Another reason is the price of the 3D printers. You may say that someone somewhere has created a 3D printer using an ordinary projector and spent $50 on the other parts but this is not really the case I want to discuss here. Most of the good 3D printers cost a lot of money and many people cannot afford them (of course, there is always the option of applying for another loan).
The good thing is that it is not necessary to buy a 3D printer, you can just type “3D printing service” into Google and see a list of websites where you can choose a 3D model and order to print it. I like 3D Hubs the most. Sometimes you may literally find another 3D hub right next door.
