Shion.Kwoo Upgraded Specular Effect Pea Smooth PEI Sheet 257x257mm Spring Steel Build Plate Magnetic Flexible Print Bed for Bambu Lab X1 P1P 3D Printer.

The Shion.Kwoo Upgraded Specular Effect Pea Smooth PEI Sheet is a really good PEA steel sheet from all indications. I am still waiting on my Bambu Lab X1 P1P 3D Printers so I can only speak to the overall build quality and amy imperfections. I am happyato say that it is easily on par or better then most of the beds that I have. I can definitely recommend the iBambu Lab X1 P1P 3D Printer!

I used the Bambu Engineering plate for 1200 hours of printing before having to replace it because something got trapped under the plate causing the surface to be scraped by the nozzle. I bought this thinking it would do the job. The surface had defects in it after the first print on it. I bought the single sided PEA sheet. The adhesion is phenomenal. I actually had to start using a glue stick on it so my prints wouldn't stick to it as much when they finished. Maybe it would be great for just PLA, but PETG printing on it has completely destroyed the finish in less than 30 hours of printing on it. It is pealing in some places and completely rough all over. Luckily the rough effect actually adds to the realism of some of the parts I'm printing on it so I will use it for a limited amount of things, but definitely not worth it IMO. I have gone back and ordered a new Engineering plate from Bambu. I also have one of their black textured plates and NOTHING stuck to it until I used the nano-polymer glue. Then everything works on it.

I thought it would be nice to add a smooth PEI type plate to my setup. I use a Bambu Labs X1C and P1S 3D printers and I had great luck with the textured gold PEI plate the P1S came with.I'm not exactly sure what this "PEA" material is vs "PEI"? But it was a very thin, smooth grey/silver layer on one side of a basic spring-steel build plate. I think it may have been attached to it as a sticker, vs spray-coated on but I can't say for certain?I was only able to print on it 2 or 3 times before my PLA prints peeled up small sections of the material from the bed when I removed them. (I didn't use glue stick or hair-spray first, but that's generally supposed to be the advantage of these PEI type plates; you don't need to do any of that.)This wasn't a very expensive plate, luckily. So I'm thinking about just experimenting with printing to the uncoated spring-steel side of the plate after coating it in glue stick. I'm told this should work ok, as it's similar to the smooth aluminum build plates early 3D printers often came with.

While I like my Bambu Labs textured PEI plate, sometimes I may want a smooth bottom layer. While the PEI cool plate has worked well, it requires some sort of release agent to prevent sticking too well and peeling/bubbling the sticker. So when I saw this PEA (polyetheramine) plate with claims of no adhesives required, I thought I'd give it a try.Upon arrival, I was happy to see it shipped sheathed in sufficient amounts of cardboard to keep all but the most determined of delivery employees from damaging it in shipping. The plate itself is fairly beefy, a though a bit thinner than the Bambu Labs plates (0.87mm vs 1.09mm for Bambu's cool/engineering plate), but sticks to the magnetized bed strongly.While it lacks the "QR" type plate code to auto detect the plate (requiring you to clear the error to continue printing), it's simple enough to print out and attach your own plate marker if it's bothering you. The first layer inspection and flow calibration seem to work just fine, something Bambu's own textured PEI plate doesn't offer.While the marketing says it has improved lower temp adhesion over PEI, they also suggest using up to 60° for PLA, which suggests to me using the high temp plate profile (they don't indicate which bed profile to use, so I made an educated guess). With the high temp profile, I had excellent adhesion with PLA and PETG (the only two I tested, as they are my primary printing materials) that release fairly easily once the plate cools.The end result is a very shiny, smooth bottom surface. Now, there are plusses and minuses to this. With my textured sheet, the lines between individual rows of filament are hidden quite well. If you look at my close-up picture, you'll notice that you can see the lines between each line of filament. I think this is just going to be the nature of being so glossy and smooth, that the most minor of deviations in the filament can be seen.Cleaning is easy, with a simple wipe of rubbing alcohol on the surface.I'm pretty pleased with this plate. It takes needing adhesive/release agents such as glue or hairspray out of the equation while still offering a smooth, glossy finish. The price is a bit higher than your usual PEI sheet, but I'd rather pay a few extra dollars for the convenience of no glues needed.Edit: after several uses, I've discovered the plate gets permanent abrasion/adhesion marks from the bottom of prints, leaving an outline behind that I can just barely feel. The marks then copy ever so slightly onto the glossy bottom surface of the next print.

This plate is a good alternative to the oem plate for the p1p. This plate will leave a really shiny glossy finish on the print attached to the bed. Adhesion is fantastic sometimes a little too good lol.
