The Diamond Nozzle is a brass nozzle for 3D printing in multiple colors and materials. It has three filament inputs for 1.75mm filament and a common 0.4mm nozzle orifice.

The Diamond Nozzle is designed with the smallest possible mixing chamber, to make color shifts as fast as possible and avoid unnecessary filament waste. To ensure rapid nozzle heat up the nozzle have been constructed as compact as possible and features a cutout for standard 40W heater cartridge and leaded thermistor

FAQ

Question: My Diamond Hotend is clogged, how do i clean it?

Answer: Unplug the bowden tubes on the heated Diamond Hotend. Use a heated 2mm hex key to insert in each heatsink, all the way into the nozzle tip and pull out quickly to remove any plastic. Repeat process until clean. No need to disassembly the heatsinks! If nozzle tip is clogged, use a 0.4mm drill/wire to clean from outside.

Question: My Diamond Hotend is leaking, how do i stop the leak?

Answer: After mounting the heatsinks, heatup the nozzle to 240-250 degree celcius and tighten the heatsink with a plier. If still leaking you can use some PFTE tape on the heatsink threads. Never use cooling paste on the threads!
