Tim Shea, a 70-year-old previously homeless man, is the first person to live in a 3D-printed tiny house in the US. His story proves how the 3D-printed tiny home is more than a feat in engineering and sustainability -- it's also a life-saving technology. Shea's house is in Austin, Texas, in a development called Community First! Village, a community of affordable homes for adults coming out of chronic homelessness. Shea once faced heroin addiction, he was homeless and he most recently lived in a recreational vehicle. His new 400-square-foot home costs him $300/month, and the Community First! Village provides support programs to help residents. The very people I used to run away from, I'm running to. If you've been on both sides of the fence, you know some people just need a little encouragement and support, Shea said.
