1pcs G10 Glass Fiber Sheet 400X500X5.0MM for RC Model Black Color

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.

Works great. Prints pop off very easily once cooled. Also, the base layer is much smoother.

Good product, very sturdy

The prints come off easily after the sheet cools down, with some resistance but not even close to the same level as my stock Ender 3 bed. Spotless after 2 prints.

This sheet will not magically fix a wobbly, un-level, or warped printer bed (all standard features of the Ender 5 as it was shipped).Printing bed supports, changing from springs to silicone support spacers, shimming the low spot with a piece of foil tape, and then manually tramming the bed made the standard magnetic surface work great with PLA+ / Pro. This plate was still a bit finicky on some prints, but good.On my Ender 5, the CR touch was a total disaster, but switching to a silent board and new Marlin software turned out to be a real winner. After tramming the build plate manually, and adjusting the limit switch for Z axis, the build plate has not required leveling after many prints. This G10 sheet is a strong contributor to that success - it is very repeatable and stable.For me, a nice coating of water soluble hair spray, dried in the oven with its "dehydrate" setting was the final touch. If a print is a bit stubborn, some water makes it fall off. A coat of hairspray lasts several prints.With the small improvements in my lowly Ender 5, and this build surface, printing is reliable and good with no elephant foot.A very worthwhile upgrade for sure, but no substitute for the basics.

Used as a 3d printer bed. Kind of interesting to cut with only a razer blade, but it worked! Not sure if this is quality stuff of not, but I have extra.

Arrived fast and in good condition.Perfect size for my Tenlog 3d printer - literally a perfect fit.Right out of the box everything sticks well and pops right off when the plate coolsDefinitely will buy again

A quick google search will say Ender 3 Max Neo has a 300x300 bed, but the actual size is 320x310 which this seller doesn't offer. I'm 10mil short on one side. No fault of the seller, just putting this out there.First print didn't stick. Surface is very smooth. Will try wet sanding. No complaints on the cut or sheet quality . All good there.
