As an artist you are able to make stuff you were not able to make before but it also means that as just a common everyday person you can start to make art of your own and also to make tools that can be designed specifically for your lifestyle. With that said using a 3D printer also has the risk of turning into a device that you use only to print out useless trinkets on most of which get thrown away very often. So for me when using a 3D printer there is a very thin line between a user and a maker, a maker being someone who makes their own tools and a user is just someone who uses the printer like one would a toy before ultimately growing bored with it.
