Normally you’d select one or more likely companies and simply buy their public stock from an exchange. Can you do this in the world of 3D printing?
The answer is “sometimes”. If one were to look at the world of 3D printers today you’d find several types of entities involved:
- Open source projects, like RepRap. These operations aren’t necessarily companies, let alone something you could invest in, other than donations.
- Small companies, like MakerBot. They’re privately owned and unless you know someone you’d have a hard time making a real investment. But investments do happen, as MakerBot recently received a massive USD$10M injection.
- Private companies, like Objet or ZCorp. They’re big. They have (presumably) big profits. But you can’t invest in them, as they are private. No stock offerings here.
- Public companies, such as 3D Systems or Stratsys. Yes, you can invest in them! They are public companies offering stock that trades on major exchanges. But here’s the catch: only these two 3D printer manufacturers offer stock. You may choose one or the other. Only.
There is another investment possibility: invest in related products and services that aren’t actually 3D printers. But that’s a post for another day.
