Hi everyone! I am doing my graduate research about the trends among 3D printing and modelling users, and I would like to know more about your knowledge and experience with the technology. Here is a 2-minute survey on the topic, your participation is really appreciated.
If you want to know more, please message me

the questions don’t seem to be worked out well and hardly serve any realistic academic paper.
You clearly haven’t learned how to conduct studies and how to properly phrase questions without influencing your audience.
also " Would you try free and user-friendly 3D modeling programs such as 123D apps, Blender, Google Sketchup, 3Dtin or Tinkercad?"
Blender is very, very far from being user friendly.
I can’t agree with what you say, but I accept your point about Blender. Thank you for your time.
Well you’re asking suggestive questions.
There is no way offered to not answer some questions.
The questions don’t tell much about trends are they don’t relate to time at all.
Modelling is hardly covered.
What’s the exact topic of the diploma thesis and who’s your professor?
