3D printing is one of those things that I’m not quite sure if I believe in. I mean, sure, I’ve watched videos of the devices printing, and yes, I’ve held physical objects that have been printed. But still, come on, it doesn’t sound very realistic, does it? Via Alice Taylor, who is currently creating a business around the mystical world of such printing (gratuitous plug for my podcast interviewing her and Cory Doctorow), comes a video of MIT students figuring out a way to print 3D objects created in Minecraft. And via that comes a video of someone printing 3D objects within Minecraft.
