I started CNC in 2002, took it in 7th grade and Jr/Sr year of high school, I had a roommate with his own CNC business in 2011, his financing payment on his largest table was twice that of his mortgage. The market needs more CNC, especially in growing areas with lots of new developments going up. CAD/CAM/3DP is the absolute most efficient method for inventing, design & invention will never go away, there is ALWAYS a need for skilled freelance 3D modelers as well. It’s a great way to make money if you know how to market, and if you’re first in a market. My area needs a good CNC shop.
