3D Systems basically buys American 3d printing companies then shuts down the factories.
I have some experience in this area.
1. It's very unlikely you can get that reaction from them. These companies generally have management that is comfortable and basically asleep at the wheel. And they are cocky about their expensive products.
2. If you do get a reaction, it will be because you got the attention of someone they care about, investors, board members, press. These are fickle and they won't respond to details about your product.
3. If you do get their attention, they will likely respond with anger, patent lawsuits, etc, not by showering you with money.
(This is how we ended up getting sued by 3D Systems months before we shipped a single product, based only on a Kickstarter video)
