My experience with Noble 3D Printers has always been terrific. I’m really surprised to see anything negative about the company. I’ve been using their products for years, but never had any problems worth mentioning. I know that they are the only company other than 3D Systems that makes powder and binder for the Zprinters and Projets that actually works. I have tried Canada Powder, ZD-16 and Inocat, but they take all day to cure, which kind of defeats the purpose of rapid prototyping. Well you know the old saying, “If you do not have something positive to say about someone, you should not say anything at all. It just makes you look bad” Just saying.
