Gizmo Dorks PEI Sheet: Ideal 3D Printer Build Surface for Optimal Results

ChristheITguy: Single best upgrade you can get for your 3D printer. Super adhesion with PLA on this thing. It's insane.

Amazon Customer: Use this on my Ender 3 Pro and it's amazing. No slipping during printing and my prints pop right off of the flex steel bed. I used to use BuildTaks and spend forever trying to pry them off the bed, and inevitably nicking the sheet and having to replace it. This holds in place during printing and magically releases without any headache.

It also seems to be lasting a very long time and shows no signs of wear after months of heavy use.

Note the bottom of your prints will have a glassy sheen - I don't mind this and it's an acceptable tradeoff for me.

Amazon Customer: I had been using spring steel pei coated sheets for my bed surface but always had issues leveling my bed. Once I upgraded to a bltouch I was finally able to see why. Small parts were never really an issue but larger parts were. The bed itself was concave and more so the further away from center. Since I already had the glass sheet that shipped with my printer I thought why not try this product. The result was an incredibly flat surface by comparison and unmatched adhesion.

It's easy to apply. All I did was carefully unroll the backing as I pushed air bubbles out along the way after thoroughly cleaning the glass with soap and alcohol . I've never had an issue with air bubbles, deformations, delamination etc. Once applied, I trimmed the remaining with a razor.

The new surface made for some mirror like finishes on parts touching the bed. The only issue was getting the part off of the bed. The best method I've found is to force a razor blade or box knife carefully between the print and the bed. Then, push the blade further under the print until I can fit a metal spatula/scraper under the print. Finally, I move the scraper around until enough of the print becomes free...

Clay Himmelberger: I was having adhesion issues on the stock glass bed (with texture) for the Anycubic Mega SE. I tried IPA, soap and water, saltwater film and at best was losing 1/3 of my prints, maybe more. It was time to try PEI.

Installation was simple. This is like a big sticker, or the protective shield for a cell phone. I removed the glass bed, cleaned with IPA (rubbing alcohol), stuck this sheet on, and let it warm at 60 deg for a while. All this is in the clear instructions. I re-leveled my bed and ...

the first print, and the next 15+ prints (still going) stuck flawlessly. Incredible. Since this was a thin sticker I did not need to change any z-offset values. The same prints that I had loaded (and were failing)

Two things I noticed:
1. the bottom side of all my prints are crazy smooth now. Glass-like.
2. The prints are very hard to remove. Adhesion is through the roof! I found the best way was to slide an exacto knife under the print and then peel, or, knife right into the side the of the print and lift the corner. I hesitate with the scraper (metal) because I don't want to scratch the surface. Pulling hard works sometimes too (just dont't shatter the...

Murray: PLA, TPU, and PETG all stick to this PEI Bed real well. The problem I am having is these filaments stick too well to the PEI surface . I've damaged many of the prints removing them from the PEI surface. On the web others say to coat the PEI surface with a layer of hair spray, Windex window cleaner, or Peanut oil to help reduce the adhesion but the prints were still a fight to get off even then. I do like the nice smooth bottom surface of the 3d print after you get it off. I even left the 3d print on the bed over night and it was still a fight to remove the print from the PEI surface.

"ibelieveinsilence": **** Review edited after communication with seller and using item for about a month and a dozen prints or so. Original review included at end for posterity. ****

I think I screwed up applying the first PEI sheet that I purchased because I did not wait long enough after cleaning the glass plate with IPA before applying the PEI sheet. This caused bubbles once the assembly was heated up to printing temperature, making the print surface uneven and requiring removal of the PEI sheet which was then impossible to reapply and made a big mess.

After reaching out to the seller for advice, they sent me a replacement sheet and were very kind and helpful with giving advice on how best to get it to work for my application and clean up the mess I had made.

Once the second sheet arrived, I followed the included instructions again. This time I gave the IPA ample time to evaporate before applying the PEI sheet to the glass and everything went smoothly. I also waited about a day after applying the sheet before heating it, and then let it sit at 60C for a couple hours before going to 110C to print ABS.

So, how does it print? LIKE A DREAM. Going to this product from the...
