This just arrived from i.competitive service. The model is hosted on Shapeways and has been ordered (and rejected) many times by shapeways reviewers, despite printing on my own printers just fine. While I can print my own models, many cannot and finding a reliable service has become a goal of mine. This particular print came out very nicely and with none of the rejections that have become a staple of Shapeways. So, for anyone struggling with strange, incomprehensible, or inconsistent errors from Shapeways review staff, I recommend looking elsewhere. This was printed at i.competitive service. I will try Ponoko next and post my experience with them. I specifically post this as I have noticed that Shapeways is losing designers to these reviewer gaffs; for example it looks like Dizingof has removed everything from this site and moved it all over to Thingiverse, Ponoko, and imaterialise. This print was 40% more expensive at imaterialise than the Shapeways quote, but I'm willing to pay more for something than less for nothing, and it seems others feel the same way. I certainly hope the Shapeways Rejection Process is revamped soon, as I really do prefer this site's storefront and overall presentation... but in the end it's the product and not the store that people care about.
