EU's first 3D-printed house is the most livable we've seen to date

I think that looks really nice. I would not mind living in that.

Looks fine, but getting planning permission for that through the average suburban planning department in the UK, is as likely as pigs growing wings. That corrugated surface, is guaranteed to collect dirt, and look absolutely terrible in a very short time, so plastering inside and out, plus a washable paint surface, would be essential. Anything that can provide homes, rapidly and cheaply, must be good.

Now we're getting somewhere! This house is attractive, inside and out. On the inside the walls have a pleasing texture. It's almost as if they are fitted with an expensive "corduroy" wall covering. Actually, it looks quite elegant. I agree with Tom Lee Mullins, where do I sign?

That is nice, I wonder if they can print straight walls.

Cute, a million yrs ago round homes were tried, they were called domes, and exhibited the same issues, problematic wall surfaces, custom furnishings, problematic adaptions for fittings like doors and window, running utilities. Domes did inherently solve one problem the 3D printing fad doesn't, Domes are structurally self supporting, very much so. Here's a short list of issues printed building need to address before they move beyond amusing trade fair demos Structure - presumably via integrated reinforcing, presumably a polymer that will replace rebar and be spray one drop at a time like a different colored ink to form the needed structural grid in walls. INSULATION - how is it that is not being sprayed along with the walls and finishes with cement plaster? Not that I'm a believe if petro chemical foam insul, it's indefensible environmentally, embedded energy and CO2 is enormous. Utility chases / conduits / ducts etc, which again should be formable by using polymer spray for the wall and nothing in the void area, unless you want to try spraying in pull lines for wires / tubing. Integrated and fully secured sub framing at openings for windows, doors, etc. Again a sprayable polymer that would create a "plastic" lumber sub frame would work. Smooth finishes Final finish So.... why is no one doing 3d printing bothering to implement even the most basic of these necessary features - concentrating instead on pouring cement. Finally of course the 800 lb gorilla, floors and roofs, small object 3d printing can accommodate fully 3 D shapes with hollow insides, which is what a house is, yet, again, not even being attempted. It would just take side spraying structural elements across spaces one drop at time, along with "dissolvable" temp bracing periodically. Ideally, you'd probably aim for a self supporting skin like a dome, but much flatter, between ribs, which was in days gone past called a Gustav?(Guastavino) tile arch used for ceilings / floors.
