g 10/ FR 4 Garolite Sheet, 2 Pcs, 1/16" Thick x 12" Wide x 12" Long

This stuff just works. High quality and it adheres to 3m double sided tape easy. I use it to make garolite 3d printing plates.

2 pieces! great price! this is the perfect thickness not like the flexible first kind that was floppy and paper thin--this is about .85 mil and rigid, but can bow just a bit as you want paired with spring steel for the magnet bond on x1 bed. Both sides were protected with plastic cover and perfect surface. The rigid sheets can be cut to size with the right tools--I was able to score with many passes of utility knife (it does dull the blade as expected) and then safely snap. I only cut to square bed part for 2 straight cuts and let the steel sheet cover the front overhang and the back filament wipe area ( I do add a little foil tape to the wipe part). I used a spring steel blank plate to bond with 3m sheet adhesive and it works perfect. I don't worry about plate detection and turn that off in printer settings, just level the bed when you print and use the smooth plate setting-- I tend to go about 5-10 degrees over the PEI smooth plate just to get the full plate warm. on ABS or PETG. No surface printing glue needed the heat holds it and it cools and releases. Did not need to sand this one yet. If I do later with time, I will refresh it with 1500 grit sandpaper, I recommend wet sanding paper to prevent more dangerous dust when sanding, or use protective gear.

As advertised. Worked perfectly for my application (building a custom battery pack) and I would and likely will buy again for my next build.

Works great for the bed on my 3D printer. It was a little thicker than I expected, but that's my own doing for not checking. Sanded it down a little bit with some 120 grit and now my 3D prints stick to it very well. They are also pretty easy to remove.

Seems to work great for 3d printer. Worked perfectly the first time. The print was firmly stuck on there when hot and slid off when cold. This base plate for my 3d printer was the last hope before it landed in a landfill or donated (it was an old printer on its last days) can't tell if the heat warped the sheet or I suck at manually leveling the printer that never came completely flat in the first place but I didn't end up using it enough to give it 5 stars.

Used my table saw to cut this down to 9.25 x 9.25" to fit my Ender 3 S1, sanded one side with some 150 grit sandpaper, then cleaned with dawn dish soap and warm water. So far my Nylon (PA) prints have stuck without warping.

Serious popcorning issues above 200 centigrade, looks OK mechanically but don't try it at high temperatures.

Arrived fast, nice and flat, with protective film as well.

This is what I needed to complete my battery build project. The material is strong, temperature resistant and a very good insulator. 👍
