Within anthropology, the use of three-dimensional (3D) imaging has become increasingly standard and widespread since it broadens the available avenues for addressing a wide range of key issues. The ease with which 3D models can be shared has had major impacts for research, cultural heritage, education, science communication, and public engagement, as well as contributing to the preservation of the physical specimens and archiving collections in widely accessible data bases. Current scanning protocols have the ability to create the required research quality 3D models; however, they tend to be time and labor intensive and not practical when working with large collections. Here we describe a streamlined, Batch Artifact Scanning Protocol we have developed to rapidly create 3D models using a medical CT scanner. Though this method can be used on a variety of material types, we use a large collection of experimentally broken ungulate limb bones. Using the Batch Artifact Scanning Protocol, we were able to efficiently create 3D models of 2,474 bone fragments at a rate of less than $3$ minutes per specimen, as opposed to an average of 50 minutes per specimen using structured light scanning.
