This is an amazing upgrade for my two ender 3D Printers. No more glue sticks, PLA sticks perfectly every time, so much less of a hassle and I use it with confidence. A simple wipe down using rubbing alcohol cleans the surface of any greasy fingerprints. Parts come off clean and easy. The best plate build I've ever used. I'll buy 2 more soon as backups for future use.

No more glue or hairspray! Don't need it. Just keep it clean. Let it cool completely and it feels like static cling holding it down. This piece fits the Ender3 build plate perfectly

I ordered the 200x300x3.0mm size, and the thickness was actually a bit greater than 3mm, so it was suitably sturdy for my task: supporting an array of large electrolytic capacitors for a high-voltage power supply's filter board. Using a good quality 60-tooth blade, the 3mm thick board cut very cleanly on my table saw, but for cutting the 1mm and 1.5mm sizes I would probably use an even finer blade. This is good material, and I will be ordering more of it in the future.

I used this material for fins on my model rocket. Worked great. Hard part is cutting it. I went through a handful of scroll-saw blades.The rocket flew to 2443 ft allowing me to get my L1 cert. Yep, it works.

The sheet came curved, deflected. It cannot be used. How would one use a curved 3d printer bed... Do not buy

For the past several prints I’ve been having all sorts of adhesion issues with my trusty glass bed. Tried everything- re-levelling, different filaments, glue sticks, cleaning with isopropyl alcohol, etc. nothing would work. Decided to give this mat a try and instantly the problems went away. The only time I had one fail was when I was testing to see how far off the surface I could go for the first layer and still get a good print to stick. Turns out, it was decently far.I read that some people had issues removing the print afterwards. I just let it cool and you can actually hear it let loose as the temp drops. Most o had to do was stick the scraper under a corner to pop it off, and that was just because I had the first layer paint extremely close.This thing took care of the adhesion and elephant foot issues, and leaves a very smooth bottom surface. Highly recommend.
