Can be true but like all things it depends. In the 6 years I’ve been into 3d printing I’ve observed that lots of people compulsively mod their machines. I just print stuff. Filament is cheap and I use free online software to do designs. The repair parts I’ve made have actually paid for the machine by being able to keep broken stuff instead of replacing them. But I’m cheap. I think people who are determined to spend money will find a hobby to spend it on.
