> I never heard that. It didn’t seem like 3D-printing ever showed sings of displacing existing ways of manufacturing at scale, did it? Units per hour and dollars per unit was never its strength. It was always going to be small things (and if anything big grew out of it, those would naturally transition to the more efficient manufacturing at scale).

There were articles posted on HN hyping exactly that, with comments debating whether 3D-printing would eventually replace conventional manufacturing at scale, and how people would no longer shop at stores like Walmart for their cheap products.
