Hi @stan ! 3D Printing is amazing. I tested it from its beginnings when it was just for small 50 cm prototypes. Looking at it as a disruption to the construction industry is crazy, but considering all the research being made, and the current technologies, including an australian company that is already building homes with this technology (https://www.fbr.com.au/), I made a few posts about it, I believe this is the future for construction, and

why not bitshares 2.0 being the means of payment and other logistics been constrolled with EOS smart contracts?
