I've been trying to stay out of these discussions as I know there are a lot of makerbot fans here and don't really want to get into flame wars with them. However, the recent patent filing revelations are getting my ire up once again. The best way to show our disgust for makerbot greed is to stop buying and using their products. Please support open source printing. Printrbot, Tantillus, Lulzbot, Mendel90, and many others continue to embrace these ideals. There are also many other companies selling open source parts and kits such as MakerFarm and others selling Prusa designs.
