I don’t own one, but my brother has a Peachy 3D printer. 3D printer is a fantastic machine; since my brother has his own small jewellery shop in town, he uses additive manufacturing as an efficient way of producing one of a kind design of accessories like necklaces, rings, pendants, and bracelet and so on. He uses wide range of materials such as ABS, PLA, and nylon filament. And just recently, he’s fond of utilizing rubber-like material like this http://www.3d2print.net/shop/3d-printer-filament/elastic-filament/ which he used for my personalized iPhone case as a birthday present. Now, he’s making big profit out of it (I'm proud of him).
