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
