Question 1: there has been so many awesome things created by 3d printers, for parents making toys for the kids, to role praying models, even to hats and shoes, to making a working model of an idea you have for anything to show a board room meetings to get funding to create that product on a mass scale. So how could I even think of what what is the most interesting thing when it all is because someone had thought of it to make it and to them it was special.

Question2: if I could have any kind of 3D printer, I would have to say one that is easy to learn to use it and can be easily taught to children since they have a more active imagination than most adults and it would be wonderful to see what they would come up with that the future might need when they are taught 3d technology at young age.
