The London Science Museum, whom we visited recently, is displaying a huge collection of 3D printed objects in their "3D Printing The Future" exhibit. That massive collection is apparently not sufficient for them, as they've launched a new Tumblr blog for folks to post pictures of their best 3D prints.
And what a set of designs you can see!
While there are a few "basic" 3D printed objects, there are many very complex designs and frequently they've been finished in unusual materials or paints. We're particularly fascinated by several suits of Japanese armor that currently top the list.
A good place to see great designs - and submit them if you have some.
