Based in Bratislava, the Pressburg Mint of Slovakia is using cutting-edge technologies to breathe new life into the city’s centuries-old tradition of minting coins. To enable these efforts, the private company has purchased two X1 160Pro metal 3D printers from binder jetting expert ExOne. The printers will specifically be used to make silver investment coins as well as high-performance steel parts for other industries.
Bratislava’s coin-making tradition dates back to the early 15th century, when it was granted the right of coinage. Over the next centuries, the city would mint coins for the Holy Roman Empire and the Austro-Hungarian empire. In the 18th century, however, the city’s minting activities largely ceased. Until now, that is.
The Pressburg Mint will utilize its new ExOne 3D printers—the largest of the company’s metal binder jetting systems—to produce numismatic coins and silver investment coins. In fact, one of the X1 160Pro systems will be exclusively dedicated to processing Silver 925. One of the first minting projects for the 3D printer is a series of ultra high-relief silver coins featuring a crowned lion. The coins, which have a mirror finish and blue diamonds, will be showcased at Formnext 2021 next week.
The other system purchased by the Pressburg Mint of Slovakia will be used for printing 316L stainless steel and other materials. This system and the precious metal 3D printer are also available as a service through the mint’s newly launched Printy division. Printy will operate the new 3D printers and work with external partners to produce and deliver metal parts.
“Our two X1 160Pro systems will allow us to take our designs to the next level with full production scale metal 3D printing in Central Europe,” said Radoslav Behul, CEO of Printy at the Pressburg Mint. Traditional minting and coinage techniques have limitations in terms of creating three-dimensional designs, so the use of additive manufacturing will truly unlock a whole new world of design opportunities for high-relief and 3D collectible coins.
