There’s no denying that the value of 3D printing has grown immensely throughout a wide range of industries over time, but one field I personally feel isn’t alluded to enough for its constant use of 3D technology is archaeology. The combination of 3D scanning and 3D printing have enabled archaeologists to restore vital parts of our fragile history, whether it’s a 3D reconstruction of ancient Rome or the world’s oldest ham and peanut. By implementing this emerging technology into the field of archaeology, researchers have been able to preserve extinct animals in the form of 3D printed models, and have even recreated Syria’s Temple of Bel, which was recently destroyed by the heinous terrorist group ISIS.
Now, in a new project headed by UK-based Wessex Archaeology, one research team has surveyed and recreated two historic shipwrecks above ground, becoming one of the first-ever underwater archaeological sites to be replicated with 3D printing. After investigating and scanning the wreck sites themselves, Wessex Archaeology collaborated with 3D printing firms based in Scotland and England. The team used different scanning techniques for each wreckage, and were sure to implement historically accurate colors and features into both of the 3D printed replicas.
The first 3D printed replica was a full-colored model of a shipwreck near Drumbeg, Sutherland, thought to date somewhere around the late 17th or early 18th century. This particular wreck lies about 40 feet beneath the Eddrachillis Bay, and is comprised of three cannons, two anchors, and a partial hull on or below the seabed. Though they have not yet confirmed the identity of this wreck, Wessex Archaeology believes it could be the historic Dutch trading vessel, the Crowned Raven, which was lost around the bay during passage to Portugal sometime during the winter of 1690 or 1691. For this particular wreck, the archaeologists utilized photogrammetry, which allowed them to capture a 3D model of the wreckage with its color and texture still intact.
The other ship being replicated by Wessex Archaeology is the HMHS Anglia, a World War I hospital ship that was lost off Folkestone in Kent in 1915 after striking a mine. For the WWI shipwreck, which measures out to about 100m (328ft) long, Wessex Archaeology used a sonar technique called multibeam to map the HMHS Anglia remains. The multibeam system works by emitting sound waves in a fan shape beneath a ship’s hull; the time it takes for these sound waves to bounce off the seabed and return to a receiver is used to determine depth. In order to properly color the model, researchers used historical information, which included an illustration of the ship in the midst of sinking.
“It’s been a fascinating process to transform the light captured in the photographs and the sound captured by the sonar sensors back into solid objects through the 3D printing process,” said John McCarthy, an archaeologist who undertook the 3D modeling of the wreckage sites. “We are very excited about the potential for this technology to help us to show the wider community what it’s like to visit the site without having to learn to dive or even get your feet wet.”
The Wessex Archaeology team hopes to continue surveying and replicating historical sites like these two shipwrecks, looking to fill local and national museums up with more educational and accurate 3D printed models. Now, those eager to learn about historic shipwrecks have true access to a hands-on experience, allowing them to see a part of history without ever having to dip their toes into the water.
