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.

  • Paul Franklin | 08/16/2018

    Hi, I have one more question, it says that you can print ABS and other filaments with this, how come the temp rating is 190 to 230 C, I couldnt print ABS with this nozzle at that low temp rating. What is the proper temp range for this nozzle? Wish you would have put out this was coming out, just ordered the older nozzle right before it came off your website, wish you would have contacted me and asked if i wanted updated one.

    • Jocelin Jia | 08/16/2018

      yes,it can up to 230 dgree, it has three heater. ABS PLA is no problem

      • Paul Franklin | 08/16/2018

        Can you change out the nozzle or is it part of the hot end like the last design?

        • Jocelin Jia | 08/17/2018

          the nozzle can change it, it's totally different than previous one.

          • Marco Wintermayr | 12/27/2018

            What kind of nozzle can you switch with? Does it have to be a special one?
