Features

  • Made in the USA - Ultem 1000 PEI sheet installs quickly via the laminated adhesive on top of existing flat build platforms (e.g. borosilicate glass)
  • Bubble free application - The 3M 468MP adhesive is already preapplied to the PEI; simply peel back the tape liner for quick adhesion to the bed
  • Build Surface - PEI is the perfect no prep build surface which is endlessly reusable for multiple prints; clean with isopropypl alcohol between prints (or with acetone on a COLD bed)
  • ABS and PLA filaments (along with many other materials) print directly on to PEI surface without the need for additional adhesives, tapes, or slurry
  • Dimensions: 235 x 235mm / PEI thickness: 0.56mm (0.022 inches) / Laminated 3M 468MP adhesive thickness: 0.13mm (0.005 inches) / Fits the Creality Ender 3 or Creality CR 20 perfectly!

Description

InstallationThe polyetherimide sheet comes with 3M 468MP adhesive already laminated to the PEI. Apply the PEI with slight pressure and at an angle to prevent and minimize air bubbles. Once applied set the print bed to 60C and apply pressure evenly across the PEI in a sweeping fashion to firmly set the adhesive. Please use a towel to avoid getting burned. Level the bed and set the height of the nozzle before printing.If PEI is installed to the top surface of a bed sandwich (a build plate with multiple layers), it is recommended to install PEI on top of borosilicate glass.UseHeat the bed to the desired temperatures for printing (60 C for PLA and 100 C for ABS). Depending on how thick your bed sandwich is, your set temperature may not be your surface PEI temperature.When the print is completed, let the bed cool, and the part will be easy to release from the PEI surface. Parts are easier to remove if released before the bed becomes completely cold.Leveling the bed is very, very important when using PEI. You want the first layer to be close enough to be squished a little. PETG is an exception and doesn't like squished layers, in which case a Z gap should be used.MaintenanceClean in between prints with isopropyl alcohol. Acetone can be used instead of isopropyl alcohol, but the bed must be cold if acetone is used. Optionally, light sanding with 600-1000 grit sand paper can be done after lots of printing to give the PEI sheet more life.CompatibilityCreality Ender 3 / Creality CR 20 / and more!The Creality Ender 3 and the CR 20 have build volumes of 220 x 220mm with a plate size of 235 x 235mm.Dimensions235mm x 235mm (9.25 x 9.25 inches) PEI thickness: 0.56mm (0.022 inches) 3M 468MP adhesive thickness: 0.13mm (0.005 inches)

    • I wouldn’t use it on glass
It’s honestly amazing how well things stick to this. It’s like glue. Your bed leveling can be way off, and your print will still stick like crazy. It’s ridiculous and way more sticky than a PEI coated steel bed. Where I went wrong was that I followed the instructions and put it on top of glass. The problem with this is that it sticks so well nothing will ever come off of it. The freezer method doesn’t work either. I’ve had many frustrating prints that would just not separate from the bed. I haven’t tried this on a steel sheet or any other form of bendable build plate, but I’d imagine that would be a good combination. ... show more

    • If installed correctly, it’s gets no better
Review Image by Mike T
I wasted a couple of these trying to get it right then instructions say to install it from the corner and then along the way and then to put it on a 60°C bed to work the bubbles out. I disagree with us as the bubbles will continue to be created from the gases released in the adhesion when your bed reaches high temperatures, what I have found is to first heat your glass to 70 Celsius, and also heat the PEI on top of the glass without taking off the adhesive covering first. Meanwhile I use a heated cutting board which is made out of bamboo and I hate it inside of my oven to about 300° and I then take my Boro glass and lay it on top of The heated cutting board and remove the protective covering and start working from the corner along to the end with a rag in my hand so that it can work all the bubbles out. This is work very well and I have now four of these that look amazing and have zero wave or lift and I’m very pleased with them. ... show more

    • Amazing adhesion, almost too good. I'm firmly in the PEI camp now.
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 glass!) So that is a slight downside but negligible when compared to the hassles of a print not even starting! (or coming loose mid way through). Printer is running again full time. I've very pleased and will order this again if I need to. ... show more

    • Life changing product
**** 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 original Elder 3 Pro magnetic surface is like night and day. First up, this over a glass sheet is completely flat! I was finally able to truly get my bed level. And best of all, I haven't had to re-level the bed in over a dozen prints. I prepped the surface with 800 grit sandpaper (didn't have the 600 that is recommended on hand) - just doing light circular scuffs over the print surface. This makes prints stick evenly and well. I've really had to try to get adhesion failure (printing a circle on it's side is still not going to work). Best of all, prints pop off cleanly once the surface cools down. Even large prints with a lot of adhered area (4"x4" for instance) pop off cleanly. I have not had any lifting up at the edges or any sagging like I used to have with ABS on the oem Ender 3 Pro surface. Cleanup is equally a breeze. Unlike the oem Ender 3 Pro surface the 3D print material does not get stuck into the rough surface. After a dozen prints the surface still looks and performs as well as on the first print. All I do for cleanup is wiping the surface down with some household IPA prior to printing. By the time the bed gets up to temp (I print at 110C) the IPA is evaporated and the print sticks nicely. Best of all, if the print surface starts having issues I will be able to renew it bu scuffing up with sandpaper again. The PEI sheet is about 1mm thick, so it will last a long time yet! **** Original review starts below. Lessons learned are not to rush and to let the IPA fully evaporate before applying the PEI sheet. **** Looks like a nice product, made in the USA. No idea how well it prints yet, since I didn't get that far. Applied to a sheet of glass (also from Amazon). Cleaned glass beforehand with IPA, (instruction sticker says to use IPA to clean the PEI sheet so figured it would be safe). Adhesive is very tacky, but I was able to get it attached to the glass on the first try with no bubbles at all (use the rolling method, like the description recommends). All was good, no bubbles at 60C per installation instructions. Went to print ABS, and got it to 110C and noticed BIG bubbles forming right in the center of the sheet, wasn't able to get them out without peeling up the edge, which ruined the adhesive throughout (torn / clumped up adhesive so the sheet wouldn't stick flat anymore). Now I've got a PEI sheet and a glass plate both covered in bits of very tacky adhesive. Not good. Going to try cleaning it off then maybe sticking it down with something else, but don't know what would stand up to the ABS printing temperatures. Will probably just have to return it... :/ ... show more

    • Spectacular print adhesion
I've been using these PEI sheets for a couple years on a couple of my printers. they're high quality and have great adhesion. Pro-tip: a quick wipe-down with rubbing alcohol prior to each print (higher percentage is better) will clean any dust or oils off of the plate.
