These are The 3D Printing ETF's own holdings, not the firm's. Percentages are of the stock positions in its latest filing — the fund's cash and bonds are not included. A fund that owns the machines that build layer upon layer of plastic, metal and carbon fiber, along with the software that designs those parts and the materials that feed them. Launched by ARK Invest in July 2016, the 3D Printing ETF buys companies on all sides of additive manufacturing rather than betting on a single printer maker, spreading its money across hardware builders, computer-aided design and printing software, raw materials, and the shops that print finished components for other businesses. It is the one member of the ARK family that is not actively managed. Where sibling funds like ARKK and ARKG pick stocks by conviction, this one rides a rules-based index called the Total 3D-Printing Index, which tiers its holdings into fixed business-line weights — printers get roughly half the portfolio, software and design tools most of the rest — and rebalances quarterly. The index reaches beyond U.S. shares into other developed markets and Taiwan, home to several of the industry's parts suppliers. William Scherer, a member of ARK's management team, oversees the fund's adherence to its index. The fund launched on July 19, 2016, under ARK Invest's roof, and is run out of the firm's St. Petersburg, Florida headquarters. ARK's broader thesis is that disruptive technologies compound in value over time, and this fund is ARK's narrower bet that additive manufacturing will follow that curve — betting on an industry that is still young and has yet to settle which materials, machines, and design tools will win.
The 3D Printing ETF opened a new position in American Axle & Manufacturing Holdings and exited Dowlais Group. It substantially increased its stake in Velo3d while sharply reducing Titomic and Evonik Industries. The fund also trimmed a broad swath of industrial and software names, including Siemens, Autodesk, Dentsply Sirona, Renishaw, Bico Group, HP, Materialise, Proto Labs, Nano Dimension, Straumann, Nikon, and Kaiser Aluminum.
