In this bonus, hour-long episode, Cara chats to Dr Kate Black about her research focused on Additive Manufacturing (also known as 3D Printing) where she works on developing new techniques that will allow us to 3D print a wider range of materials, like metals and ceramics.  We also cover her background in Chemistry, her resilience in overcoming adversity during her incredibly inspiring academic journey and whether there will ever be 3D printers in every home.
