| Sure, you have 6inches of concrete, but that just makes it more
| expensive to build.
|
| From what I can see, its probably cheaper and quicker to pour
| ICF(https://en.wikipedia.org/wiki/Insulating_concrete_form). They
| are basically uber insulative, super quick to build, and support
| multiple floors in one pour.
|
| The only way I can see the "3d" printed approach being either
| Eco(cheap) or Eco (earth friendly) is using doing a rammed
| earth/adobe system. At least then you only really need to dig up
| earth, power the machine, and boom, you have walls.

| Good luck putting furniture against those curved walls.
|
| I don't see how this is any better than prefab concrete panels.

| Interesting. I wonder how long they last. Could be good solution
| to address supply issues.

| Sounds like vaporware in the short-term. Are there any shipped

| It's probably more accurate to describe this as a new way of

| materials in the house are the traditional kind and will be
| installed in the traditional way.

| What is total cost on these?
| alexvomwald wrote:
| They didn't disclose but I am guessing average compared to
| market. They're not cheap but they seem to be good quality. ps
| - median price of a home in Austin is $624,000

| There has been a lot of discussion about 3D-printed homes over

| One of the biggest home builders in the US announced a 100 home
| community in Austin and homes are expected to be available for
| sale soon.
|
| What are your guys thoughts? Do you think a 3D-printed home would
| be a good investment?

| You could take all the city zoning/codes/ordinances away
