It depends on the 3D printer, but in most cases, you don’t need to be super technical to use one. You’ll need to be able to download 3D printing plans from the web, load them into your 3D printing software, and send them to be printed, much like you would send a document to a traditional printer. If you’re worried the process will be too challenging, get a 3D printer with a touchscreen. These printers are simpler to interact with, so you spend less time planning and more time enjoying the objects you print.
