Hi, I'm new to using Shapeways and have not had the opportunity to handle a single object yet. But I am confused about how to go about doing my project. I'm not sure how Shapeways will print my model ring in stainless steel. I want to (in the model) place an etched style engraving, so that a 3d picture, word, or such can be seen on the ring's face. Of course, to save on money, this will not be pulled out of the face, but pushed in, resulting in less volume. However, a ring is small, and the design rules state that a wall thickness of 1mm must be observed. If the engraved design makes the inner wall of the ring smaller than 1mm, but the <1mm wall is surrounded by >1mm walls, will that be okay? Or is it a hard limit? A printer dot size? I would need to do a ton of research to complete this project and I am on a deadline of only a few months. If I cannot complete this design by then I must turn to other methods or materials offered, but I would prefer to use stainless. Also, the detail of the engravings is important as well, will the 90Ëš edges remain sharp after printing, or will there be a bezel introduced into the model? If it does remain 90Ëš, how close can the engravings sides be. For example: If this were the flat ring face OOOOO OOOOO OOOOO OOOOO OOOOO would some parts of this engraving be flat after printing, or still show the lowered/engraved design? (dots here) OO.OO O.O.O .OOO. O.O.O OO.OO Short Version: Can wall thickness on a small ring of <1mm be possible if it is only for a small region of the product. What is the engraving limit of stainless, will the small gaps required be filled after printing, detail levels?
