As any one of you are using this parameter to compensate for the shrinkage of the material as it cools down ? If yes, do you have any feedback on how well it works? 


Best regards,

    When I created CNC cutter paths for a mold shop I would scale the model up by the shrink factor before subtracting it from the mold halves.  So shrink was essentially "built in".  I would do the same now for the FDM printer but it hasn't been an issue even for close tolerance details I've printed in PETG or PLA.  If they sit in the sun they expand and if they are in an air conditioned environment they shrink.  

    The setting isn't available for my Creality machine, and although I've thought about it, I haven't found a need for it.  Yet.

    When printing with Polypropylene I have to add 1% shrink factor to get close enought end dimensions. Otherwise I don't use it. I mostly adjust the horizontal expansion to get precise dimensions.
