Result of applying a too strong mix of pva glue to the glass bed
woah…i`m printing on water+pva too and the adhesion is really strong but that strong ? but i mostly use a knife and knock with the sharp side of the blade at the bottom of the printed part until it comes off…did you bend the part off ?
Hi, the part was okay, just left big shells out of the glass. Already diluted down about 20-1, guessing the mix is still to strong lol. But it has solved the warping problem on large parts (150*150 and bigger).
strange…i think my dilution is mostly between 1:5 and 1:10 and it looks much more milky than yours, yours is nearly transparent…i just take some drips water and put 2-3 drips pva in and put it with a brush on the heated bed…but without the knife i think some parts would have broken when trying to get them off…or perhaps the glass
Very nice. I haven’t tried PVA as a topper for ABS prints, but seeing as PVA is water soluble maybe just unclip the glass and dunk it in water next time.
That’s PVA as in PVAlcohol, and not PVAcetate, right?
Using just normal pva glue ( wood glue)
PVA(lcohol) is water soluble. PVA(cetate) is not. At least, according to a quick read of Wikipedia. PVA filament is of the former kind.
As an emulsion in water, aPVAc emulsions are used as adhesives for porous materials, particularly for wood, paper, and cloth, and as a consolidant for porous building stone, in particular sandstone. Uses:
as wood glue PVAc is known as “white glue” and the yellow “carpenter’s glue” or PVA glue.
I think when it
s not dried its water soluble, when it
s dried it isnt.
I think Tony’s using PVA(cetate). But @ThantiK was talking about dunking his plate into water, and I think that requires PVA(lcohol). My understanding is that PVAc is not water soluble.
m using PVAcetate in form of wood glue. From time to time i clean my glasplate under flowing water and with a little bit rubbing its removable. But never tried to remove the parts with water.
Just need to find the right mix of wood glue and water I think
I had the same problem when using nail polish. Switched to kapton tape and the glass doesn’t break anymore.
Good news: cutting glass is super easy.
