Two-year-old Emma wanted to play with blocks, but a condition called arthrogryposis meant she couldn't move her arms. So researchers at a Delaware hospital 3D printed a durable custom exoskeleton with the tiny, lightweight parts she needed.
"To the best of my knowledge, this is the first 3D printed firearm in the world to actually be tested." Gentleman describes how he used an old 3D printer and CAD files to print his own working gun.(*)
RepRap is a self-replicating rapid prototype machine (3D printer) using fused deposition modelling. You can build one, although I'm not sure why you'd need to....
