Pure Curiosity: Any Slicer supporting 7 Extruders/Hotends?



  • Hey there!

    As you all may know, the Duetwifi supports (With the help of the Duex5) 7 Extruders. But is any Slicer supporting that many Extruders and therefore Hotend?

    Slic3r does. In fact I'm not sure what the limit is, if any. On the Duet, they are referred to as tools but Slic3r refers to them as extruders. I use a Diamond hot end with 3 inputs but it's a mixing hot end so you can define tools using any combination of the 3 extruders in various percentages. As far as Slic3r is concerned, it considers each tool to be a separate extruder (which in fact it could be). I usually define 4 tools, one for each extruder plus a 4th to use all 3, then vary the mixing ratio for the 4th tool by post processing the gcode file. I did once print a "painting" which had 7 colours on the same layer so 7 tools (extruders as far a Slic3r is concerned) then made a 7 part stl file with each part representing a different colour. In Slic3r, you upload each part then assign whatever tool (extruder) you want to that part. There is a small "bug" in Slicr3r which may cause some people to think that the limit is 4 extruders. That's because when you assign an extruder to a part, the drop down list only has numbers 1 to 4 but you can type any number you like into the box and are not limited to 4. HTH

  • I feel lie this has been discussed before, but can't you achieve full RGB color with 5 extruders? I guess 6 and 7 could be used for support 😄

    In theory you can, but in reality nobody has yet made a commercially available true mixing hot end. With multiple filaments going into a single nozzle, like the Diamond, what comes out is akin to stripey toothpaste. To save me typing, I did a bit of a write up of this on my blog https://somei3deas.wordpress.com/2017/01/28/the-stripey-toothpaste-effect-of-the-diamond-hot-end/



  • OK, thanks guys 🙂
