different temperatures for outer walls and for the infill with the same filament (vario shore tpu)
Hello I hope someone can help me with the following,
Is it possible with settings in prusa slicer you can use different temperatures for outer walls and for the infill i want to do a test with varioshore tpu so the outside is firm and the inside more flexible the great thing about this filemant is that the temperature with which you print regulates the softness. I've searched but didn't find anything, maybe I didn't search properly but I hope someone has an answer, thanks in advance

Hello, rhaye.
I don't have the answers, but perhaps you may find my personal experience to be helpful in your pursuit.
I have not used the vario filament, but I have printed my own alloy filaments, such as carbon nylon/tpu, glass alloy nylon/carbon nylon/alloy 910 nylon, and others. (I then loaded the coil of custom filament I just printed, back into the printer, to print the intended object.) Printing/creating these custom filaments required me to set filament changes in Prusaslicer. I did this by right clicking the layer slider at the layer where I wanted to change filaments. In your case, I think you should be able to enter the GCODE for nozzle temp change, and skip the whole change filament routine of unload/load/purge. I have not persoanlly done this, so you will need to research the documentation for the specific details, or wait for someone more knowledgeable to come along.
I understand the method I present makes changes at the layer, which leaves your vision for perimeter/infill nozzle temp variation yet to be solved, but I do hope this information helps to get you moving in the right direction for customizing your GCODE, through the Prusaslicer interface.
Regards-

thank you for your response, to be honest I don't quite understand your answer.I understand your gcode story that you use for example a temp. Tower.maybe I didn't explain it well. Suppose I make a cube then I want the outside at 115 degrees and the infill at 220, this gives a soft inside.
Do I understand correctly that you can indicate in the gcode if the printer is going to do infill? I can choose a different temp for the infill?if so, do you have the code for this? that are so nice. I must be stupid because I haven't been able to find it yet.
thank you very much in advance

Slice a simple cube and check the output gcode. The different types of extrusion are labelled in the gcode file. PRUSA slicer recent versions has a post processing function, you could use these keywords to post process the file and add in temperature change commands. So yes, technically it is possible to do. print settings>Output options iirc, not at my pc at the moment to check the exact location.
The problem you will have is that temperature changes don’t happen that quickly so when it changes from infill at 220 for example to your lower temps for perimeters that it’s going to take time for the extruder to cool down. So depending on the size of the islands you might not see any actual drop before it goes back to printing infill and heats up again.

Thanks for the idea I'll just give it a try and see how far I get.Yes, I am aware of the cooling and heating problem that will be quite a challenge and I am also curious what this will do to the end result. Fortunately I don't need it for a proect now but who knows what will come my way.thanks and regards
