structural integration between RF components and the full assembly.
Secondly, I'll show how this traditionally mechanical optimisation paradigm can be extended to thermal problems on both the micro and macro scale, for instance minimising mechanical deformation while securing parts with isothermal surfaces.
Finally, I'll touch upon the generation and manufacturing of huge complex lattice structures with millions of rods, which are used for controlling thermal properties of AM parts.
JUSTIFICATION FOR THE CONSIDERATION
Though not directly aimed at RF applications, the presented work is highly relevant for AM design in general and complex designs where conflicting mechanical, thermal and dynamic properties needs to be balanced in a complex multifunctional design. Building on the authors extensive backgrounds in both metallic AM and structural optimisation, we present the state-of-the-art within this combined field.
