This has to be the most common gripe that I have written about using Shapeways service, along with many other people complaining about the same thing. I thought that Shapeways had come to a solution to this already? I have had one of my designs printed in WSF. The piece includes a hinged part. I received no notice from Shapeways that there might be a problem and when I received it the piece had printed exactly as I wanted. I then included photo's of the model on the model page and opened it up for purchase. Now, because someone wants one in BLACK SF I get notified that the order is cancelled because the tolerance on the hinge isn't sufficient! This is my number one complaint with Shapeways - as it is with many other members. We go to the time and expense of getting models printed for ourselves to prove it will print, and then you go and reject it when a customer orders! I can understand if it was a different material, but, no, this is the SAME MATERIAL, just a different colour. This rejection process makes members look like buffoons with no sense of credibility to the buyers. What happened to the implementation that I thought Shapeways was going to do, or had done, whereby the Maker gets notified of a problem and is given a chance to work it out with them before the order is cancelled? Did I just dream that, or perhaps slip into an alternate reality once?
