Yes, that is useful for those in the US, but I have no idea where CC resides, so I felt it best not to put up links.

@ ClosedCircuit Why do you require limonene? I thought that it was used to dissolve HIPS support structures? I have a spare sheet of PEI that came with 3M double sided adhesive, for another printer I own ( not applied yet) My Prusa I3 Mk 2 suffered a head crash and scoring in the top right corner of the PEI surface. I have yet to need to print in that area. Rather than replace it I feel I call fill the score, or maybe not.

Re: PEI Sheet damaged - Where do you buy limonene?

Many thanks to all for your help. It's appreciated.

To clarify, I'm based in Switzerland and get hammered by courrier charges and import duties when ordering low value items from abroad, hence why it would be really helpful if I knew which kind(s) of shops sell this stuff. And yes, it is required to remove glue residue when replacing a PEI sheet...

You're not that far away then, and it's much the same here. Limit before tax and duty is charged is €20, but they ask for an invoice on anything less and then the post office charges €7.50 for requesting the invoice.

Limonene also not available here (neither is IPA...). I guess you could try a pharmacy to see if they have any. Another option is to use a razor blade, but please be careful if you do that!

Folowing advice is with no guaranty and if you decide to follow it, do it with maximum caution.

I would try to use tetrachloroethylene. https://en.wikipedia.org/wiki/Tetrachloroethylene It should be available in local drugstore, because it's common detergent. I'm very succesful cleaning adhesive residues with it (especially from stickers). It is also way cheaper then limonene.
But, if you want to try it, first check if tetrachloroethylene doesn't hurt the bed itself. Put a drop on the bed (somewhere in the corner) and check if it is melting or changing colour or dissolving white grid or letters. If it is OK, you can try if it dissolves the adhesive.

Don't forget to take care of your health and safety.

Where are you guys buying the PEI Sheets from?

PRUSA's website has it listed as out of stock.
http://shop.prusa3d.com/en/3d-printer-parts/109-replacement-pei-sheet-ultem.html

I found this on Amazon, but its only 8"x8", and I believe our bed is 8"x10".

Ideally, I would like to support PRUSA, but it would be nice if I could get it in the USA from someone.

Thanks,

You could try looking at a natural supplement type store. Strange stuff.

Re: PEI Sheet damaged - Where do you buy limonene?

Look for it as an "natural orange cleaner/degreaser". Here in the States it can be found as Gojo hand cleaner, "Wipe Away" degreaser, and other citrus/orange cleaners. If you have a store that specializes in natural and organic products, they may have it in the cleaning section. It will rarely be marked as D-Limonene, but the label should mention it. You should also check the label for other less desirable ingredients.

Does anyone know if l-limonene will work? Those products smell like pine, and might be more available in some regions.

Re: PEI Sheet damaged - Where do you buy limonene?

Just use an ordinary glue solvent. Turpentine will work 🙂 Look up Terpene. Strong smelling of resin/aromatic oil.
Yes use turpentine, an ordinary paint solvent it dissolves adhesives readily. The nearest to Limonene.

Below from .... https://en.wikipedia.org/wiki/Limonene

"Limonene is increasingly being used as a solvent for cleaning purposes, such as the removal of oil from machine parts, as it is produced from a renewable source (citrus oil, as a byproduct of orange juice manufacture). It is used as a paint stripper and is also useful as a fragrant alternative to turpentine. Limonene is also used as a solvent in some model airplane glues and as a constituent in some paints. All-natural commercial air fresheners, with air propellants, containing limonene are used by philatelists to remove self-adhesive postage stamps from envelope paper.[13]

Limonene is also finding increased use as a solvent for filament-fused 3D printing.[14] Printers can print the plastic of choice for the model, but erect supports and binders from HIPS, a polystyrene plastic that is easily soluble in limonene."

Thank you all for the great suggestions. Much appreciated!
