Make it Stand!

Make it Stand is an application, yet to be made available to the public, that allows users to modify any 3D model in such a way that, when printed, its center of gravity will ensure that it balances perfectly. 

The official publication:

Our approach combines stability objectives with shape preservation measures in order to respect the user’s original design, whilst making it feasible without the need for aids such as an oversized base or the addition of stilts. We introduced a novel algorithm that leverages the use of interior voids to manipulate mass distribution without affecting the exterior appearance of the model. We alternate between interior carving and shape deformation to arrive at a final stable result. We have demonstrated effectiveness with numerous results including character models and everyday objects, many requiring particularly delicate balance conditions to stand in equilibrium. Further, we extended our technique to objects that stand on multiple bases.
