USA Sealing BULK-CS-GFR4-42 G-10/FR-4 Garolite Sheet, 1/8" Height, 12" Width, 12" Length

Just as it should be.Working great for hinges on my F4u Corsair.

The material is very consistent in advertised dimension and rigidity. The manufactured surface is excellent. The handling of the material between its creation and me opening the box is appalling. I am impressed with the material strength judging my the marks that should be gouges in the surface. Whoever is handling this product for shipping after production is severely negligent at best. I would absolutely buy this again structurally but I do not want to work that hard to have a nice looking product.;

Amazing adhesion for 3d printing! Some scratches but that was expected.

Even if it had been flat (it wasn't), it was severely scratched and scuffed when it arrived, impossible to print on. If you're looking for a 3D printer surface, keep looking.

Absolute monster of a material to work with and get to size, but once you do it works incredibly. I believe mine started to warp or something though because it doesnt seem to be leveling correctly anymore

I finally took the plunge and ordered a sheet of G10 to use as a surface for 3d printing, but the sheet I received was extremely convex. Since it isn't metal and deflects when pressure is applied it isn't compatible with automatic bed leveling tools, so it isn't possible to just deal with the curvature. I'd recommend buying elsewhere if your purpose is 3d printing.

We used it as backing plate for sailboat hardware. The right stuff for the job. Extremely tough material. You need a cutting disk on a grinder.
