Rapid Prototyping

New technology is really getting to the point that we can have anything we want in the time it takes to scan a drawing into a computer.
One of our group members, Nigel, has taken the opportunity of a project at his place of work to put this theory to the test.
Taking drawings published in an elderly edition of Mixed Traffic these were measured transferred to a 3D programme and transfered to a SD card. The card was inserted into a machine which heats plastic to about 200 degrees and produces a solid copy in layers of .2mm.
As can be seen, the result matches exactly to the drawing. More later!
