Here is link to 3D house printing video. There is one more video that shows stairs being printed. What do you think?

Looks like it will make nice planters boxes. I’m not certain that I would trust it enough for my family. Bonding layer to layer and infill to perimeter seems critical. Even if the concrete is fiber reinforced, the lack of visible steel reinforcement is an issue for me personally.
@Alan_Thomason The design for the stairs looks sturdier. I do agree with needing some rebar. I think most building codes in the U.S. would require it. If I could afford the printer I would get it and design something where I added rebar. So far, the only 3D printed structure in the U.S. is Andrey Rudenko’s castle.
There is a lack of reinforcing in these constructions, it’s a good Beta but not ready for production. It really needs to print onto a mesh or preassembled reinforcing.
But still interesting to see, thanks @Sandra_James
It looks so dimensionally inaccurate that is almost impossible to apply thin plaster (or insulation system for not so warm countries like the most of Europe).
It will be super obvious that 3D house printing, when perfected, will be inferior to about every other method of construction.
Why cant people get trough their thick skulls that 3d printing is not a universal solution to every problem they are to lazy to grasp the traditional mastery of.
3D printed buildings on the moon would work.
I agree. Additive manufacturing (3D printing) perfectly complements traditional manufacturing methods. It is not there to replace most of them. On the other side (as a former active civil engineer) I see its chance in the building industry.
I would like to see bridging and free formed shapes. What’s the point of 3d print rectangular shapes?
3d printing can do the foundation, floor, and walls - maybe 70% of a house. If they can figure out the reinforcement, concrete houses could be very safe from fire, wind, water, and possibly earthquakes.
Maybe that printing would if there was fiber added for strength as well as printing vertically. The process shown is all horizontal layers which give strength in one direction. Vertical printing onto the horizontal form might add the extra strength. Or, the gap could be filled to add strength. Still not as cost effective as blocks or those large poured slabs that are lifted to form walls.
@Brett_Cooper Did you get a chance to see the stairs video? There was more enclosed framing (that may be the wrong way to describe it) in the desgin. Do you think this makes a more sturdy object?
I Sure Hope they don’t use PLA
