Whereas, in general, the additive construction hype is focused on houses, I’m much more focused on 3D printing money. I think that locally 3D printing mass-customized infrastructure at a factory and then trucking the parts to building locations is the most logical, profitable, and impactful opportunity out there. For the developing world, it would mean that the single most important infrastructure elements that can be 3D printed would be made to spec regionally, as per the most pressing needs. So, stakeholders wouldn’t put in a whole sewage system centrally, but print out septic tanks and cisterns where the need is the highest, resulting in the highest impact. Such an approach also lends itself well to disaster relief. The U.S. military is already looking at this, just starting a $3.5…
