world's first store for 3D printed goods just opened in Brussels, and while we imagine they've already got a fair selection of prototyped merchandise to choose, might we suggest they invest in a few production runs of this fabulous new flute? Amit Zoran of the MIT Media Lab -- yes, the same soul who helped dream up a 3D food printer early this year -- has now printed a fully-functional concert flute with a minimum of human intervention. Directing an Objet Connex500 3D printer (which can handle multiple materials at the same time) to spit out his CAD design, dollop by tiny dollop, in a single 15-hour run, he merely had to wash off support material, add springs, and assemble four printed pieces to finish the instrument up. The proof of the pudding is in the eating, of course, so how does it sound? Find out for yourself in the video below.
