Another win for the 3D printing community, the guys over at reprap.me have a fully functioning prototype and is now appealing to the community on Kickstarter to help bring their invention into full production. The Diamond Hotend is a single diamond shaped nozzel with 3 chambers allowing you to feed 3 filaments of varying materials at the same time with better precision and color blending. If you have a 3D printer this is a great upgrade but before you go and order one you will need to make sure you get the right mounting brackets, firmware and depending on your printer model you might need additional hardware. The Diamond Hotend requires a motherboard that supports tripple extruders such as the RUMBA motherboard, for detailed installation steps and requirements visit the reprap.org wiki page.
