Hello! I am a year 9 Australian student doing a project on how 3D printing affect our poverty issues. As part of the project I have been asked to use replies on a forum as a reference. I was wondering when we will be 3D printing all houses, or if that will even happen. From what I've read, we are quickly finding ways to make it more efficient and cheaper, so will this continue on this path or is a barrier we will most likely need to overcome first? If anyone could give me good starting ground that would be fantastic, keep in mind I am quite new to this, thank you!
