Not heard much about this and certainly not in the context of a BB so I thought I'd give it a go, bought a 300x300 mm sheet from 3dfilaprint.com. Specifically I'm looking for something to make my old K8200 as new user friendly as possible as I am preparing it for a new newb and young user as an entry into 3D printing. But couldn't resist trying a sheet on the BB first. Not the cheapest build surface in the world but they say it is maintenance free and long lived. I must say I popped it on a spare glass bed, reset the Z offset and did a PLA print which previously has given me a lot of problems with edges lifting off the bed. and it just worked. Seems consistent with the IR probe as well (though I haven't seen the problems others have experienced) gonna try it with Edge (as I have been really struggling with Edge and adhesion) Has anyone else used it ? The claims seem almost too good to be true given the range of materials (including tricky ones like Nylon) they claim it works well with.
