3D Printer Build Surface Tape 300x300mm for Creality CR-10 10S 3D Printer Heated Bed Sheet Replacement 11.8" x 11.8" Square Black(Pack of 2)

I recently purchased these as a bed surface for use on my 3d printer, and have been very impressed by how well PETG based filaments adhere. I use 60C as a starting point for the bed temperature, and have had very good luck with adhesion. As always, bed leveling is crucial, and getting the this surface tape perfectly applied was quite easy. I traced the surface with a Sharpie, cut it on a bevel with a hobby knife, and applied it using a roller to burnish/smooth the surface.I've only been using it a few weeks, and cannot yet speak to its durability, but have been impressed with the quality. At roughly five bucks a sheet, I consider it a very good value. I wish that I knew the chemical makeup of the material (PEI? something else?), but the adhesive seems to be good quality. This product leaves a nice, fairly consistent finish on the bottom surface of prints, which is neither pebbled (like blue tape), nor high-gloss (like kapton). After struggling to get consistent prints on a glass bed, this has been a pleasant surprise.

Used on my cr10. Out of the 2 pack one worked great and the other not so much. Also when trying to replace the bad one. It cracked the mirror I used it on. So out 2 mirrors. Cost me more than the price of the item. I cant return it because well, it would have glass adhered to it. And that's not safe. I tossed them both in the garbage. Also thicker than most build surfaces I've used.

The prints don't stick any better with this.

For the price I can't complain too much, but I can already tell after just a few prints, that these mats aren't going to last as long as others I have used. That said, they are about half the price per mat as others, so take that as you will. I will probably buy slightly better ones next time.

I've completed several prints with this build surface, and it has worked out pretty good thus far. The item came as described, but is slightly smaller than the overall buildplate. There is a 1/4 inch rim around the buildplate that's not covered by the item.However, PLA adheres to the surface extremely well. Almost too much, in fact. Removing prints can be challenging and I don't recommend using this for small, delicate, parts. I could be going about it wrong though.In conclusion, it's a decent build surface for the money. I would probably go with something else if I had to buy it again, but I don't regret my purchase.

I have tried many different print surfaces with many different materials and this one performs as well as the most expensive that I've used.On my heated bed, it does stick VERY well. The trick is to let your print cool completely and it should come off easily with a small wiggle or twist. No more overpriced surface mats for me.

Horrible. Useless.Cold glass has better adhesion.Painters tape of the cheapest variety has better adhesion. I suggest also getting a Qt of acetone, when buying and using these. 1 hour of hard labor removing the adhesive from my bed.

I heard about these through a 3d print forum and decided to try them out. So far everything is great! I haven't had to use painters tape, hair sprays, ABS juice etc. The prints stick really well.I don't write reviews because I never know what to say but I would recommend these to anyone who is 3d printing and would like to save some money.
