3.1 - Drugs are hard to control as well, but we still have laws to do so. What kind of ban or legislation might be attempted? Think like a congressman.
3.2 - There are probably some more projects around here which you'd enjoy fighting with then. I'll try to keep an eye out, but don't be afraid to look around for what you can make better.
3.3 - Would iTunes be as affordable if there weren't means to obtain the music for free? On another note, couldn't someone become famous for their designs by giving them away for free much faster than by charging for them?
2.1 - Instead of replicating the threaded rods, could we re-design around them?
As discussed in class we could make a solenoid; however, I think so much precision of the machine is used from threaded rods in the motors that replicating them with another printer would affect how accurate the printer will be.
2.2 - Does having access to a printer like this make you feel more enabled?
Yes it does, I feel that with the use of this it will allow many easier operations being able to be done with a 3d printer instead of milling metal or other methods of manufacturing.
2.3 - Have you considered the extruder as an application? We can create other 'apps' in it's place, with little modification. Does that give you any other good ideas?
I have not, I think that would be a good idea. We could use pencils, stencils, or other things to make the REPRAP machine more usuable. For instance, growth of DNA as discussed in the movie presented in class.
1 - Why can't you use a plastic washer?
You cannot use a plastic washer to replace a metal one. The properties of the washer would decrease drastically, and if was used for tightening a metal nut, it would dig right into the washer. There could be for a plastic washer, but it looked as if they copied a metal washer, for prototyping purposes of a metal washer.
