I am very excited about 3d printing applications but know absolutely nothing about how it works. Where should I start learning about it?
Reprap.org is where I learned the ropes… Depends on what you want to learn, about the printer itself so you can upgrade and fix problems and know everything about it? If so http://reprap.org is the place…
More interested in getting a printer, using software and making stuff without worrying about how it works, http://reprap.org may have some information to help you but I don’t know of anything purely for that side of things…
