    This is really impressive, cement printing is a very difficult thing to actually do, Great Job.

      Have you tried, Rich?

      • RichRap

        Yes, for some time, getting better results. It’s why I designed my 3DRmega printer that can have an open base so you can print cement sculptures directly onto concrete paving slabs then lift off the printer. I’ll post more about using pumped paste materials soon.

          Wowzers, Rich! That’s awesome! And the print to the right of the machine looks super realistic!

    I’m very impressed with this. It’s really amazing how neat and clean this printing is working with conventional cement material. I would have expected that to be much more difficult. And for a home-made prototype, this is printing remarkably uniformly. This is a great project and Rudenko demonstrates superior skills with this. I’m curious as to what the machine in the custom roadcase beside the laptop is. Could that be the printer controller?

    It’s interesting to see how this house printing concept is catalyzing so much interest–and how it all seems to be emerging from different parts of the world at almost the same time. It looks like large format 3D printers and architectural printing are going to be in the news a lot this year.

    This new technology and development, and all new ideas people have is great. But, when I read these articles I think that all the hype around 3D printing is a bit of overkill (do not doubt; I’m all fully involved in 3D printing as an entrepreneur in business!).

    My point is that today any welding robot, automatic pouring machine or other device which extrudes any material from the nozzle or tube, and moves the nozzle itself using any kind of a computerized system, is called a 3D printer. These machines in many variations have been there more or less decades, why they were not called as 3D printer some 30 years ago, in other contexts, on steel works, factories or construction sites?

    So, man in this article; is he really 3D printing house, or is he “just” casting it of suitable mix of concrete, using an automated casting machine? I can’t say where to set “limits”, is it 3D printing if molds not used. In welding they never used…
    Sure it’s most fashionable to print house these days.

      The hype is pretty big (though I think it’s starting to deflate a little bit). When reporting on these stories, we usually try to point out when something is too hyped, while informing those interested in the technology. That is, unless we’ve been taken in by the hype too! We also try to regularly describe the blurry boundaries of 3D printing. Here’s one instance where I talk a little about it: http://3dprintingindustry.com/2013/08/26/is-it-3d-printing-mit-researchers-construct-building-blocks/

      My personal opinion about reporting on topics that may only loosely be considered 3D printing is that we should acknowledge them as loose 3D printing or not 3D printing, but that we should still report on them, as it may inform others in the industry about the possibilities of their own craft.

      Raemoe, I think you’re off base here and letting your Buzz filter overwhelm the facts. He is extruding a house. That’s groundbreaking stuff. Extruding is many times faster than any other concrete construction method. The ability to extrude based on CAD data is a huge plus and will enable advances in architecture and HVAC efficiency.

    Is there a company that we can buy them from?

  • Electra

    how much would a 3D printer of that size be as I am starting to think I will never be able to afford a house of my own with cost of living prices going up
