All fantastic points and so far the market agrees with us

I don't know much about 3D construction techniques - but I do have 3D printers.

I imagine the problems with construction pretty much mirrors the problems with 3D printing anything:

I'd imagine for simple smaller buildings (rectangle shape with a few door / window cutouts) 3D printing could probably work great.

However, if you have large buildings or complex shapes / architecture then it might not be worth it. Further, being new, what is known about long term durability.

3D building printing dead? ICON is struggling. Raised more capital in a series C

I don't know much about 3D construction techniques - but I do have 3D printers. 

I imagine the problems with construction pretty much mirrors the problems with 3D printing anything:

* Material durability / layer adhesion 
* Size of thing being printed
* Some shapes are just hard to print
