I had persistent issues with prints "welding" to the stock BuildTak build surface on my Raise3D Pro 2. I went through quite a few in just a few months, generally after ripping the surface with a scraper in a desperate effort to get a print off. I tried so many things from printer leveling, to exhaustive tweaking of filament settings. Frustrated, I decided to give the Gizmo Dorks PEI Sheet a go. Wow - what a difference. It's like magic: firm hold on prints during printing, and then magic release once the bed cools down. And the quality of layer 1 is stunning - it's glossy with no evidence of lines - doesn't even look like the product of a 3D printer!

El acabado que deja en la primera capa es super bueno

I'm a big fan of PEI sheets for 3D printers, they just work. Gizmodorks makes good ones too (I have them on 2 printers). PEI works best for PLA, but also works for PETG, and I have used them with ABS (not this one however). PLA requires nothing, just print normally and the print will stick and pop off when it cools. For PETG, I find that it can stick a bit too well (I use 60°C), but it is usually not a problem unless there is a large surface area that will stick to the bed, and then I hit it with some hairspray as a release agent. One of the benefits of a thick PEI sheet like this, is that you can easily hit it with scotch brite or sandpaper to clean it up, but that does have the downside of dulling the shiny finish. I prefer a bit of a matte finish though anyway. One tip though - when you install these, if your printer has rounded corners, I'd recommend rounding the corners on the PEI sheet as well, since they are sharp and bumping into one can have negative consequences for your knuckles (or so I have heard).

I've been using a CR-10S for a while now and always used the stock glass bed that came with it. I would just go apply some childrens glue to the bed before doing a print to get good bed adhesion. But I was getting rather annoyed with this process. I have my printer set up to be controlled by octoprint and monitored through a webcam, so it was extremely annoying to have to go in there every time and apply glue after the bed and hot end is already heated before I could remotely send and start a print. If I applied the glue before heating the glue would dry by the time everything heated up and not give good adhesion.This PEI sheet has solved my problems amazingly. No bed prep whatsoever and so far 10 prints have stuck perfectly. And after a print when the bed cools removing the print is very easy. I don't even need to use any tools like I did with the glass and glue method. Plus the glue method would sometimes leave a very messy looking finish, with the PEI it's a nice glossy finish every time.If this product holds up it will probably be one of the best upgrades I've ever done on my 3d printer. It's cheap enough also that replacing it occasionally shouldn't be that big of a deal, but I'm a little worried about how hard the old sheet will be to get off if that time comes lol.

I've been "suffering" bed adhesion a lot lately, to put blatantly simple. Truth be told, I saw this coming, it's common for men my age to experience issues in the bed but after doing a lot of research online and through the elimination of other supplements I came to this product, and thought "Hey its twenty dollars, its worth a shot I guess". Wham, bam, shang a lang, and a little bit of sha-la-la-la-la later and this arrives at my front door, packed well and all. Needless to say, my excitement was rising in more ways than one.Up the stairs I go, my face brim-full with childish glee as I eagerly unwrap the present delivered to me by the amazon god in the sky, and I race to take off my current print surface as fast as I can. I set up my slicer for the proper heat settings for this bed (70c) and get a nice little torture test ready to print, to see if this bed experience will meet up to my unreasonably high expectations.As soon as I started the print, my hopes and dreams were shattered faster than a highly infective virus can spread. I stared in total disappointment as I saw the melted plastic sticking to everything on my printer except for the bed, where it should be sticking but I've been let down before in life, I won't let a silly little printer bed beat me harder than every grade school teacher in my life.One ant-man later as I was pondering at what point in my life did I go wrong, and I look over at the bed, it staring at me with its laughing gaze, as if it was taunting me and all my failures in life. I take another look at the surface and get mad because it isn't even clear as pei should be, yet it had a slightly blue tinge to it. "What's one more problem to add to this terrible product," I think to myself as I whip out my phone to leave a disparaging review on this product, and in a fit of my rage I take my anger out on the bed surface. I scratch it with my fingernails and to my surprise, a sort of film-like material scrapes off with my abhorrently long quarantine nails, and then, like a wrong way truck going 80, it hits me. I forgot to take off the protective film.Anyways after a few prints later this product amazes me with how well it can hold on to molten plastic that has never liked to stick to anything on my printer in while, if you cant get your print to stick this works well. I've seen some people say to sand it but I haven't needed to, and I've been printing objects with more islands (small surfaces on the object that don't stick to beds well) than the Philippines and it prints amazingly. I'll leave below some handy temperatures to help if you'd like them.Pla: 70-75 degreesAbs: 105-110 degreesNylon: who in their right mind prints nylon on this printer, it's such a terrible idea, dear god don't do it.I did take a star off what would've been a perfect five-star review because in the fit of rage I had earlier, my wife left and took the kids with her and I haven't heard from her since, but ill update when that situation changes. Also because it's really easy to get air bubbles in the adhesive when you apply it to your printer so be careful on that part too.
