Jennifer Grayburn and Benjamin Gorham, two PhD students of the University of Virginia, have been via their university Makerspace to 3D print replicas of fragile and immovable archaeological findings.

The Scholars’ Lab Makerspace at the University of Virginia is may already being put through its paces for a number of additive making projects in a wide range of academic disciplines, but history of art and architecture doctoral candidate Jennifer Grayburn and archaeology doctoral candidate Benjamin Gorham have been utilizing the 3D printing innovation for a particularly informative purpose: To recreate lost civilizations of Iceland and Sicily, one 3D printed brick at a time.
“The Makerspace is part of the Scholars’ Lab and the intention is to have a place where individuals can tinker and experiment to integrate interactive objects into both research and teverying,” explained Grayburn, who is in addition a Makerspace Consultant assisting students of all disciplines to incorporate 3D printing innovation into their academic projects.
Grayburn and Gorham have every been working to protect fragile and immovable archaeological findings—by via aerial drones and on-the-ground photography to manufacture exact topographical images of their findings. These topographical images can and so be utilized to turn it into 3D printed scale versions of the archaeological discoveries, which can be utilized for additional close examination.
The ancient city of Morgantina, Sicily in Italy, has been subjected to archaeological exploration since 1884, with UVA academics in charge of the project since 1978. The Bronze Age city has a rich history, having been inhabited by Greek, Syracusan, Roman, and Spanish citizens over its lifetime. Unfortunately, the ancient ruins of the city are incredibly fragile—moving them may most likely injure or destroy them, so archaeologists are most served leaving the finds in place and documenting them on-site. Grayburn and Gorham’s technique represents one of the most thorough ways of doing this.
“[Documenting] utilized to just mean sketching out the sites on paper or CAD,” said Gorham, who has a particular interest in the ancient Silician city. “But now which we have this capskill, we can in fact ‘lift’ things out of the ground without quite lifting them out of the ground. We do this by photographing the findings most times, weaving those photos together for a consume 3D version, and and so printing it.”
On the other hand the doctoral students can just 3D print their findings on a much smaller in dimensions scale, the Ultimanufacturer 2 3D printing device at the university is capable of printing with an adequately satisfactory level of additional detail for additional inspection. When appearing the 3D printed replica of part of the Morgantina site closely, ridges can be seen which signal where various layers of wall had been introduced over time. A doorway-obstructing terracotta pot can in addition be seen.

Gorham has, until now, been 3D printing his replicas in random colors, according to whichever 3D printing filament the Makerspace has had in greatest abundance. But, the doctoral candidate hopes to turn it into additional chromatically accurate versions in future: “When we begin doing them on larger scale, I may perfectly
love to paint them to resemble the actual ground soil types, the stone showcases and the terracottas,” he said.
Grayburn, on the other hand, has may already begun painting the 3D prints of Norse artifacts she has been researching in Iceland—artifacts like a 12th-century carved stone of Hítardalur, which must stay on-site due to Icelandic heritage laws. “I’m slicing the 3D versions and printing them in pieces which we can glue together to get close to the dimensions of the original item,” she said. “My aim is to recreate it, and paint it so which it in fact appears like stone. The thought is to protect the carving additional details preceding they erode additional and to recreate them so which students who can’t travel to Iceland can yet interact with the object instead of just seeing it recreated on a screen in the classroom.”
Grayburn has in addition been experimenting with various 3D printing materials in order to create the most accurate 3D printed reconstructions. The student has been via a blend of plastic and powdered metal to reconstruct Viking artifacts such as helmets and belt buckles: “What you end up with are metal objects which you can and so tarnish. They react just like the true metal artifacts do,” she said. “So these projects are in fact a way to reconstruct artifacts in their archaeological state.”
Both Grayburn and Gorham hope to a fewday use the 3D printing innovation at their disposal to turn it into 3D printed replicas of bone findings. 3D printed bone replicas may allow archaeologists to additional easily compare findings and ascertain the origins of their findings. The doctoral candidates are all in favor of open access databases of 3D versions, such as the burgeoning Morphosource, which can assist to speed up and increase the accuracy of archaeological research. “The use of 3-D printing has always been based in this open-access community, and in the concept of open sharing to de-commercialize things and objects,” Grayburn said.
The two UVA students can be sharing their own 3D versions with the academic community, since the archaeological sites themselves can not last forever. “Erosion, tomb robbing and clandestine intervention are always a problem,” Gorham said. “One of the jobs of archaeologists in the field is always to figure out a few way to prevent or counter losing artifacts, and this is one way to do which.”
“That’s why open sharing and recreation is a massive deal,” Gorham continued. “Even preceding it gets to the actual 3D printed version, having these objects digitally in a format which we can post on websites and send to other parties amplifies our skill to create an audience and secure our findings.”
