  1. Build­ings will never be mass pro­duced in this way. There’s no mar­ket­place, period. It’s faster, eas­ier, safer, and more accu­rate to assem­ble a build­ing from ready made pieces that come from a fac­tory (http://www.youtube.com/watch?v=E76uJi744Do). “oh, but you could print the pieces!” Great, then you’ll need a few hun­dred machines work­ing day and night to achieve vol­ume, which uses more energy and requires a sup­port staff. How does that save any money? Then there’s the way you’ll need to wash out your sup­port mate­r­ial after you print your build­ing, which means it’ll need to dry before you can go in and install fix­tures, car­pet­ing, etc.

    In sum­mary, you are kid­ding if you think there’s an indus­try here.

    • You’re an idiot. You’re like Wat­son say­ing that 6 com­put­ers is all the world will ever need.

      WHY would you print pieces? You can feed an entire 3dCAD draw­ing into the sys­tem and it will print EVERYTHING you need. You don’t think there’s a need for this? Really? So if it reduces hous­ing con­struc­tion by 50%, you don’t see the positives?

      The high­est cost in con­struc­tion in the 1st world is LABOR. Not materials.

      This machine elim­i­nates LABOR.

      Clear now?

      • Your anal­ogy is wrong. Let me restate the points you’ve neatly ignored:
        – elim­i­nat­ing labor costs jobs and only helps the 1%, so it’s polit­i­cally a bad idea.
        – a large printer requires a team of peo­ple to install and main­tain a printer while it’s work­ing. So now you have the unre­li­able humans AND an unre­li­able machine. You’ve com­pounded your prob­lems.
        – print­ing large flat sur­faces off the ground requires sup­port mate­r­ial that tra­di­tional con­struc­tion does not need. How will you remove them after the build­ing is fin­ished? Another robot that goes inside? Great! Now you’ve com­pounded it again.
        – print­ing in pieces doesn’t require sup­port mate­r­ial. Even so, it’s prob­a­bly cheaper to make tem­plate pieces on an assem­bly line and snap them together like LEGO (See pre­vi­ous video link). I hope you like neigh­bor­hoods where every build­ing looks the same. And, again, you haven’t elim­i­nated any jobs, some­one has to main­tain the assem­bly line, move the prod­uct to the site, put it together, inspect it… you’ve saved on assem­bly time, but you’re not 3D print­ing any more.

        Oh, and then we get to the phys­i­cal lim­its. Printed objects have a nasty habit of delam­i­nat­ing — com­ing apart at the seams between the printed lay­ers. I wouldn’t want to be in a 3D printed build­ing when an earth­quake hits.

        The ONLY thing a giant 3D printer will do is make it eas­ier to print build­ings with wierd shapes (http://enderender.files.wordpress.com/2010/05/800px-ariel_of_empsfm.jpg).

        Prove to me it’s less expen­sive and just as safe. Please! I love to learn.

        • Your points are valid, but only if viewed through the lens of life right now. This tech­nol­ogy would most likely be com­ing on board at the same time as nan­otech­nol­ogy, early arti­fi­cial intel­li­gence, humanoid robotic sys­tems, and new con­struc­tion com­pounds that haven’t been invented yet. That’s like say­ing “well how can we pos­si­bly build a Boe­ing 747 in 1850? The wood would just tear apart from the air pres­sure, and the steam engine wouldn’t be able to power it that far.” In all hon­estly, some­thing com­pletely unex­pected is more likely to come along than 3D print­ing build­ings, at any rate.

    • We do not yet know, what direc­tion these tech­nolo­gies will take us towards. but i am con­vinced that 3D tech­nol­ogy and addi­tive man­u­fac­tur­ing will change our ways so much that is beyond the com­pre­hen­sion of many of us.
      When the machines can print them­selves, get­ting a few hun­dred or thou­sand machines work­ing day or night is of least con­cern.
      Energy costs will also cease to be a cause of con­cern soon.
      Mak­ing things in a fac­tory and trans­port­ing them over long dis­tances will also become an idea whose time has ended, when fac­to­ries them­selves move to the point of use, in the form of 3D printers.
