YOOPAI PEO+PEI Build Plate for Bambu lab, Double Sided 257×257mm 3D Build Platform,Textured PEI PEO Sheet 3D Printing Bed for Bambu Lab A1/X1/X1C/X1E/P1P/P1S 3D Printers-Black

I got this plate as both a backup and to get the patterned side for my A1. The plate fits perfectly and is of same exact size as the original Bambu plate. The textured side feels exactly the same as the original, but again primary purpose for me is to have the fractured patterned image.One of the best things about this plate is that I did not need to issue an auto-level. Using the same profile from the original plate worked just fine and it's now just down to a swap.Adhesion wise at first it did have a little lift on a box that I made from PLA. The corners did not stick as well as the textured PEI side. No finger prints/etc could be seen on the plate. Cleaning with a spray if isopropyl and wiping up did seem to make things better so perhaps there's a layer from manufacturing left on there. The next print was a hueforge dragon which came out perfectly with no corner lift.Using PETG on this seemed to work fine on the PEO side with a small print using the correct bed temp. The part came off without issues after giving it a standard plate bend.A more difficult print, for adhesion, is a flow rate test with a 5mm brim (this is a U shape that gets printed progressively faster). Post cleaning and with PLA it worked out well and did not come unstuck. It did not, however, take much to pull it off right as it finished so there is some risk of peeling even with PLA.Despite the feeling like it may come off at any moment because it's easy to pull off of the hot plate, it has not functionally failed over several prints.

Textured PEI side works great with no issues. The patterned side takes some tweaking. It doesn't always have the same level of first layer squish or layer adhesion so your surface quality can vary. If you don't have your flow and pressure settings fine tuned, you'll see some lines look a little underextruded or you'll see wavy line overlap, commonly associated with overextrusion. Functionally, it's not too big a deal unless its actually impacting your functional part's dimensions. Aesthetically, you'll be able to see the flaws under the patterened sheen of your printed part. Compared to other PEO surfaced plates, This one required alot more monitoring and tuning. This might be related to type of pattern and as the smaller triangles on other plates work a bit better and the carbon fiber weave style seems to almost work as well as textured PEI plates. Its a very nice plate, but just keep in mind- its not going to be as plug and play as your typical PEI textured plate.

The PEInside of the sheet is great, possibly working well on par with the OEM PEI sheet. I’ve had great results. The opposing side has a nice design, it needs something with a decent surface area to get the full effect. Any light colored filaments (I did a white print at one point, doesn’t really show the design at all except at just the right angle and light. A darker filament like in the photo works much better. Took some adjusting as you almost need to over squish the first layer to get it to really display. Take note you need change your setting in the slider to have a higher temp, the PEO side is not strong with adhesion with the PEI settings.

I got these for my X1C, since it is always good to have some extra plates to use as you are cycling through prints, but sadly these plates leave a lot to be desired. First off, they are much lighter and thinner than the OEM plates, and secondly the adhesion is terrible on both sides. I suspect that it could be the thinness is just too far for the ABL to set to, but then again, I did get some adhesion here and there, so I think it is more of the texturing process that they are using. My initial reaction is just meh, but I'm going to hold on to this and try cleaning them to see if perhaps there is a coating or something reducing the adhesion, and may try doing some manual tramming to bring the head in closer to the plate. I'll also try a couple different filaments to see if anything will stick. As you can see with my native plate, I got solid adhesion with no effort compared to this one which the fan actually ended up blowing the parts around because they weren't sticking.

I was wanting to get into printing petg. I've been using PLA on a black diamond bed but warnings are that petg can be damaging so I decided to try this one. I had a bit of trouble getting good adhesion on the black side but it sounds like cleaning it with alcohol may help with that. The gold side worked well (albeit with a less pretty pattern) and I was able to get a decent benchy on the third try. It does cup on the gold side without a magnetic base but it is designed to work with one so that's not a negative. I'm pleased with this item.

With this YOOPAI printer bed, you get two beds for the price of one. The PEI side is the familiar golden color with a pebbly texture that can impart a vaguely leather-like texture to your 3D print. The PEO side is black and has random Star Trek symbols on it that will transfer to your 3D print if you have a large contact area with the bed.I have only used the PEI side for now and it gives the excellent adhesion that PEI is known for. After it wears for a while, it may need some additional glue but brand new it works great.I noticed that on the PEO side that there were some slight scratches when you held it up to the light in a certain way (see it circled in the photo). They didn't wash off with IPA or naphtha. They are slight and you probably wouldn't notice them in the final print, but I would like to see some more stringent QA/QC at the factory.That aside, I think that this build plate is a great value and should give years of trouble-free operation.

I have printed about 6 items so far on the bed and have not had any sticking issues at all. Without any helps like glue as well. I did wash the plate before using the first time. I have printed the airplane thrower that is pictured which has some narrow areas as well as some hueforge prints that are huge squares. No issues. The design from the bag shows up quite well, especially on black filament. It gives it a nice glossy feel as well. Definitely worth the price.
