Articulated 3-D-Printed Hand (image) Harvard University Share Print E-Mail Caption A new software tool translates animated character skins into action figures that can be produced on a 3-D printer. The software uses a series of optimization techniques to generate the best possible model, incorporating both hinges and ball-and-socket joints. It also builds some friction into these surfaces so that the printed figure will be able to hold its poses.
