Review: 8mm super rigid and easy to work - I bought this thicker 8mm plate for an auxilliary fence on a miter saw because I thought some extra thickness might be needed for rigidity. This G10 black is very dense as expected (heavy) and very rigid. I probably could have used 6mm and been fine even with recesses for mounting screw heads. I've worked a lot with cutting and sanding all types of phenolic sheet and the standard green/tan G10 material as well as carbon fiber plate. I expected this to be hard on tools and difficult to work with after primary cuts but it really worked like a breeze, just as easy as any phenolic. You will get some fiberglass itchies if you aren't careful but the cut edges on the material itself are clean and without any fuzzing or chipping. This was true for me with an aluminum cutting circular saw blade (-5° TCG) as well as a little carbide grit abrasive wheel on the DeWalt 3" cutoff tool - it even routed extremely clean with roundover bits and a flush trim bit. A decent HSS Freud forstner bit did four shallow holes/recesses and didn't seem any worse for the wear but I was expecting it to be trashed. This is definitely more abrasive and harder on tools than other plain plastics and resin composites but not as bad as carbon or as bad as I expected it to be. I think the black might have some graphite in it but I'm not sure. The chips/flakes were light and flexible just like what comes off of nylon and some plastics. The saw/sanding dust was just very fine powder like phenolics. Do wear eye and breathing protection because these particles can be quite dangerous if you work with it much, and skin protection is highly advised unless you like the itchies. Good stuff and I will buy this again. I wish they had some other precut options like strips/bars. By the way, all edges were very flat and smooth, all corners darn close to perfect 90°, sharp crisp edges...nice.
Review: Not too bad, a little soft compared to some of my other fr4 - Pretty decent, works fine as a build plate on a printer. the thickness keeps it from warping up much under shrinking abs/nylon prints. It is a little soft compared to my natural colored fr4, a bit easier to dent, and if your first layer height is low it will mark a bit where the print was. Has held up well to use with TAP probing though. Adhesion was an issue at first even with a sanding, scrubbing at it with an alcohol soaked microfiber until it came back clean fixed that, and has been fine since with just a quick wipe before a print. Overall satisfied.
