Long time no see. I've been on an adventure starting my own business, Citizen Scientific Workshop. We've just got some air in our wings with new products and such, and one of them is PLA 3D Printer Filament. If you visit my site, you can see all of the pretty colors
For years there have been many great versions of DIY desktop manufacturing tools, and one of the most fun to build (and watch while it prints) is the Rostock 3D printer, which uses delta kinematics to equate its motion.
