It seems a new iPad application is now available for amateur CAD jewelry designer! With iRing its possible to create and shape your ring design into a printable CAD model .
"Shocking and amazing. Creating something on the iPad, instead of absorbing the limitless digital content, browsing design variations instead of movie options, sending in an order of that design to be printed instead of sending in orders for a large deep-pan pizza. The iRing3D iPad app has done it. It’s all simple and quite basic – drag some points, adjust, send to Shapeways or Sculpteo for your own 3D printed jewelry creation. However, there’s an interesting aside that foretells a bit about creating designs on mobile touchscreen devices and perhaps about CAD interfaces themselves."
