Small holes were also automatically filled using the software’s hole-filling algorithm. Using Artec Studio to create and control the mesh generated from the aligned scans allowed us to extract the exact level of detail we wanted for manipulating and 3D printing.”Īnother feature enjoyed by the TPI team was Studio’s filtering capabilities which removes all elements smaller than the master scan, freeing all exported meshes of artefacts. “Aligning each scan was as simple as manually orienting to a loose approximation of the correct position and letting the alignment tool refine the fit to perfection.
“The dimensions and surface details needed to be close enough to what we would get from a silicone mould so that we could hand-finish 3D prints to look exactly like the original specimen. “We needed to three-dimensionally digitise the skeleton that could not be dismantled so that a replica could be 3D printed,” said Matt Christopher, TPI. TPI says the alignment features within Artec Studio were paramount to the success of the project. Once scanned and uploaded to Artec Studio, the data was aligned, cropped, and converted to 3D mesh files. Those numbers would have been even higher, but a decision was made to skip scanning bones that could instead be mirror imaged, like the arms, legs and ribs. By the end of the scanning process, the team had 629 individual scans across 71 individual scan projects sitting inside the Artec Studio software.
Using the Artec Spider 3D scanner and the Artec Studio processing software, TPI was able to scan individual bones and regions of the skeleton and upload them as individual projects in Artec Studio.

The final model of the Kessler Stegosaurus in Artec Studio, side view Moulding in silicone was pretty much impossible, but scanning in three dimensions wasn’t. Steel was shaped around the skeleton, welded in place and permanently puttied to the bones. The team had to negotiate the sheer size of the skeleton, but also the fact that the carcase was mounted on its exhibit with no forethought of it needing to be removed when it was installed in the 1990s. TPI, with the approval of the museum, got to work. The grandfather of RGDE owner, Zach Reynolds, would regularly join Kessler on dinosaur digs from the 1940s through the 60s, and so RGDE wanted a copy of the Stegosaurus that was discovered just a few miles down the road and had family and community ties. Mike Triebold, President of Triebold Paleontology, wanted to add the famous Kessler Stegosaurus to his catalogue of casts, and the new Royal Gorge Dinosaur Experience (RGDE) in Canon City also wanted to feature it.

It weighed up to 10 tonnes when it roamed the area now knows as Colorado 150 million years ago, and its remains were eventually found in 1936 by a class of high school students, taught by Frederick Carl Kessler, who would go on to help professional palaeontologists in excavating the fossil.
The 26-foot-long, nine-feet-tall skeleton represents Colorado’s State Dinosaur and appears in the museum alongside the frame of an Allosaurus. Triebold Paleontology, Inc (TPI), a provider of fossil-related services, has harnessed 3D scanning and 3D printing technology to produce a 1:1 scale model of a Stegosaurus skeleton displayed at the Denver Museum of Nature & Science.
