I've seen a couple of people that posts 3D printing new articles on steemit, but they are just that - news. It does not mean that the person is interested much in the topic itself. For me 3D printing is just one of my hobbies and a topic of interest, even though I like to read, write and experiment with it I'm not all about 3D printing :)

I think they are interested but your posts are much better.
