Do you remember Ötzi the Iceman? A caveman who died 5,300 years ago, he was discovered in 1991 by a pair of hikers on Tyrolean Alpine peak in northern Italy. To prevent additional decomposition, he was rapidly locked away in a freezer in Italy, which created it complex to study him. That’s why US paleo artist Gary Staab not long ago teamed up with Materialise to 3D print medical-grade replicas for display and research purposes. Their work is now fish, and three Ötzi replicas are set to travel to the US: one to the North Carolina Museum of Natural Science, and two additional can go to the Cold Spring Harbor DNA Learning Center in New York (DNALC).
Ötzi the Iceman’s story is really astonishing. Upon his discoreally, he became an overnight media sensation for being one of the most naturally preserved mummies at any time discovered. Recent forensic evidence announced he was in fact murdered by an arrow on a lonely mountaintop at around the age of 45. The caveman, who was 1.6 meters (or 5’3”) tall and weighed only 50 kilos, was discovered with clothing and equipment (which include a copper axe and a bow and arrows) on his man. His last meal consisted of venison and ibex meat, and he was lactose intolerant, arthritic and infested with parasites. Remarkably, he was in addition covered in 61 tattoos. All this data obviously reveals really a lot of bronze-age life, and it is believed Ötzi holds a lot additional information we don’t understand of yet.



Below: an earlier version based on the Ice Man.
But which information is complex to reach. But virtually all cavemen have only decomposed like the rest of the world around them, Ötzi was miraculously preserved in glacial ice. Upon his discoreally, he was locked in a frozen crypt in Bolzano, Italy, to prevent additional contamination and decomposition. This was necessary but unlucky, as it sat any timeely limited research and educational opportunities. That’s precisely why paleo sculptor Gary Staab was given the opportunity to manufacture medical-grade replicas.
To realize this ambitious project, the Ice Man’s body was initially scanned via a CT machine – yet a few body parts were missing. These parts, which include a few of the ribs, were painstakingly filled in by Materialise’s versioning engineers by mirroring other body parts. “The reconstruction of the hands was in addition a challenge, since they may not be captured on CT scans,” introduced the spokesman of the South Tyrol Museum of Archeology in Bolzano, northern Italy, where the final versions were announced.


But this whole system wasn’t without its challenges either. “When I tried putting him back together of the scanned slices, the pieces didn’t seem to match,” recalled project engineer Eric Renteria. “So I did a few research and discovered his total height and compared which to the total height of all the pieces I had reconstructed. Once I saw which there was a mismatch, I moved his head piece into the correct spatial location, which announced which there was a gap missing.” As can be seen in the clip at a lower place, Materialise subsequently 3D printed the replica on their biggest stereolithography 3D printing device.
The final versions were and so fishd by Staab. “Materialise system-segmented all of the scan data, created a rad accurate print, and I was able-bodied to add the details over the top of the print to turn it into an accurate, life-like replica of the original. It was another rad 3D collaboration with Materialise and its team of engineers,” Staab said of the project.
The 3D printed versions are aleager houtilized in the South Tyrol Museum of Archeology, but are eager to go on tour. The initially Ötzi is set to become part of a travelling exhibition which can tour throughout North America, beginning in the North Carolina Museum of Natural Science in Raleigh in October 2017. The other two versions, meanwhile, can become educational tools at the Cold Spring Harbor DNA Learning Center in New York (DNALC). Hopefully, they can be able-bodied to reveal a lot additional of life, death and humanity at the eve of the earliest civilizations.
