Abstract: A network system can optimize 3D models for 3D printing. A smoothing operation can be performed for a 3D model that comprises a plurality of voxels by identifying exterior voxels of the 3D model. For a first exterior voxel of the 3D model, an exterior surface orientation can be determined and a smoothing operation can be performed based on the determined exterior surface orientation. The smoothing operation can include performing a triangulation operation based on the determined exterior surface orientation of the first exterior voxel. Furthermore, in response to determining that a dimension of a set of voxels is below a threshold limit, one or more voxels can be added to the set of voxels to satisfy the threshold limit.
