Ultimaker Advanced Print Kits - Adhesive Sheets are TOO GOOD?

Recommended Posts

Posted · Ultimaker Advanced Print Kits - Adhesive Sheets are TOO GOOD?

Got my kit yesterday, slapped on an adhesive sheet and started a print (100mm x 100mm print)

Now I can't get the PLA print off the plate without destroying the adhesive sheet. Its stuck so good I'm worried about breaking the glass plate during removal.

Does anybody have any experience with these, or perhaps a tip or trick I don't know yet?

My next attempt involves modifying a paint scraper, so any advice would be greatly appreciated.

I would not use the adhesion sheet for something like PLA for a variety of reasons, but mostly because there are cheaper alternatives for that type of material.

I believe they were for materials like ABS, PC and things that tend to warp a bit off the plate.

But, that is a guess on my part as I have not gotten around to testing that out yet.

Fair point.

But I am still stuck with a print solidly adhered to a plate, and I would rather get the print off without destroying the sheet. This is my current dilemma.

I had the idea of putting the glass plate back in the Ulti3 and cranking up the heat until it seperates. The adhesion sheets can happily go up to 100'c.

That is a thought. On the surface it sounds logical and should be tried. I would. But, that is me...LOL...

I am waiting to try it on a part that I print in something like PC or PP. I usually do not have much warping issues with other materials, but I do know that PC can warp under certain conditions and geometries.

There is a big thread about the sheets and other things about the advanced printing kits, but the sheets are a main topic. You can find it here.

I don't know about the adhesion sheets but when I can't get prints off the bed, I let the glass plate cool in the freezer for half an hour and then the prints come off.

Might work with the adhesion sheets too.

Unfortunately the freezer trick doesn't work with the sheets, at least not with PC. But afaik @neotko knows a trick with window cleaner?

I can second the advice to not use an adhesion sheet for PLA. Curious to know if heating it up will make the PLA soft and if you'll be able to get it off then. Sometimes people also put their buildplate in a freezer, but that is usually to save time on the cooling down process. I assume yours has cooled down by now.

I think the idea with the freezer is to have the part minimally shrink and thus break the bond with the glass plate. Too bad it doesn't work with the adhesion sheet.

I think the hint from Neo was to add few drops of water on the outer perimeter of your print - right where the edge of the model comes into contact with the adhesion sheet. The plan is to make use of the capillary action (when water tries to fill every little space between the sheet and the model) and break the adhesion.

Exactly like @nicolinux said. It works with pla/flexibles/greentec you can remove even using strong adhesion Hair Spray. I do that every day to speed up & I can avoid removing the plate to keep the bed level intact

Ok, so I tried capillary action with water, alcohol and even window cleaner to no avail.

Ended up heating the bed to 65/70'c and pushed a plastic paint scraper under the print.

Only minimal warping after it had cooled (: but the adhesion sheet was destroyed.

Honestly my big issue with this, is that my supplier put me onto these adhesion sheets when I asked him for PEI sheets, which Australia apparently cannot get their collective hands on.

I will hang onto the adhesion sheets for CPE and other tempermental materials

Well the window washer trick was for Glass. With a sheet indeed most probably won’t work.

Happy to hear you managed to get your print off, but I'm sorry that your first experience with the adhesion sheets was with PLA and it got so stuck. Well, at least we know that they work ;)
