Researchers from the McKelvey School of Engineering at Washington University in St. Louis have developed a machine learning algorithm that can create a continuous 3D model of cells from a partial ...

These Primitives can also serve as synthetic database of annotated models, of which there is a dearth of in the 3D CAD industry.

To sum up: 3D scanning makes 3D models from real-world objects, but the models that come out of the scanning process aren’t necessarily suitable for engineering purposes without additional work.
