3.1 - What about brute-force legislation, requiring some kind of controls/restrictions?
3.2 - I think we need a solidworks version of our printer. Does that sound interesting to you?
3.3 - Good designs can make a name. Look at Prusa. I don't know that you'll get rid of people who are trying to enrich themselves though... IP is often less about recognition and more about money, so do you really lose recognition for design work with open IP as opposed to closed IP?
2.1 - There are some tricks that one might apply though, right? You could create several extruders designed for different materials, which might somehow get around the problem. You can create plastic parts which you then cast into metallic ones, employing other low-tech methods to enhance what the system CAN do. You're right though: there are big issues to overcome. See here: http://reprap.org/wiki/Actuator_Fabrication
2.2 - You will ultimately hit a wall in terms of the number of printers. I believe someone did a calculation based on the number of arduinos and stepper motors in production once.....
2.3 - Computers followed a similar trend. Perhaps it is the ability to do it in your own garage which helps push companies to provide competitive products? Certainly this has worked out well for the PC market.
I hope you don't mind me commenting here. I noticed you are in Allentown while looking for any RepRap activity in the area. We're looking at doing a RepRap at Make Lehigh Valley. If you haven't heard about it, you would be welcome... http://makelehighvalley.com --Flickerfly 04:55, 30 January 2013 (UTC)
