  • Patent number: 10239229
    Abstract: Systems, methods, and computer-readable storage devices for scanning a retrieved geological core sample to produce a digital file representing the core sample. Then the digital file is transmitted to a three-dimensional printer that can execute the digital file to make a geologically, chemically, and structurally equivalent replica of the retrieved geological core sample. The three-dimensional printer can optionally combine a base geological material with one or more additives or with an inert binding agent layer by layer as three-dimensional pixels. The replica core sample can then be used for testing or for other purposes at a greatly reduced cost than retrieving multiple actual core samples. Further, the replica core sample can be reproduced at virtually any location rather than transporting an actual core sample.
