I have too many expensive hobbies as it is. I would love one but until I can get one big enough and reliable enough to be able to make money off of it I probably won't be getting one.
I was at a robotics competition the other day and they had a 3D printer in action there. they were printing their own parts for their robots. Very cool.
I work at a community college, and I think they have one here for certain classes. I should see if I could get a play with it. Print out a 6 sided die with the Texas Flag, US Flag, Gonzales Flag, Gadsden flag or plenty of other choices....
