Change Material during Printing and use 3rd Material

If I have a support material and print it together with PLA, later on the support material is not needed any longer. Is it possible to change the support material to TPU and print TPU together with PLA? If yes, what would be the workflow for that?

I don't recommend you to use TPU as support material, it's very flexible and you can lose the print if the support bents.

 

For the supports exists a lot of solutions, for example, the PVA that is soluble in water. To use a different material for the supports, go to the support option and change the support extruder to the extruder that has the other material.

I don't want to use TPU as support material. Say we use PVA as support material together with PLA. On the same print PVA is not needed anymore after a certain moment. So on the extruder that uses PVA we want to change the material to TPU and print PLA together with TPU.

Is it now clear what is the question?

I think that question was clear.  Did you ever find a solution?   One possible solution would be to just cut your filament and let the printer filament detect catch that it’s out of filament.  Load the new filament and resume.  Then you likely would need to change the temperature settings for the new material. Do that manually in the touch screen interface. 

might work, just a thought. Good luck.

Hello Peter, yes that might work. Well I haven't tried Multimaterial anymore because there were problems with the silicon wipes that were pushed out after a few wipes so you have to check the wipes all the time and push it back. No good experience. In the meantime I replaced the holder of the silicon wipes to prevent the push out but haven't tried multimaterial since then. What I like is the Duplication and Mirror Mode that is a good save of time 🙂

Yep use TPU as a support material is not a good idea instead use PVA its a candy that you will enjoy every day 🤣

Late to the game here but the question is about using the second extruder with a third material once the height has been reached where soluble support is no longer needed. 

This being an unusual use case it would involve a work around- slice the mode once with supports, slice again without supports, but with the third material set as the second extruder material. Save both as gcode on the computer. Figure out the layer you want to change filament and role of the second extruder. Then manually edit the gcodes together. I use Repetier Host to edit gcode, but it is possible to use a text editor. If the latter the key is to find the Z lift command at the layer you want to change at (make sure it isn’t a z hop movement), then cut the soluble support gcode after that. Add in a pause routine to change the filament.  Then paste in the third material gcode (the part after the layer with your change)  after that. I would check the combined gcode in a previewer, like Repetier to make sure it looks right visually.
