concrete is great for compression and will build load bearing walls, giving a wider base with double rows or more . Like the hollows for air ventilation as cement absorbs water and can be effected by the freeze /thaw cycle,maybe a exterior shell troweled to give the waterproofing surface slurry a protective coating. many things one can do with cement,like counter tops with awesome colour ,patterns,art work reliefs,ect. This is exciting and has great potential for green environmental homes. Clay can be used as well A geo-thermal heat energ source with solar roof. Seeing the future from the beginning,awesome
i know this is just an experiment, but i can see how a shape like that could be used as a decorative column. In a real-world situation, as a load-bearer, it would need rebar, and some sort of filler, like polystyrene foam, so that no critters would be tempted to set up their own home in that space. Very nice.
First houses were already built with this tech. They kinda use the extruded concrete as an outlay. Rest is filled with isolation rebar and plumbing/wires and filling material. It works perfectly though the tech is not as advanced as it should be for building bigger things like 3 floors and higher. But I think we are going to build concrete houses only with this method in the future.
American homes also have open spaces in their walls (the not insulated ones then). Those people also live there ok with or without critters. But it's better to insulate the walls of course.
It means u r said that the open spaces which is left in 3d printed wall is responsible for reinforcement and electrical, plumbing works all these things.is it right🤔
It means you said that the open spaces which is left in 3d printed wall is responsible for reinforcement, electricity, plumbing works are done with that open spaces?is it right
This head is ok but i have advice . Under the nozzle i would set material boundaries on both sides with small metal plates. These two plates must be raised by a relay when the robot deviates from a straight path. I have idea to upgrade this nozzle and results be a flat structures from both sides. Now the Layers have a uneven surface , not flat
It' amazing, but I see a few other HUGE opportunities since the installation and footprint of the printer is a major factor and effort. What if the printer head could be swapped out to do more than print? Ambitious robotic goal, but what if it could also dig, level, move, sort and mix? Also, whatever this cement mix is it's likely 90% sand so what if that sand could be extracted from the job site significantly reducing the largest material needed?
Funny how they used an actual overhead crane for this. You need some courage to buy an overhead crane for this purpose (many 10.000's of EUR) to rip open the electronics box and put your own controller on it.
That's the trouble with all this stuff. PILES of money PLUS cant be done in wind so needs to be done IN A TENT PLUS electricity AND FAR LESS strength than normal concrete and frankly you would have modular formwork set up and concrete poured in the time it took TO SET UP THE TENT let alone the crane and electronics and generator. It's like using a robot to butter your toast and pour your coffee. Just easier to do it yourself the simple way.
it might seems like the future. nut it's not. it is no more then a process that is new and as many people are like little children getting excited about the yiniest little thing. putting up rebar and temporary inner an outer wall is still way chicker and more reliable. i think dome houses are a hood way to go especially for hurricane troubled area's on this planet. 3d technology is good for small things that have a small impact on your life.
+Elizabeth Green They use a rectangular nozzle to control the width of the extrusion. They are building a shape with more than 2 dimensions [degrees of freedom] (forward/backward, up/down), ergo, they are not building a straight wall - it curves around the corners of the structure - so the rectangular nozzle needs to be articulated to control for a 3rd dimension (left/right). If the extrusion is wider, then the load face has more surface area, thus producing a member where the load is more evenly distributed and more dispersed. Load-bearing capacity is directly correlated with load distribution. Also, building codes require some minimum compliance in load-bearing structures, especially if they are going to be inhabited. Thus it follows that an articulated rectangular nozzle is used as opposed to a circular or square extrusion, in order to increase structural integrity. Structural integrity requirements are set by regulatory bodies like the ICC/ANSI, or by local, state, and government bodies.
Both extrusion width and it might be because of layer translation since it almost cork screws the layers upwards since the machine can't stop extruding at any time.

No . they collapse in on themselves when the angle gets too steep. Realize that all this stuff is STILL WET as the printer is still running. AND you need to do it in a tent because the wind can cause collapse. The best bet for domes is those angled bricks. Or an upside down mold and then turn them upright with a crane.
@@OffGridInvestor Actually it is possible, but you need to control precisely the yield stress/structuration rate. Also, there is a geometrical problem of local geometrical control of the layer, which governs the rheological strategy to employ. We did a small dome (50cm diameter) with a bicomponent strategy, it would be easier to print larger structures because the material is accerelated at the end of the process.

th-cam.com/video/XgPJdpGV8mE/w-d-xo.htmlm52s look in the background look at those concrete. Look at the sharp edges and square structure

Would you be able to share the design for your nozzle? It is by far the most useful i have seen

Interesting but until you can also implant rebar it's a no go.
What material are you printing? - Yellow concrete?
How many layers can you do before weight causes failure of wet concrete?
I think the cement is quick enough to dry before too many layers are added on top.
I remember seeing a story on this - the biggest challenge was finding a suitable concrete that could hold its shape quick enough to hold.
Has anyone found a mixture that will hold fast enough to be printed on top of?
@@laurenhunter304 You mean like the guys in this video?
is there really good adhesion between the layers ? i would think it should become one does it ? i would love a house built by that baby !!!!!
thanks buddy i thought it should what n idea !!!

Would you please explain how the superstructure joint with foundation? Pls reply as soon as possible

thats what everyone thinks until they start doing their homework. MudBots.com
Why do you use the articulated square nozzle instead of a round one?

can you print domes?
