Discussion Questions:
  1. What is “additive manufacturing,” and how does it differ from traditional manufacturing?
  2. Describe two methods two of 3-D printing.
  3. What is an example of engineering optimization shown in the video?
  4. Critical Thinking: Review the NASA link, and consider the following question: NASA’s International Space Station manufactured and produced the first 3-D object in space in 2014. Theorize three ways in which this advance can impact future space exploration. Are there challenges as well as advantages associated with 3-D printing in space?
