This week we present three conversations from IMTS, the giant manufacturing technology trade show that comes to Chicago every other year. In this episode we speak with Spencer Wright, author of The Prepared and head of partnerships at nTopology. He's an authority on 3D printing, so he's able to make sense of the enormous range of 3D printing processes and machines that appeared at IMTS this year.

Be sure to listen to the other two episodes in this series, #13 featuring Inventables CEO Zach Kaplan, and #14 with Elizabeth Koprucki from the University of Chicago's fab lab.
