> It didn’t seem like 3D-printing ever showed sings of displacing existing ways of manufacturing at scale, did it?

There was a point of time where some people looked at 3d printers and said "Wow, imagine how great this technology will be in 20 years." There was some amount of anticipation for multi-material printers to come around and for home printers to begin replacing traditional consumer goods. Compared to crypto, vr, and ai it doesn't look like much but 3d printing did go through a hype bubble.
