This 3 in 1 out hotend kit is upgraded to enhance the printing performance of Kossel or Rostock 3D printers. 

The hotend is re-designed to reduce the rate of clogging or jamming. We have designed the nozzle to have smallest possible mixing chamber to make color shifts as fast as possible and to avoid unnecessary filament waste. Besides, to ensure rapid nozzle heat up, 3 heater rods of the same power are adopted to guarantee uniform heating of the mixed filament.

Based on the principle of the three primary colors, the three kind of different colored filament will be fed in accordance with a certain percentage of feeding rate. Then they will be melted and mixed in the nozzle chamber to generate another new color or mixed color, enrich your printing life.

If you want to use it on other printer, you will need to make modifications according to your project. Welcomed to share your fantastic idea with us in our forum. 

Main features:

1. 3 in 1 out hotend supports 3 filaments of different colors and different materials.

2. Creating printings with a wide range of colors and materials in a single object, in one print.

3. All-metal, high performance J-head with efficient heat dissipation for fantastic printing.

6. All-metal accessories to withstand higher temperatures involved in printing process so that you can print with multiple kinds of filament that requires higher temperature such as ABS of higher strength.

Tips: Different materials of filament has different melting point, when printing with two different kinds of material, please choose those with close melting point.
