I can kind of see their point of view if their knowledge of the 3D printing world is go search on MyMiniFactory, download, print, cosplay. That's definitely easy mode.
Where I get mad is when people say, "Oh you just printed that?". No, I didn't just print it. I spent 5-10 hours preparing a digital model based on an obscure screen shot, used knowledge I've built up over years on how to best print it, smoothed and sanded it for another god knows how long, added electronics and then painted it over the course of several days. There's plenty of skill required to make a printed piece look good and it's time consuming to do it just like any other craft. Just because I get a machine to precision build a part doesn't make any part of this easy. If it looks easy, then I must be doing my job well. </rant>
