The 3D printing model marketplace called Threeding.com has announced a couple of new added features which should make the buying, selling, and downloading experience a much more secure, enjoyable process. The first feature is their 3D Printability Check which will optimize models for printing, correcting any issues they may have, and when done give the object a certification. The second is a new 360 degree view of models. The full details on both these updates can be found here: http://3dprint.com/12210/threeding-improvements/
