I'm using Shapeways as 3d printing service since long time. I've always had a good print quality and when it was not the case I was always able to request a reprint or a refund. Customer service is always ready to respond and help quickly. There is a lot of space for improve of course, as for example more constant pricing, possibility to organize 3d models differently. A B2B would be very appreciated, with the possibility to pay afterwords and to contact the team directly for specific requests. I will add some extra finishing for precious metal as for example sand blasted or brushed effect and do not work with a minimum price. If you design jewelry they are most of the time very small pieces, and with a minimum price you pay more for a small piece that for a big one. The indicated delivery time is most of the time longer that effective one, which is normally faster. Price - quality is okay if compared with other platforms.
