Yes, that has already happend, years ago. What I would do to look into 3D printing is buy one of the less then $200 printers and make parts. A great project is maybe a robot or a small CNC machine tool made from plastic parts. You learn best when you have a project that pushes your skills just a little. You can also combine additive and subtrctive methods. for example print, a part then treat it as casting and clean it up on a mill or lathe. Either you need an expensive printer that can print metal or you print a mold in plastic then sand cast it, then machine it. There is quite a lot to exlore at the ntersection of adding and subtracting. Another is printing fixtures for machining.
