An interesting video from Objet shows off many of their latest materials. While many Fabbaloo readers have 3D printers capable of printing in hard plastic, the items in this video demonstrate what can be achieved when you are able to print in flexible material.
Oh, did we say that Objet has an almost perfectly clear material, too? You'll see that in the video.
Someday such materials may be available to personal 3D printer owners, but for now you'll have to use Objet's technology.
