Thekkiinngg Prusa MK3 /S Double-Sided Textured Pei Powder-Coated Sheet V4

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.

Overall this plate is fine. The texture is slightly deeper than the stock Prusa plate, and definitely much less than the other gold colored aftermarket textured plates. However, the plate is much thinner than the Prusa plate. Normally, this would not be a problem but I have encountered issues with printing ABS and polycarbonate because even though the parts stick very well to the plate, the plate will start to bend up as the part wants to warp. This does not happen on the stock Prusa plate because it is too thick to allow it to bend. But on this plate, it is so thin that the parts that want to warp make the plate warp too.

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.

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 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.
