In one implementation, a system for using a scan recommendation includes a receiver engine to receive a plurality of pictures of a three-dimensional (3D) object from a scanner, a model engine to generate a 3D model of the 3D object by aligning the plurality of pictures of the 3D object, an analysis engine to analyze the 3D model for a volume, a shape, and a color of the 3D object, wherein the volume, the shape, and the color analysis is used to generate scan recommendations, and a display engine to display information relating to the scan recommendations based on the volume, the shape, and the color analysis of the 3D model of the 3D object.
