Found a filament that 3D lac should not be used with

Use hair spray on the glass plate. This is not to help it stick but to assist in removal. I use this on PETG all the time as PETG tends to stick too well to glass plate

printbite ftw

holds awesomely good while hot
releases automagically when cold

The only material it does not work with is TPU, you cannot remove TPU from it at all, it bonds permanently, you can't even scrape it, it messes the printbite surface completely.

You clean with acetone when you touch it but I have it for 2 years without cleaning as you really don't need to touch it ever. Just be patient to let it cool below 30C to release part (or add big fans to cool ti quickly so you don't need to be patient )

I think you would find that hairspray with that particular filament would lead to the same problem that I had with 3DLac (they are essentially the same thing and work they same way). But try it - just don't say I didn't warn you

I tried printbite some years back - didn't work for me - no matter what I did. Couldn't get parts to stick. Given how much it cost me, I was pretty pi**ed off.

@deckingman weird, I have it on 3 printers (would use it everywhere, but, yes, expensive, so the rest of them are glass + whatever glue I can find) .. I just have bed 10C higher than regular temp + I leave it to soak few minutes at that temp before I start print (not sure if it is necessary but I used to use heater on glass before and I had to wait for temp to stabilize on the whole bed so I got that into my process)... 3 important things imho for printing on printbite, you might wanna try it again as I doubt you thrown it away

10C+ bed temp compared to glass+glue so 70C for PLA for e.g. , 85-90C for PETG, 110C for ABS
10-30C+ hotend temp for the first layer
~.1mm higher "Z zero" than with glass as while glass+glue likes to have bead squashed in to, printbite likes the bead to be "laid down" and not squashed into bed, but it likes it bit hotter, that's why .1mm higher Z home offset than with glass

I have them for years, never had a problem, never found a material that won't stick (tpu sticks too good, messes up the printbite)

EDIT: one more thing, never touch it, and never never never clean it with IPA or Ethilen, cleaning with acetone only

@arhi I did throw it away because it was worse than useless for me. Like trying to print on butter or oil.

I know other people swear by it so maybe it was a bad batch or something but I tried everything - higher bed temperature, higher/lower hot end temperature, higher/lower first layer height, micro-stepping to increase/decrease the first layer, bigger nozzle, smaller nozzle and every combination of all of the above.

Of course, I cleaned it with Acetone. I think the best result I had with it was after I attacked it with an orbital sander - that was just before I threw it away in disgust.

@arhi Printbite barely worked for me. It was never consistant on PLA sticking. When I used it, shortly after its release, acetone was not recommened due to it damaging the printbite.

good to hear other experiences, works crazy good for me and the 5 sheets I have (cut for 3 printers) are 4 different versions (purchased in different times) and all work awesome ... good to know it can be ch%$#@^%t too

I use 3Dlac on petg , but with pla I just use a heated bed .

Interesting! I've been using it for several years with both PLA and PETG, and it works very well with both for me.
