Comparison of open-source 3D printers
Below you will find a matrix that compares common desktop 3D printers classified as Open-Source Hobbyist & Do-it-Yourself systems. I put this together with information from http://www.additive3d.com/3dpr_cht.htm which compares almost all desktop 3D printers. Take a look at the link if you get the chance, or just focus on our world below.
