    Problems to print with Semiflex (Ninjaflex) - HELP!

    Hello everyone!

    I have problems to print items with semi flex. Usually it stopped printing when the item is already 80 or 90 percent done and only once, it worked completely.

    Maybe someone has more knowledge about dealing with that kind of material. I really need help about that, any advice could be helpful in order to get finally successful prints, always and not only sometimes. Like I said in the beginning, after a while it just stops printing, no materials comes anymore. Maybe I have to change sth. about the speed?



    It may be binding up in between your extruder gear and the extruder entry point. With flexible materials this can be an issue. Are you using their recommended temps and print speeds? 210-225C and really slow print speed of 20-30mm/s.

    Edit: Just saw your print speed setting at a max of 80mm/s. You'll probably want to slow that down.


      @AndrewBougie is correct ( We can't give yo any more karma it seems). The recommended SemiFlex Printer settings are:

      Recommended extruder temperature: 210 - 225C
      Recommended platform temperature: 20 - 50C
      Recommended Print Speed: 30 mm/s
      Recommended Extruder: Direct Drive

      Certainly 80mm/s is way to fast.

        Might need a little mod to your extruder. Go to thingiverse and search ninja flex. You'll find a modified extruder frame which basically removes as much the gaps that the material can slip into.

        Also dial down the extrusion rate.


          Forgot to mention. Keep it slow 40-50 mm/s or less.
