Additive manufacturing (AM), commonly referred to as 3D printing, is a booming technology (or, better, a set of technologies) in a number of application areas, including architecture, automotive, aerospace, biotech, electronics, fashion and food to name just a few. AM actually encompasses a broad array of processes aimed to directly synthesize a 3D object from raw materials, using a layer-by-layer deposition or growth sequence under computer control. In the electronic market, and specifically in the RF and Microwave field, from expensive satellite communication systems to high volume microwave electronics, AM has the potential to change the way systems are designed, integrated and operated and is therefore considered a strategic technology and a key enabler for accelerated engineering processes, highly efficient products and new agile supply chains. Totally new design approaches that will improve performance, make mass optimization practical, allow the miniaturization of complex systems and dramatically reduce the design/manufacturing/assembly cycle costs are possible with AM. Along with these attributes AM provides an environmentally-friendly alternative to conventional manufacturing. This webinar will present a review of the current state of practice in additive manufacturing for RF/microwave applications including those areas where much remains to be done.
