Thekkiinngg Prusa I3 MK3 MK52 Black Double Sided Textured PEI Spring Steel Sheet Powder Coated PEI Build Plate for Prusa i3/Ａquila pro/CR6 SE MK2.5S MK3 MK3S, 253.8 x 241MM

Thekkiinngg's version of the PRUSA Mk3 flexible steel textured PEI coated print bed surface is as good as I've heard and is my best print surface to date. The original Prusa textured steel PEI surface is difficult to get adhesion with while this version works well, at least with PETG which is my usual material. Even long narrow prints stick just well enough to avoid warping, shifting or popping off prematurely but pop off quite easily after the bed cools down.... exactly as Prusa's textured sheets were supposed to do and sometimes actually do. Finding a good surface for PETG was tricky for me. On everything else I've tried PETG either sticks far too well or not at all. Thekkiinngg seems to have gotten it exactly right with this textured sheet. The textured finish left on the parts is good, and even a print that was the entire width the bed, only 50mm deep and 100mm tall stayed stuck and did not warp. A definite must have for Prusa Mk2.5 and Mk3 users! Use it alongside the Prusa sheets and you should have something that works for most occasions.

I have used this for about 180+ hours of printing so far and it works flawlessly. I printed all the parts for my Prusa Box and they came out perfect without a singe failed print due to layer adhesion. I wish I could say that for the Original Prusa build plates that came with my machine. I tend to always have issues with those. Not a single problem with first layer adhesion on this new plate. No glue or hairspray, or other sticky gunk needed. So far this is the best build plate I have used in recent months. I have tried a number of other brands and some are too textured, some the surface came off when I removed the prints and others were just as bad as the Prusa ones. Another thing I really like is that this one’s texture is very close to the same texture as the Original Prusa plate. It’s textured but not like the surface of the moon like others I’ve tried, well that’s and exaggeration, but if you have some of those other textured plates you know what I mean. I highly recommend this plate.

I've been wanting to get a textured PEI plate for my Prusa I3Mk3 for a while. Well, I pulled the trigger on this and so-far have not been sorry. After using the smooth Prusa build sheet from day one, I've gotten used to prints occasionally popping off mid-print. So far that hasn't happened with this sheet. I had all but given up with PETG and ABS, but I'm looking forward to trying those on this sheet as well. If it works anywhere as well as PLA has so far I'll be extremely happy. Now, to address the thinness of the build plate. Yes this plate appears to be about half the thickness of my original build plate. Yes you do have to set up a new build plate profile, but you would have to do that with any new build plate. I simply ran a first layer calibration and within minutes was getting a perfect first layer. With that said, there has been no problem with it magnetically sticking to the printer bed. So far, I haven't had to remove the build plate to remove my prints. I simply wait for the bed to cool to room temperature and the parts almost lift right off without flexing. This may change with other filament types, but so far this has been the case for me. If anything I would think that the thinner sheet would allow parts to come off easier when flexing is required. Time will tell. Based on the success I've already had with this plate, I just ordered a second plate as a back-up. I'm hoping the next one works equally as well as this one has so far.

This sheet does work with the Prusa Mk3, a few things i found compared to the smooth plate that you can get from Prusa. 1. This sheet is thinner, by about 1/2. Means much lower Z offset for this sheet. Also leads to it being more bendy, when trying to pull it off the bed will tend to tilt the printer back as it does not come off the magnets as easily. Could also be an issue if you bend it to much you put a crease in it that would ruin it. 2. Texture works as advertised, and the non-stick Pei works well at releasing when printing with PETG, the parts are stuck on good during printing, and then after cooling they pretty much come off on their own. 3. Sheet covers bed correctly and is double sided to give more options if one side is damaged. Will need to see how it holds up in the long run, but after at least 5 or 6 hours of prints it has no issues, with temps up to 90c for PETG

Update-I’ve had this sheet for 8 months now and it still gets five stars. It has worked perfectly with every filament I’ve tried regardless of brand or type—PLA, PETG, ABS, ASA, and TPU worked and stuck perfectly. PETG sticks a little well so I just spray some windex on it and let it sit and then the parts come off perfectly. I have printed hundreds of parts on this sheet and it still looks brand new. Every few prints I spray some 98% IPA on and wipe it off. Five stars for sure. Original review: I’ve had this for about five months and printed lots of brands of filament on it. This works extremely well for PLA and PETG. I rarely even take it off of the bed to bend it to get the parts off. Most of the time they just pop right off, especially PLA. The handful of times I’ve had adhesion issues, a quick spritz of 90% isopropyl alcohol and it’s perfect again. It also leaves a really neat impression on the bottom of the parts. PETG adheres *almost* too well and will come off with bending the sheet or scraping with a PETG printed scraper. The prime line is pretty difficult to get off with PETG though and I usually have to use my fingernail. I have not tried TPU or any more exotic filaments yet. 5/5 stars, great buy.

I realized after I ordered my Mk3s+ with a smooth sheet that the PETG I was mostly wanting to print the first few weeks was better done on a textured sheet, and that additional factory sheets would take weeks to arrive. A quick look, and this was on my porch quickly. It works great for PETG, and even works OK for larger PLA parts, and some ABS when warping is not too likely. Though smaller footprint PLA and trickier ABS are better done on the smooth sheet. But for PETG, this has been so good that I haven’t moved to the factory textured sheet even after it arrived. As others have said, it is thinner, and you definitely need to set it up with its own profile and live Z calibration. But being thinner makes it easier to flex to remove parts. In fact, sometimes they separate just lifting the sheet off the printer. So one month in, roughly 12 hours a day of use, nearly all on this sheet, and so far, it looks and behaves like new.

I own a couple Original Prusa MK3S printers but only have one of their textured sheets. Original Prusa textured sheets are rarely available in their store, and shipping is expensive. Having only one sheet became an issue when I started printing a product that was enhanced by the textured look. I purchased a gold textured sheet and was impressed with it's adhesion. Unfortunately it has a much deeper texture which doesn't look as good. This sheet has great adhesion and texture that is more like the Original Prusa sheet. One reviewer commented that this sheet was thin and buckled under prints with materials that warp. That isn't a concern for me since I am printing PETG. The thinner sheet makes it easier to pop prints off the sheet. I may actually prefer it over the original, time will tell...

This sheet has worked fine. It is much thinner than the original. This means it flexes more. Good for removing parts. Annoying when putting in on the bed. Adhesion is good. I don't use any thing but a clean sheet for PLA. The texture is ok, but I prefer the Prusa texture more. This one looks like it was sprayed on too thick. The low spots are good, but the high spots are too thick. It gives the appearance like someone melted the surface. Another way to describe it would be there are more high spots than low spots, and they run together. This give the print the opposite effect. The low spots on the prints look shinny because they reduce the randomness.
