    I read a short article about this "3D Printing". Laser processing, electron beam melting, very exciting industrial processes. I still can't get my head aroud it. Print yourself a new pair of shoes in the morning and a ferrari overnight, so says the article. Is this the future for housebuilding? Forget all that concrete and bricks just pour the raw ingredients in a hopper and away you go, and all from your PC. It could sound like manna from heaven for Tom Foster's vision of the brave new world.:smile:

    A few years ago I read that NASA where working on a machine that can build a house from poured concrete.
    Having used a 3D printer (and the associated scanner) all I can say is that they still have a long way to go, not that that is a reason to not like the technology. I do like the idea of getting rid of people on building sites. but then I am a fan of factory built housing.

    The source to the 'inhabit' was the article I read. Think they said it could do windows, plumbing and wiring, but shall wait until I actually see one.
    We can all claim a lot of things we have thought of. Doing it is the hard bit :wink:

    The concrete stuff is great, but there are companies already producing complex metal and ceramic components, without moulds etc. Additive as opposed to subtractive, "conventional " engineering, with probably much less energy requirement, but like you say a long way to go.

    Sintered con-rods have been around a while and I know they are experimenting with similar metals but using lasers to 'cast' the material.

    Cob houses are built pretty much by an 'additive manufacturing' process. :bigsmile:

    Current 3D printers all need to be bigger than the object they are printing, AFAIK. So we need a different idiom.

    It can be done. Saw a documentary once where they reproduced Sigorney Weaver from...

    What?!

    Somehow that conjures up an image of a big robotic manufacturing arm, fitted with a giant welly, stomping mud, cow shit and straw down to compact it......................

    Yeah, and despite the ingredients, she looked bloody amazing.

    Stick to Winnie The Poo.

    Wonder if they'll ever do a remake of that featuring Bruce Willis? Probably called 'Fatal Winnie and The Dark Forest'.

    But being serious for a minute, there is a 'demonstration' of AM on YouTube somewhere showing an adjustable spanner being made. Had to laugh because it brought back memories of left-handed hammers and long-weights.
