I was wondering about the minimum wall detail on different materials, from 1mm on up. Sometimes it is frustrating to meet this pending the project someone is working on. If I understand correctly, the minimum wall detail is to protect the customer from making something that would generally be considered too thin or weak. If so, I was wondering: Would it be possible to get the customary email explaining that the walls are too thin etc with the pictures showing the bad points. BUT, instead of saying it cannot be printed, what about giving the customer two options? 1. Redo your file to meet the minimum. 2. Take your chances and print the file. If you do this, Shapeways is in no way, shape or form responsible for the printed result and will not offer a refund/replacement for said model. This way it is an oral consent to "roll the dice" so to speak. I may be mistaken, but it would take no additional implementation or work on your part and would let customers experiment as they wish? I thought of this as I have come into this issue on model I am working on where I would REALLY like a part to be .5mm thick but 2mm wide. I understand the minimum and why it is in place but I figure would it be bad to let us experiment at our own cost if we so desire? Thanks, just a thought I had.
