In Part IV (Chapters 13 and 14) we discuss university and community uses of 3D printing, and how to think about careers in 3D printing in the near and long term. Chapter 13 focuses on research into both applications of 3D printing and technology development for 3D printers. Chapter 14 winds up the book with a discussion of the opportunities and challenges for teaching entrepreneurship, and tries to predict where the manufacturing and other applications of the technology are likely to be in the near and longer term.
