Abstract: Techniques for evaluating support for an object to be fabricated via an additive fabrication device are provided. In some embodiments, a three-dimensional representation of the object is obtained and a plurality of voxels corresponding to the representation of the object is generated. A first supportedness value may be assigned to a first voxel of the plurality of voxels based on an amount of support provided by a support structure to the first voxel, and a second supportedness value determined for a second voxel of the plurality of voxels, wherein the second voxel neighbors the first voxel, and wherein the second supportedness value is determined based on the first supportedness value of the first voxel and a weight value representing a transmission rate of supportedness through voxels of the plurality of voxels.

Abstract: Techniques for generating a support structure for an object are provided. In some embodiments, one or more regions of the object are identified as one or more regions to which mechanical support is to be provided and one or more support points within at least a first region of the one or more regions are identified. A support structure may be generated for the object that comprises one or more support tips coupled to the object at the one or more support points, where the support tips being generated based at least in part on a direction normal to the surface of the object at the respective support point. Techniques for providing visual feedback to a user relating to an amount of support that a support structure is expected to provide during fabrication are also provided.
