The majority of Bone Clones® are created by making molds of original bone material, but a small number of our products have been developed using 3D scanning and printing techniques. Click Here for More Information. This category is a collection of all Bone Clones® that originated from those methods. 3D scanning and printing techniques now allow us greater flexibility in the types of new products we can develop. These include skeletal and soft-tissue models made from CT scans of living persons, and casts of specimens that are too fragile or small to be molded using our traditional methods. This also allows us to scale an object up or down. Examples of scanning methods we employ include medical CT and MRI imaging, micro-CT and nano-CT scanning, 3D surface scanning, and photogrammetry. Scans are digitally processed and 3D printed, then those prints are meticulously hand-finished before being molded using our traditional methods, cast in our custom polyurethane resin, then painted and finished by hand.
