The automotive industry uses various size CNC milling machines to produce first surface geometry ( outside styling geometry ). Most fabrication is done with Renboard (Ciba) or foam.

    Subject: Large prototypes
    Hi there rp-ers
    Since some months now I have read al kinds of discussions on this list. Very interesting!
    It seems to me however that most of the discussions were about systems that are designed to create relatively small but very complex shapes.

    I wonder how many of you are dealing with really LARGE prototypes, say 1 x 1 x 2 meters. Some of the discussions went about milling, which has of course the possibility of handling large volumes. We here at the Delft University of Technology for example have been working on a system using a 6-axis industrial robot as a milling machine
    (the sculpturing robot) with a planned working envelope of about 1 x 1 x 1 meters. (We didn't really produce models that big until now but we keep trying)

    I would like to ask you all if you know about systems that are fitted to create really large shapes.

    -what is the working principle
    -what kind of rough material do they use
    -where can I find more information.

    Thanks in advance.
    Very curious,
