I posted this illuminated turtle as an example of a 3D printed object.

Just to see how it looks in this forum.

My topic is a possible discussion of 3D printing as a stand alone hobby, or a tool for use in other creative endeavors. 

There (in my opinion) is no right or wrong answer. It's an interpretation of how the owner/user feels about the printer's use in what they create. 

In my reality, I believe the definition is not a static label. Newbies are totally centered on the operation of the hardware. Their Hobby is getting 3D printing to work. Once operation is mastered (to some extent) it becomes the tool for making stuff. The hobby becomes what is being made. 

My hobby is making plastic JUNQUE via 3D printing. <G>
