The World's First Village of Affordable 3D-Printed Homes Is Now Complete (dwell.com) 102

MikeChino shares a report from Dwell: In Tabasco, Mexico, a family living below the poverty line recently visited their future home: a 3D-printed, 500-square foot structure with two bedrooms, one bath, a wraparound cement patio, and an awning over the front porch. It's one of two fully furnished homes -- printed in about 24 hours and finished by local nonprofit ECHALE -- that will soon make up a larger community of 50 dwellings with green spaces, parks, amenities, and basic utilities. Tabasco is a seismic zone, so the homes were engineered beyond standard safety requirements -- and they'll endure for generations. "Icon's printer, called the Vulcan II, isn't the first designed to build an entire house," notes Fast Company. "But the new Mexican neighborhood, which will have 50 of the homes, will be the first community to use this type of technology at scale."

New Story, the nonprofit leading the project, has posted a video about the homes on their YouTube channel.

  • So the house looks nice.

    However, haven't we learned in the US over the past 70 years that building massive tracts of houses from essentially the same plans/materials is, well, terrible?

    I guess it's easy enough to vary the overall design if it's being printed, but I imagine it's still going to be very clearly all the same thing, and not necessarily in a good way.

    • I don't see a problem with tract housing besides the minor nuisance of finding a house when they all look the same.
      • Wouldn't all of the houses looking the same be a benefit because it removes the ability to waste time worrying about something that isn't that important. That's why Steve Jobs famously wore the same thing every day. He found something that worked for him and then removed any chance he had to worry about it.

        If you're horribly impoverished does it really matter what the house looks like if the difference is sleeping on the street or in a makeshift shanty made with pallets and tarps?

        Why can't the 3-D printer be fed several different house plans with the same or similar cost, and make for a better looking neighborhood?
        BTW, my guess is that, once they get quality, design, and livability to a certain point, and housing authority approval, people will flock to buy 3D-printed dwellings - they'll be the best bang for the buck by far.

      'Affordable' is the key, its a lot better than a trailer park, and yes they dont look but, HOWEVER.

      1 - The inside texture of the walls is going to be a cleaning NIGHTMARE, and it would have been SO easy to plaster them flat. Completely impractical, but 'oh we wanted the photoshoot to look 3d printed!'

      2 - and while we are on looks - why oh WHY do they have to give us lots of pretty shots with the interior full of fancy designer furniture and accessories... Or do the people doing this not actually understand their target audience?

      3 - It looks like a good solid 50-60% of the walls are '3d printed', but not the window surrounds, roof interface, etc.. Flat (on or off site) precasting and on site assembly would almost certainly have been cheaper, faster, and probably given a better outcome.

      So, this smells a LOT like yet another 'look, tech is great for those unwashed poor people!' BS puff pieces, rather than an actual solution to a problem.
      I'm sure SOMEONE is making a nice pile of money out of this, but I doubt they will ever live anywhere near one of these.

        I think the target audience are either not in homes or in homes that are already very difficult to clean. They may be coming from substandard houses made with tarps, plywood, corrugated tin, etc. Part of the benefit of this method is that the extra cost of adding drywall, sheetrock, or plastering isn't needed. It may not be the home you want, but if you have the money then you can add on your plastering. This style would also work well for garages and sheds.

        I think it's the material that gives the interior walls that texture, it has to harden quickly enough that it doesn't slump.

        Have you ever been in a brick or concrete block house? Those walls look considerably worse when new. The new residents will almost certainly buy plaster and finish them, if they had built a house of bricks/blocks they would have expected to do the same thing after they moved in.

        People in most of the rest of the world don't expect to have a house handed to them on a platter, rather they expect to have to work on their own homes to improve them. You're just spoiled.

      • The slurry squirt machine has to placed around the floor plan of each house in turn, which is not scalable. The slurry has to be formulated and mixed on site close to the squirter.

        Labour is cheap where these houses are being built.

        Much simpler to mould complex interlocking blocks that construct a small house without mortar.

      • Agreed that it's a puff piece, because "3d print" is trendy. As with all such articles, the title is a lie - only part of the house was printed. Add the cost of getting the specialized gear to the location and setting it up, along with the specialized material.

        Note that the roof is flat. Disaster when it rains.

      ??? Here in Florida, virtually every home I see built is in a massive tract of houses that are all essentially the same whether the community is a low-end one or a community of million dollar homes. Almost every community even has an HOA in place to force the homeowners to keep the homes the same for all time.

      So, what makes you think we've learned this is a "terrible" idea? It seems we've learned that it is the only way to offer more for the money. The operations building communities like this are usually highly organized with multiple crews to perform each major stage of construction. Each crew can then learn to do its job in highly optimized ways. A McMansion can be taken from a pad to fully framed by a 3-man crew in three days, and roofed in another.

      This is just a method of construction. The houses produced can have far more variation in architecture than a framed house. Is every framed house the same?

      The fact that it's even possible is a great sign.

    So, if you don't have shelter, instead of cutting local flora and building one, it's somehow better to first acquire a 3D printer and the required associated artificial materials, power it up with the power source you don't have, control it with the computer you don't have, and build a structure you won't be able to maintain.

      This will be useful where you don't have access to the skilled labour needed to turn local flora into houses, or don't have access to the tools and equipment or the other materials needed. You could drop in a cargo container with printer and filament and make a bunch of houses fairly quickly.

      It could also reduce the cost of building houses dramatically by cutting out the skilled labour and many of the different materials needed.

          It's glaringly obvious you've never seen how much work and material goes into making adobe. Making adobe bricks is a specialty, most people in the Third World don't make their own they buy them pre-made or pay someone to make them on-site. This is going to be especially true in the areas where the poor live, since their plots of land are too small to make the adobes on, much less to let them sit out and dry, or even to have them stacked and curing (they can't be transported more than a few meters until they've cured at least a month).

          In short, yeah, delivering a container and teaching someone to run a high-tech 3d printer is a fuck of a lot cheaper and easier than showing them how to make adobes.

          The "high-tech 3d printer" is a concrete mixer, with a plotter-like system for printing. Concrete in, houses out. It isn't any more "high tech" than a 50 year old HP plotter. The floorplans are pre-programmed, and can be altered through "high tech" programming, but that's not required.

          You pour a foundation, then set up the printer on top, then it prints the house on the foundation. Yes, that requires more skill than a mud hut, but no more than a Quonset hut. So long as nothing breaks.

        My out of shape ass could build the walls of a house this size by myself in one day. It took me an hour to put together the walls for a 10x12 shed last weekend. Of course, it requires studs cut to length and a nail gun. I had put the floor in, including leveling the ground for the posts, the previous Sunday afternoon.

        These 'homes' have a huge amount of wasted concrete, which is very expensive for the purpose.

        • It's 500sq ft that's more like 20x25 your shed is 120sq ft and if it's a house (not a shed where the walls are just a frame and composite sheet) built on a wood frame it needs sheet rock, insulation, sheathing, moisture wrap, and siding I doubt you could build the walls of house this size by yourself in two weeks.

    • I've done considerable research into building a home vs purchasing a home vs prefab. The reason building a concrete structure is cheaper in the long run is that it requires less maintenance and is more efficient over time but the cost of time and labor makes it more expensive to build than a wood framed home. Even a wood frame home is 40% to 50% labor.

      Take out a good chunk of the time and labor involved and that would make it more affordable to build and still give you the other advantages.

If an earthquake hit So Cal, and took out 1 M homes on similar plots of land, you simply pick a street, start at one end, build a foundation, set up the house printer. Then move to the next plot, build a foundation. Repeat. After each house is printed, a team finishes the house (curtains, lights, wiring), and the advance team builds foundations.
