3D printing is often seen as a futuristic manufacturing tool, but it's also proving to be a powerful asset in archaeology. Today, historians and researchers are starting to take full advantage of this fast-developing technology. Recently, Australian archaeologist Billy Ó Foghlú from the University of Canberra used 3D printing to restore a damaged historical artifact. What he discovered was truly groundbreaking—his 3D-printed replica revealed that what was once thought to be the tip of an Irish spear was actually part of a musical instrument.
The original artifact, known as Navan’s tapered spear tail, was found in Ireland in the early 1900s and is believed to date back between 100 BC and 200 AD. For years, it was assumed to be a spear tip, especially since archaeologists in the past focused more on warfare and dynasties rather than cultural or artistic aspects. But with the help of 3D printing, Billy was able to create an exact replica and test its function.
He scanned the original piece and printed it using a 3D printing studio in Sydney. Then, he used the 3D print as a mold to make a bronze copy. “It only took me a week to complete it, and it looks almost identical to the original,†he said. He also created a replica of a horn that was part of the same set. “It was over two meters long, and I even simulated the metal thickness. When I attached the ‘spear tip’ to the horn and tried to play it, something amazing happened.â€
Suddenly, the instrument came to life. Not only did it feel more comfortable to use, but it also produced a much wider range of sound. This proved that the object wasn’t a spear tip at all—it was actually a mouthpiece for an ancient horn. Such instruments were common in Europe during the Bronze Age, but very few have been found in Ireland. This discovery suggests that music may have played a more significant role in Irish culture than previously believed.
“These horns weren’t just for hunting or making noise. They were carefully crafted and often played for long periods. Music seems to have had a deep cultural significance,†Ó Foghlú explained. His findings were recently published in a research paper, shedding new light on the musical traditions of ancient Ireland.
