CCTREE 3D Printer Build Surface with 3M Sticker3D Printer Heated Bed Sheet for Creality CR-10S S4 400x400mm (Pack of 2)

I used to LOVE these CCTREE sheets for my printers. Nice texture, and the prints would stick nicely to my flexible steel sheets. I actually added a little glue stick to make prints easier to remove. I have a custom printer that has a large 400x300mm build area, and used to have a couple of these CCTREE sheets on it (300mm, so I used two put together and cut to fit), and it worked great for over a year. I recently changed the z probe, and during my calibrations, accidentally scratched up the build sheet with the nozzle.Anyway, I was happy to find some more of these CCTREE sheets in the bigger 400mm size last month on Amazon, so I immediately ordered a pack. I removed the old sheets (which took a lot of effort), cleaned my flexible metal plate with a razer blade and some isopropyl alcohol, and then applied one of the new sheets. The next day, I noticed the edges of the sheets popping up off the build plate, so I stuck them down again, only for them to pop back up after a day or so. I started using clamps, but the sheets would then bubble in the middle and on the sides, and ruin the print.So I took off that sheet, flipped the steel plate over (never installed anything on that side), and stuck on a new CCTREE sheet. This one seemed to stick better, so I was excited to try a 2 hour print in PLA. when removing the print, I noticed a bubble in the middle of the sheet. I rolled it out with a rolling tool and made sure it was stuck down, and started another print, this one was going to take 5 hours. I checked on the print 3 hours later, and the edges of the sheet were lifting AGAIN, which in turn warped my print, which is now useless.These sheets USED to be good, now they don't stick and are useless. They must have changed the adhesive on these, because the old ones I have still work well. don't waste your money on these until CCTREE fixes the lack of ahesive.

Still getting to know the CR-10 S4 with the 400 mm bed. The first print had the bed way too high so the extruder scraped the build surface. The build surface is pretty tough, so it came out flattened and polished. Then because the melted PLA was pressed in so firmly, it was difficult to get the object off the surface, and even more difficult getting the remaining PLA skirt off. I had to use a heat gun to soften the PLA and scrape it off. Once I got the printer bed height properly adjusted, the prints adhere just right. I did have one print that tilted, because we didn't stick the surface down, we just used clips. So now we will remove the backing and stick the surface down to the glass printer plate; which might be tricky since the surface is so big. It would be nice if there was a version with moderately sticky adhesive, like the adhesive for Post-it notes.

To thin to be clip to the bed. It would pull the sheep up if the filament curved to much. To much trouble to remove if I use the sticker. It won't save you time and giving you more trouble than help. The sheet is too thin to be use for a long time and replacement it is a pain. I would save money, time and trouble of replacement if I buy a 1 mm thick or more even if it cost more

Bought a different product but it was going to take awhile to get in, wanted something as the glass wasn't working well for me, so I bought this because it was cheap and I could get it quick. I have been extremely happy with this product, I use hatchbox filament and this sticks well, almost too well. I sometimes have to tap my scraper to get stuff loose. Its rare when something doesn't stick, (usually very small part) but I usually wipe it with alcohol each day before I start printing as well. I always make sure my bed is level and close, and print at 60C for pla.I just stuck this to my glass because I wanted to be able to remove it easily, almost wished I hadn't bought the other product as this works just fine for me.

Because PLA sticks so well to the sheet, it takes a bit of elbow grease to get the print off the build plate. So, I use flexible metal heatbed and placed the CCTREE build plate sheet on it - works great - haven't had first-layer issues since using CCTREE sheet. FYI to CCTREE: for ABS prints, the build plate sheet began to lift from the heatbed at 100-110C pulled up by the ABS print. It would be a nice fix if your build plate sheet could withstand high temperatures. It appears that most of the ABS print issues are for larger ABS prints. I have had successful "small" and "less than 2hrs" (i.e. "Benchy") ABS prints with 70-90C heatbed temperature.

Fits my CR-10 Plus like a glove, seems to work well.Update :Only one brand Filament that I have seems to stick well to this.have tried with my other rolls and it slides right off with no adhesion.I had it stuck to the Glass Bed with those results.Changed from 5 Stars to 2Tried to double check all over the companies web site and there is no support for this item, Trying to verify it was suppose to stick to the glass or directly to the Aluminum heated Plate of the CR-10

This build surface has amazing adhesion. I was so pleased with the original one that I received with the printer that I ordered two more for it. I had one print stick so well to it that I was unable to get it off, so i tried to peel the surface off the mirror, but ended up damaging the surface. Replacement build surfaces work amazing! No hairspray, glue or tape needed, just level the bed and print away!

I tried it for more than a dozen tests with PLA and could not get good adhesion. Tried both with and without glue stick with no success. Not sure if it the brand of PLA or something else as the smaller size sheet seems to get much better reviews.
