This week, we travel to the heart of the music city of the US - Nashville! We explore the big innovations in 3D design, printing, and even virtual reality at the Dassault Systemes' 3D Experience World held there. We also look at the all the action at auto expo this year - the big highlights in cars, tech in cars, and even some unique tyre tech. Panasonic adds another feather to its cap with the launch of its new IoT and AI platform MirAIe. We take a look at this and even talk to the person behind it.
