How long until we have the ability to print anything anywhere with 3D printing? - Justin Liguori

Justin is the Principal Materials and Manufacturing Engineer at Ursa Major Technologies and used to run materials at SpaceX

Questions we cover on the show:

1. Is it possible to 3D print engines or motors using additive manufacturing with metal? 
2. Do those engines/motors have different design constraints?
3. What time frame would it be until a consumer/tinkerer could get their hands on something affordable that could help them build motors/engines at their house?
4. What is the impact of AI on the design process for additive manufacturing?
5. Who are some other people I should interview in the space to get an idea of where this is headed?
6. Ursa major exists because of 3D printing
   1. Shortens the window
7. Will this change the automotive industry?
8. Will 3D printing ever challenge traditional manufacturing?
9. Powdered fusion
10. How many other companies have been created 
11. What is a thrust chamber?
12. What are the key components to a rocket?
13. What are the downsides to making 3D parts?
14. Are those downsides changing with material sciences?
15. What is the future of space mining and are we going to get there?
16. How much is a metal 3D printer?
17. How is all of this going to change China’s future? Is china keeping up with the US in terms of 3d printing?
