Hi All, I need a flexible sheet in my model and I found this video http://www.youtube.com/watch?v=wXgbJB9v6Zk&feature=playe r_embedded#! What is the thickeness of this piece to make it this flexible? Serge
For a wire, 0.8mm is very flexible - see; http://www.youtube.com/watch?v=XNXz1D0R0Ls - with a sheet the same thickness will be stiffer, but you are able to go down to the minimum wall thickness of 0.7mm for WSF if the area is not too large.
The short answer is simply: you just can't do that under the current design rules. To achieve that sort of flexibility you'd need a wall thickness in the range of 0.3-0.4mm, but Shapeways no longer permits models so thin because of production issues. (The rules have changed since that video was made.)
