What materials will PVA support work with?

I'd love to know if it will work with Colorfabb nGen...someone said no, but didn't elaborate.

Is it only PLA? :shock:

We only were supposed to use it with PLA and with Nylon during the beta testing at least, not with ABS or CPE.

Ugh....see PLA is fine for most stuff but for prints that require more heat resistance (nGen and other materials)...it would be a huge convenience if the dissolvable support material worked for them.

.. and it also dont work with the Colorfabb PLA/PHA which usually prints awsome.. :-(

I wonder why it doesn't work with the ColorFabb PLA/PHA, in that case it's likely not to work with other PLAs either.
They are in the printrange of 180-210. So I wonder what the problem is heat or material bonding?

Maybe Colorfabb will make their own PVA material to work with their stuff?

I'd love a UM3 but if it can't do much with anything other than PLA for support...and I don't have much use for dual material prints...!!

What about the Prusa i3 with dual printheads?

Well they have multiple extruders....

The reason is - as far as I understood - that it is a mixture with PHA and therefore not "sticky" enought to make sure that the PVA sticks to it when printing support on top of a existing structure...

E3d Scaffold seems to work with a wider range of material, in particular with their Edge PET...

Yea also for prints that have supports accessible polymax support seems to work with most of the stuff too. But it doesn't dissolve. Foehnsturm used it on a number of prints on his um2+ magnetic changer.

The main issue with pva is that it doesn't really stick on top of anything. So basically if the pva structure muust start over normal pla, it becomes quite complex to have a perfect print.

The e3d support material seems quite promising. Is a matter or time for new materials to show up now that there's a printer that can actually print them over and over.

You mean Polymaker Polysupport, not Polymax, right? (polymax is their impact modified PLA)

Yeah that one. Need more coffee...

I have a roll of PVA and a roll of PolySupport in my stock since a few month - brand new, never used... had not the need to do so.
Stupid question out of this: is it really something worth to try/use...? What´s your impression?

Coffee... good hint...
