Cathy Lewis, former CEO of Desktop Factory and now VP of Global Marketing for 3D Systems, recently made an appearance on Discovery Channel Canada's Daily Planet science news show.
In the short interview, Cathy explains the basics of 3D printing and displays a variety of different printed objects, including one with moving parts. She spoke of different applications, including personally-shaped bandages, replacement bones, parts for repairs, etc.
Daily Planet host Jay Ingram didn't seem very familiar with the concept of 3D printing and was quite amazed to witness its capabilities. He was especially thrilled to learn he could (theoretically) print out replacement "houses" for his home Monopoly game.
That's definitely possible, but perhaps it might be cheaper to buy a new Monopoly game.
