As long as I visit reprap.org, I learn more and more from reprap.org
I knew reprap.org at the end of 2009. I built some PCBs such as GEN3. Then I bought one Cupcake CNC from Makerbot on 2010. Then I had built my own 3D printers. Yes, it is a long story. But now, I try to put my work into RepRap.org. That ‘s a exciting thing for me.
I designed the K Extruder(http://reprap.org/wiki/K_Extruder). And, I am working on the Pangu.
Pangu is a Prusa Mendel i2 with LM8UU liner bearing and K Extruder, coming with the Melzi electronics, include some tools and anything else needed for a working 3d printer. Prusa Mendel is simplied version of Mendel form RepRap project. RepRap is open source 3D printer.
Chinese legend said Pan Gu created the world by separating the heaven and the earth from chaos, use his axe. In my mind, 3D printer is a tool, like the axe. 3D printer can change the world, too.
