I’m not good enough to give recommendations, but meanwhile some questions might make it easier. What is your budget? Is open source important to you? What’s the biggest thing you want to print? Are there any special features you’re looking for? Do you want to tinker with it or rather have it “just work”?
Getting paid in money is one motivation for people, but not the only one. Some people do things because they want to, regardless of payment. And some of them want to give what they made as a gift to anyone. The flip side is that no one can force them to do anything, it’s all voluntary.
