3D printing refers to the process of creating three-dimensional objects. Theoretically, almost anything can be “printed,” ranging from a slice of pizza to electric cars.

PRNT is the first ETF to track an index composed of stocks that are directly involved in 3D printing and 3D-printing-related businesses. Those businesses include printing software, hardware, printing centers and scanners. The fund is roughly two-thirds invested in U.S. equities and one-third in overseas markets (mostly Europe), but could expand its holdings to several Taiwanese technology companies.

Drawing strength from the inherent push for technological advancement around the world, managers of PRNT are expecting 3D printing to revolutionize manufacturing. As the technologic basis for 3D printing gradually enters a more mature phase, some analysts estimate that 3D printing soon will appeal to a wider audience, which would be excellent news for PRNT.

In September 2016, General Electric (GE) spent $1.4 billion on two large acquisitions of 3D printing companies Arcam and SLM Solutions. GE also plans to bring 1,000 3D printing machines online over the next decade in a huge commitment.
