Habitat for Humanity builds 3D-printed home in 28 hours

  The issue is always, that 3D printing saves on framing. Framing is a small part of the total. You can't print windows, doors, appliances, electrical or plumbing out of concrete.

    True and so far it builds in a somewhat crude manner that doesn't leave spaces for those other things without assistance. But hopefully over time the techniques will become more sophisticated. It also might be useful for making accessory structures and garden walls that are 90% complete since they don't need much else. I'd love to have access to one for a day to build some raised beds and most of a shed.

  I find it odd that a core part of their mission is supposedly creating long-term wealth - but then they use building tech where the long term behaviour is completely unknown. We have no experience what kind of maintenance a 3D printed house will need in 50 years. Also, a core "innovation" of them seems to be that they not just build on unpaid "volunteer" work from their own customers - but then have those customers buy back the products they just worked on. It's described in the article for housing and again in a linked article for agriculture. That seems pretty iffy.
