A new study from Disney Research describes a method for 3D printing objects that are capable of balancing in one or more stable positions thanks to metal balls embedded within hollow cavities or "capsules" in the print. With a software system the team is creating, the user would design a model as usual, but also indicate the different ways the object should stand or balance. The algorithms would then use those parameters to add one or more hollow capsules to the design, their shapes, sizes and locations automatically calculated and optimized. While printing the object, the user will need to pause the process to place the ball bearingss into the capsules, and then continue. When the print is finished, the object should easily balance in one or more positions, exactly as the designer envisioned.
