Double-sided Textured PEI Powder-coated Spring Steel Sheet  

RE: Double-sided Textured PEI Powder-coated Spring Steel Sheet

Just post it for sale on eBay.  

RE: Double-sided Textured PEI Powder-coated Spring Steel Sheet

When I contacted support about the poor adhesion on mine, I spent 45 minutes describing the problem and sending pics. The official line is "it's a consumable" and no warranty is honored, even if it fails straight out of the box. Prusa is denying there's and issue although they have clearly made ninja-edits to the product description and cleaning pages. Some of the sheets are great, but some are clearly turds. Fortunately, there are good 3rd party alternatives that work as advertised.

I have read about this but not experienced it.  I am sure I will.

I hope not! It doesn't affect all sheets, and I'm wondering if there's something in the manufacturing process that affects a small percentage of sheets. Meanwhile, my TheKKIINNGG sheet is amazing. Hoping they produce one sized for the Mini soon.

Mine was somewhat of a turd until I took it to the sink and did the non-recommended soap+water wash. After that it worked like a champ, even for PLA. Must have been some factory residue that IPA just couldn't cut.

I've washed it maybe one additional time since I got it in May; I've also not even bothered with IPA between many prints. (Batch WA-15, FWIW)

The KKIINNGG is good.  I have couple more to test.

I also washed it in the sink with a dishwashing product but nothing better.
Thanks for the Ebay idea but I can't sell a product if it doesn't work, just a matter of respect.

FYI you can't just casually wash it with whatever you have around; there are specifics on the detergent (no skin additives, scents, etc) and you absolutely cannot use e.g. your kitchen sponge or towels. Clean, new dedicated sponge, paper towels, etc. must be used. 

RE: Double-sided Textured PEI Powder-coated Spring Steel Sheet

Of course, thank you but with the sheet found on Ebay I have no problem, so I continue with that.
The idea of my post at the origin was to make me reimburse the sheet of Prusa, since it is not possible it will end up in the trash.
Happy Holidays 🍾
