Independent review finds SupaVoxel outperforms Tripo AI in 3D model generation test

An independent reviewer tested two AI 3D modeling services, Tripo AI and SupaVoxel, using the same source image of a skull ornament. The reviewer generated models using each service's default settings and analyzed the resulting files for printability.
