I'm having trouble printing with Ultimaker's PVA support material. It wíll not stick to the PLA filamant when printing with support. It's being pulled off, jamming the print job - nomatter printing incl. tower og not. Wrong support material? Temperature adjustment?

Suggestions?

    Hi there,

    Welcome to the forums! :)

    PLA sticks to PVA (once you get your settings right), but PVA does not stick to PLA. See the difference? PVA does not like to be on top. ;)

    So, if you have a model where you need PVA to go over top of some PLA, then the current answer is to use the Horizontal Expansion option under Support (assuming Cura 2.3+) and expand the supports out so that all support parts are connected to the build plate. I've used 3-5mm so far, depending on the model.

    It seems wasteful of the PVA, but currently that is what it takes to make PVA over PLA work. ... At least as I understand things. I am still learning PVA myself.

    Anyway, hope this helps. Good luck! :)

    Yes ! Sometimes if you need support inside the part, horizontal expansion does not work, and it's impossible to do print PVA on top of PLA.

    I have tried with many fails. I have removed PVA supports inside the part (supports from build plate only).
