I recently had an enquiry for one of my older models and I remembered that I'd done a test print of them almost a couple years ago in FD. Infact this one I had problem with the first print, and had to get get Shapeways to do a reprint. The original thread is here. https://www.shapeways.com/forum/index.php?t=msg&goto=478 07
However, when I went to get the model, I opened the box it's in and found it had warped considerably.
Any idea what could have caused this ? The plastic now feels soft and almost rubbery to the touch. As far as I know all that has happened to this is was washed in alcohol to remove the wax and was then photographed and stashed in a plastic air-tight container to keep it clean. It's been in an unheated room in rural France so might have suffered freezing, but would not have had excessively high temperatures.
Oddly enough the original faulty model was in the same box and that has suffered the same problems, but another loco produced at the same time seems fine.
