It’s a gimmick. There is no point other than marketing.
Early attempts always look gimmicki.
Putting a camera in a phone, crazy, who needs it, just a gimmick. I use my phone to dial numbers and make calls.
This looks like it has a lot of room to grow and adapt. Materials change.
Just look at how 3d printers have changed in 10 years.
They have evolved into true click and forget machines.
I don't have a 3d printer myself so maybe it'd be obvious if I printed some.
I say most because there are finishing methods which can largely obscure these details and make it less obvious as to which method produced a given part.
When I look at 3d printing advancements, I have hard time not thinking that with scaled up to houses, they wont have similar advancements, with time and resources.
Kind of like Steam Engines. After the Steam Engine was invented, it took many decades to dial it in to the large 'more' efficient models we are familiar with. It seems like large 3d printing will take a similar time period to grow to industrial levels.
Even the Iphone, wasn't that great at the beginning.
Maybe my overall point. They have made an entire neighborhood with a 3d printer. That seems to be now over the hump of proof of concept, and now there can be steady improvements.
