I can confirm that petg sticks to buildtak…

Yeah this is why I use their FlexPlate system. I just did a a print for someone in PETG with a 4x8 flat first layer. Took two seconds to remove the print.

try heating it up again to like 50°C…

LOL.
Sorry I probably shouldn’t laugh that looks a pain…

@Rene_Jurack what is your method after heating it up again back to about 50C?

6

hit it fast from the side with the light handle of that chissle… like “kicking” it from the side of the table.

7

sounds weird but works very well. seriously!

Thanks, I’ll try that next :slight_smile:

I searched for a video of it, but I cant find it anymore. It is like this: https://m.youtube.com/watch?v=Viy928RLsdU&feature=youtu.be
but with the “wrong end” of the chisel. Sometimes I give it some ticks from different sides before it comes of. But usually, my prints just pop off, so my method was used only a couple times…

Put the plate and part in freezer. Not so easy is you glued the PEI to the heatbed. This is the main reason why I use borosilicate glas and 3D print spay (=auqanet superstrong hairspray)

@Rene_Jurack ​ i will try the 50 degree trick. But from my experience with abs that makes it harder, but maybe not on petg. The freezer works good on pla, might try that to (if I can fit the 350x350 build platform inside)

yeah, heating it up again is only for the “prying method”. The “kicking method” I described is for a cold bed. Cooling it down with a freezer does help a lot, too.

I’ve printed PETG on Buildtak. Unlike PLA and ABS, you don’t want to squish the PETG onto the bed as much since it will bond very well. If you lift the nozzle from the head, you should be able to get a good stick, without bonding.

On other trick you can try. Get a can of compressed air. This is not really compressed air it is a liquid that evaporates very fast. Often it is propane, believe it or not. So be careful with it.
Heat the part and bed up to 50 or so and while holding the can upside down, blast the print. Liquid will shoot out and evaporate. This will freeze the print, while the bed is still hot. This might just pop it off.

how much itis?
