I accidentally purchased this not realizing it was a 350 x 350 printer bed but the funniest thing in the world is that it actually fits the t300 perfectly. Since the bed is raised a tiny bit it lines up with it spot on and all you have to do is slide it over to the right a tiny bit and it perfectly fits fine in place and moves back and forth with no problems. Not bad.

Bought the 350mm size, package says 350mm but when I put it on my Ender 5 plus it was too small for the 350mm print bed. Now I have to return this and wait several more days for a different brand PEI sheet to get delivered. What a waste of time and resources.

This is my first time using this style of build plate, and I'm super impressed! Prints stick great when it's hot, and pop right off when it's cool! However, it's a little too long in the Y axis for a CR10S, so it hangs off of front edge of the aluminum heatbed a little bit. It doesn't affect the function at all, but still something to be aware of.

El material de la cama parece bastante solido y de buena calidad, ya he impreso algunas cosas y no hay problemas de adhesión en el PLA. Pense que el pegamiento de la placa magnetica que va a la impresora acabaria derritiendo debido al calor, pero hasta el momento no ha habido problemas. Muy buena opción si buscas cambiar la cama de impresión de fabrica de tu impresora, ademas tiene de diferentes tamaños yo compre la de 210 x 210 mm.

It is imperative to have proper bed adhesion when 3D printing. PLA is pretty easy to work with. But if you use any other filament material besides PLA, you’ll need something other than whatever stock print bed comes with your printer.I’ve switched to printing exclusively ABS over the past two years, and this print bed is a must. I was using glass with an ABS slurry to get good adhesion, but it’s messy and a pain to setup for every print. But with the PEI print bed, the ABS prints stay. When the bed is heated and the print is going, the print sticks really well. When the bed cools, the print pops right off with minimal effort.This has to do with its thermal properties that cause the PEI to expand a little when heated, providing a good surface to stick to. And then it contracts as it cools, aiding in the release of the print.This bed is also double-sided, so if you damage the surface of one side as I did, (because I forgot to level the bed after a failed print and nozzle swap), you can just flip it over. I’ve left it facing up, because despite the bed having a small gouge in one area, it still works fine, even on that spot.This specific PEI print bed has been great. And if I knew how great it was when I switched to ABS, I wouldn’t have wasted my time with the glass and ABS slurry.

Queda muy bien en la plancha de la impresora, se desprende fácilmente el producto impreso.

Great build plate. Print sticks well while printing and comes off easily when the plate cools off .

I'm new to 3D printing. I have a Longer LK5 Pro, which is the only 3D printer I've ever used. That printer seems to work very well, but with as little experience as I have, what do I know? The one thing I've struggled with so far is getting my prints off of the glass bed once they're done. I'd read about all sorts of problems people have getting their prints to stick to the print bed. I had the opposite problem...prints stuck to the bed so firmly that I struggled getting them loose. On prints where there was wide contact area...like a flat bottom to a wide part, they'd stick so firmly that I'd have to take the glass plate off, and then use the underside of the edge of my desk break them free...essentially using my desk as a hammer! My printer's glass plate has a coating that's supposed to promote adhesion...well, it's certainly effective at that!Making it even worse, this was all using PLA...which was all I'd printed with, till just a couple days ago. But I needed to use PETG to print a part for my miter saw, and from what I'd read, PETG is known for not wanting to let go from the print bed. Well, I printed one set of my new parts, and sure enough, I had problems. The printing went fine...the parts looked good, but they were stuck down hard! One piece was so firmly stuck to the bed that it was destroyed getting it loose!!So I ordered this plate, and got it yesterday. After re-leveling my printer to account for the different thickness of the plate (vs the glass it replaced), I reprinted all the parts. When I was done, I lifted the plate off the magnetic surface, and the amount it flexed to do that was enough to break all the parts free! Everything came off easily, and intact, and didn't even leave any residue on the printing surface!One day isn't generally enough for me to make up my mind about a product, but this one job had 5 parts, and the difference between running the job with the plate and without it clearly shows it's solved my problem!Couple things I noticed...the size of this plate (I got the 310mm x 310mm size) is perfect for my Longer LK5 Pro. The adhesive magnetic part (that gets stuck to the aluminum printer bed) sticks very well. Make sure to align it carefully when you apply it...once it's stuck, it's stuck for good. I don't think you'll get a do-over if you mis-align it. I cleaned my aluminum plate with isopropyl alcohol and a microfiber cloth before I stuck the magnetic surface down.This plate is thinner than the glass it replaced, of course...even when including the adhesive magnet that sticks to the printer bed. So you'll have to re-level your printer.The magnet grips the plate VERY well! The plate is supposed to be stainless steel, but I wonder about that. Most grades of stainless aren't particularly magnetic, and some aren't at all. This plate is attracted to the magnetic surface strongly enough that it will pull it from your fingers as you're trying to align the plate. A good thing, in this instance I guess, but it does require you to carefully align the plate as you're placing it back on the printer. There's no sliding the plate around once it's down.Anyway, for me, this plate works perfectly, and it's money well spent.

Altamente rugosa, deveria ter um grão mais fino. De resto a aderencia é boa, apenas demasiado texturada.

The surface of this magnetic bedplate is amazing. I have a Qidi iFast printer. I loved the removable magnetic baseplate as it allowed me to refrigerate the print and have it remove easily. The problem was if I didn't get to it and the part cooled slowly, when removing, the baseplate surface would remove with it. This PEI plate is amazing. Whether I cool it quickly or slowly, the part removes easily. Also, the adherence to the surface is much better than my original plate. I have bought a couple of these plates to swap out and continue printing quickly. I have purchased another for an old Ultra3D printer I am upgrading the mother board and bedplate on. I highly recommend these magnetic baseplates. They are a great value and work great.

Estaba harta de pelearme por despegar las piezas de la cama caliente, con esto se soluciona, la base magnética adhiere muy fuerte y la placa consigue que las piezas se fijen aunque se quedan un poco granulados. Lo peor es que al pegar la base Magnética al cristal el grosor final impide que puedas fijar la cama con los soportes originales. En cuanto a temperaturas tampoco he tenido problemas usando la misma que tenía anteriormmete fijada

An excellent solution for anyone looking to print PETG. Those who have printed using PETG know two things. The material either sticks so well that it fusses with your bed and destroys it. Or, it barely adheres at all and warps right off your build plate. Textured PEI is the perfect solution, the material sticks perfectly during your print and the part pops right off when it cools down.As for the product itself, I'm quite happy with it. As far as I can tell there are a lot of sellers on Amazon right now selling these sheets. The only difference seems to be the extreme price delta. This appeared to be one of the most cost efficient solutions so I figured I'd give it a try. I'm really glad I did as it works an absolute treat. I rarely need to even remove the sheet off my build plate. Once the part(s) cool off they just pop right off. No glue, tape, hairspray, or more expensive solutions. Just the textured PEI, that's it. Happy Printing!
