Diamond Hotend makes multi-color 3D printing possible from a single nozzle
Entrepreneurs in Denmark have taken another step towards improving the general usability of 3D printers with the Diamond Hotend, a single 3D extruder unit that can mix and melt three filaments together and produce items in a rainbow of colors.
“Hot end” refers to 3D printers which work by melting a plastic filament with a heater element, such as the FDM technology. The “hot end” extrudes the melted plastic out of a small nozzle, one material and color at a time. The Diamond Hotend by RepRap.me combines three heating chambers with a single nozzle to create a new sort of 3D hot end that can extrude different colors.
