I get google emails whenever “3D printing” is mentioned at all prominently on the www, and the latest one definitely got my attention. It linked to a story about a guy who has been 3D printing in his garden.
A building contractor living in Minnesota has developed his own 3D printer which can print concrete directly from CAD design software, and he has used it to 3D-print a castle in his back garden.
Here is how that looks:
Calling that a “castle”, as this story does, is a bit of a stretch. At the moment, if this is anything to go by, open-air and architectural 3D printing seems to have all the deft elegance and aesthetic flexibility of a dot matrix printer. But the equivalents of laser printers, and then (what we have now) cheap laser printers, and cheap colour printers, will surely soon be with us. And in due course the building trade will become something completely different, and hence buildings will too.
Yet another reason why I would love to remain alive for another century, just to see how this kind of stuff develops.
In England, this guy would either have failed to get planning permission for this erection, or else he would now be being told to take it down, for having failed to get planning permission.
