Posted · Polypropylene and PVA?

It looks like it's not supported with PVA according to the latest table on the compatibility chart: https://ultimaker.com/en/resources/49799-material-compatibility

PVA only seems to be supported with CPE, PLA, and Nylon. It says TPU, PC, and ABS are considered experimental/use at your own risk, but my impression has always been that PC and ABS do not adhere well to PVA.

    Polypropylene is very chemically resistant because it doesn't interact with most other materials. This is a nice property but also has some downsides:

    - It doesn't stick to other polymers (so no PVA)

    - It's hard to stick PP to glass, with small prints it's possible but bigger prints need adhesion stickers

    From some practical tests I can say that PP does not stick on PVA as @Tomhe wrote. So forget this combination for large horizontal overhangs or 'islands'. However, I managed to print a small object with PP and PVA support which had well connected PP layers and just needed the PVA as a bed so no PP line hangs on the bottom side.

    Thanks for the info everybody! I didn't want to waste PP on supports, but I guess I have to now.
