If anyone of you has tried to print elastic materials you will have noticed that you have to reduce extrusion speed quite a lot to keep the filament from getting twisted inside the extruder.
I’m currently thinking on how to improve of this, one idea was to simply cool down the filament to < 0°C. I checked with some precision scales and it seems that at freezer temperatures (roughly -4 °C) the two types of elastic filament i have get a good deal stiffer. I measure by pressing the filament on the scale until it forms a sideways u. One goes from 18g to 27g the other from 10g to 12g.
Has anyone of you tried something similar, if yes with what kind of results?

That would be amazing to do with a peltier/thermoelectric cooler just before the hot end, or a chiller of some sort.
I’m actually aiming at printing elastic material using a bowden extruder
