This plate is a 4.5mm thick double layered fiberglass laminate sandwiched into an acrylic substrate. Ninja plate is designed to be attached to your build platform.

The plate is very strong and is far less likely to break than glass. We doubt you could bend it far enough with your bare hands to crack it, but we recommend only bending it enough to aid in removal of your print.

How conductive is it relative to glass, and what is its surface roughness?

Edit: thermal conductivity, I meant.

3

How flat is it, and what sticks to it? It is rigid enough to resist ABS warping?

4

Only 70C? No good for keeping ABS from warping then? I usually use 125C!

5

All depends on how well the surface conducts heat and adheres. When I was playing with marble beds I had to drop down to 85c because the convection was so strong it was not just keeping warping down but melting the first 15 layers!

I’d be curious to see some user reviews.
