I would use "3D printers" as a search term and start researching from there.
I compare this to around 1980 when personal computers were just starting to move beyond hobbyists and geeks. Most people still scoffed at the idea that average people would want to have a personal computer at home. They still saw computers as room sized machines operated by men in white coats. But for those who saw the applications and the potential of a home computer, they were amply rewarded.
Thanks for the advice and not a problem at all. Any is appreciated.
