Closest I have found is ROBO (Robo-Stox Global Robotics and Automation Index ETF) which has about 7% of its composition in 3D printing stocks. It does have a hefty expense ratio of about 1%, which is not worth it IMHO.
The U.S. Market could surely use a tradable 3D pure play investment vehicle. In the meantime, we just create our own 3D portfolio by buying the companies directly. You can use the SXG3DPP index Gary linked to for keeping up with newer components... although i'm sure we'll hear about them sooner on this board as well as through www.3dprintingstocks.com ;-)
STOXX has launched a second ETF (Exchange Traded Fund) this week aimed at 3D printer investors, with the catchy name of Global 3D Printing Pure Play (SXG3DPP). This new fund is a pure 3D printer play, as opposed to the previous fund (STG3DPP) which is invested into companies that have a source of income related to the industry (at least 1%). For those that are new to ETF’s, they represent a way of investing, or trading a particular index. There are a multitude of permutations of this basic premise, but in this regard the fund will be solely devoted to investing into the said companies (or components). There is a degree of weighting to one company or another dependant on market capitalisation, or other factors.
Interestingly, the fund has ambitions to invest in 30 listed companies which are purely 3D printing orientated. I have a feeling this is going to be difficult at the moment, especially as their inclusion criteria is quite restrictive. STOXX can select companies from 65 countries, which have in their opinion valid stock markets. They have selected ten companies so far.
If you do not like the idea of a fund, then you can always select your own companies to invest in directly. Here is a selection of my favourite 3D printer companies;
