3D Printers To Build Houses

gbjbaanb writes to point out an article in the Sunday Times describing two separate programs where robots are being developed to build houses. The Los Angeles project is farther along than the one in the UK, but the article provides more details on the techniques employed in the latter. Liquid concrete and gypsum will be sprayed from nozzles in a manner analogous to an inkjet printer. From the article: "The first prototype — a watertight shell of a two-story house built in 24 hours without a single builder on site — will be erected in California before April. The robots are rigged to a metal frame, enabling them to shuttle in three dimensions and assemble the structure of the house layer by layer. The sole foreman on site operates a computer programmed with the designer's plans... Inspired by the inkjet printer, the technology goes far beyond the techniques already used for prefabricated homes. 'This will remove all the limitations of traditional building,' said [an architect involved with the UK project]. 'Anything you can dream you can build.'"

      True. The building trades are moving towards technologies that can be automated. For instance, plumbing is using a plastic semi-rigid tubing called PEX. It's sold in sticks, but is flexible enough to be delivered on large reels. It's crimped onto brass connectors - nothing that couldn't be done by a robot. A regular plumber would do the finish work of connecting the toilets, sinks, baths, water heaters, etc.

      Same thing for electrical work. Most houses are wired with Romex, and 3M introduced a crimp Romex joint that could easily be applied by a robot. The robot could ink-jet print all the information about where the wire stubs coming out of the walls come from or go to. The electrician would then just finish the house by connecting the breaker panel, switches, outlets and lights.

Reinforced concrete is of course much better because the steel prevents unhindered expansion. Best of all is prestressed concrete which has cables or rods under tension embedded in it placing all of the surfaces in compression up to some limit. A couple years ago I noticed prestressed concrete foundations used in new California single family housing making me wonder how many foundations had actually failed.

      Tempered glass is similar in that it is manufactured in such a way that the inside is in tension but protected from fracture by the surface which is held in compression. Once a crack reaches the inside, the glass tends to release all the stored strain energy yielding the spectacular failure some may be familiar with. Trees work in the opposite way since the strength of wood is reversed from stone or glass. The inside is in compression and stretches the skin into tension. This is especially important since the failure mode in bending of a tree is usually buckling at the surface which happens at a lower strain then the compression strength of wood would indicate.

      After watching the video of a 3D printer posted a few days back, I don't really understand how they do the top of things. What do they do when the top is flat. The way some 3D printers for rapid prototyping work is that they mix a type of glue with the material the object is made of -- let's say it's sand. So when you're building something, the printer is effectively outputting a cube of sand layer by layer but for each layer, where the object's structure is there's the cross-section of glue also laid down. I'm probably not explaining it that well, but I hope it makes sense. A flat surface will be supported by all of the sand that's beneath it. When the last layer is done, you let it set for a while so that the glue hardens and then you take some compressed air and blow away all the sand, leaving the structure of the object behind.

      The article was vague so I'm not sure what method is used, but I doubt you'll be blowing away 500 cubic meters of concrete and gypsum powder to reveal your house structure at the end. So I'm also wondering about any flat surfaces.

In my hometown of Duluth (about 100,000 people), we could rent a 5 br, in a similar neighborhood for around 200-250 per person. A single br w/ kitchen is about $450.

The average wage difference seems to be about $2 for jobs in the $5.15 - $15.00 per hr range.

Why pay more for materials and labor when it only has to meet code and stay standing long enough to sell it off? Even 50 years ago, people built houses assuming they would live there forever and used materials that would last. Today I see new home with shingles rated to last 10 years. 10 years ago, no one made shingles with that poor of durability because there was no market. Everyone wanted 20 or 30 year shingles at the least because they planned to be there in 20-30 years, at least.

      New builds this century are already starting to look a bit decrepit as the wind and rain (which are thrown off by our local stone) do their work on cheap modern building materials.

      Most people who build homes today build them of lower quality materials and workmanship. This has nothing, however, to do with concrete being a poor choice, especially if you are planning on building a home to last. When I build a new home, I will almost certainly use concrete because it will last longer than most other construction methods in use today. The point is to do it properly, which is a bit more expensive.

      Concrete with re-bar is reinforced concrete. Re-bar is not only put in to resist tensile forces due to bending. Re-bar is put in to prevent the concrete cracking. That said there are systems (developed for spayed concrete in tunnels) that incorporate steel of syntheic fibres which have a similar effect to re-bar but are just mixed into the concrete.

      Given other comments in this discussion is is probably worth noting that brick walls have no tensile strength, unreinforced concrete is better. As long as this approach is only used for vertical walls there is no need to reinforce (except to rpevent cracking as mentioned above).

    - Noise - No cracks in walls so the house should be quite isolated from external noise.
    - Easy to add thermal and noise isolation in the building, just add a foam-spray nossle to the robot and you can have automatic isolation in the build-process. add a layer in every roof/wall and it should be very noise-resistant & have good thermal isolation.
    - Fire persistent - If you build every wall in the building in this material fires should not spread easily between rooms the building.

    Cons:
    - Since it's a very static building it will probably not be very resistant even to small changes in ground-movement, but maybe they can fix this with adding some type of rubber-seal between walls in the build-process.

If the GPS receiver cannot receive a signal, or the licensing server does not report that the building is approved at the current location, or the component validator detects unauthorised modifications, then the software will signal all the construction materials to shut down, causing the house to collapse and protecting you from the dangers of building piracy.

  95. Of course, how else does R&D get paid for by AHumbleOpinion · · Score: 1

    The cost to build will be slashed enormously, given the elimination of hourly immigrant labor, but somehow, somehow the price to the buyer will be the same as stick-built, or slightly lower. The savings will be passed on to the builder -- always.

    You are ignoring the enormous R&D expenses that have to be paid for *before* that first home is built. The developers are going to pay quite a bit for those first robots. It's not necessarily that the robot inventor/manufacturer is trying to rip off developers. The inventor/manufacturer may only have 3-5 years before competitors have their own robots, they may need to recoup that R&D quickly.

  97. 3D printing - from micro to macro by FrenchSilk · · Score: 1

    Today I read two articles about 3D printing, TFA and one about printing micro miniature machine parts.

    While the technologies are different, they both convert a digital representation of a 3D object into a physical object by spraying construction material out of a nozzle. From tiny ear bones to four bedroom ramblers.

    What an age we live in!

  100. I wish a robot had build my house ... by JunkMan1989 · · Score: 1

    The walls might be square, the windows might all be the same size (so I coud buy blinds that fit), I wouldn't have wall outlets on the same circuit with the lights, the basement plumbing for a toilet would be useable because it wouldn't be too close to the wall, I wouldn't have two different circuits feeding one wall outlet, and I could put furniture in the little bedroom (can't get anything larger than a twin bed through the door in the hall).
