Please note that this website is currently a work in progress! Lots of interesting data and statistics to come.
Interesting video, but I think the hype of PEI covered steel sheets partly due to the sheet still being magnetic
I'm using FR4 for years now on my smaller printers. It's great but I much prefer Pertinax for bigger objects with more bed contact as it releases a lot easier and prevents warping a bit better.
What's old is new again.
been using FR4 for like 2 years now. was using PEI on mirror before, but removing prints ruins the glue underneath. was going to switch to magnetic PEI coated sheet, but the FR4 has been working so well that there's no point in changing. I just remove it from the printer and bend it a bit and the print pops off, even if there is a little glue used.
just make sure you mark one edge of the material with a marker to distinguish it as the "front" of your build surface, and always install it with that part facing the same direction. if your build plate is already not "perfectly" flat, this will ensure whatever mesh levelling you are using is as close as it can be.
I can't even remember the last time I adjusted baby-stepping on Z-offset. I've just been pressing print and walking away now for almost 2 years. Have not had a single print failure in over that time.
Bought 12"x12" sheet of G10 from McMaster. Went for the "tight tolerance" version, which states a +- 0.005" flatness. It was $38 plus shipping.
When it arrived, it was clear that the tight tolerances only applied to the thickness, it was close to 12" square, but none of the corners were square. It also had a sanded finish, instead of the polished finish featured in the video.
I used the scoring trick to trim it down to size for my CR-6 (though I didn't score both sides on my first cut, so it was a bit jagged). I ran a chep cube first just to make sure the PLA wasn't going to permanently adhere to the sanded surface, all good.
So far I've been printing on it for the past week with no issue. Good bed adhesion during the print, comes off easy once the bed cools (I haven't tried pulling off on a hot bed yet). Bottom finish seems fine, it's not the mirror finish Maker's Muse got, but that's fine.
I haven't seen any issues yet with the nozzle marring the sheet. And the CR-6 is the worst case for this, since it bumps the hot nozzle into the bed as part of its ABL.
My g10 keeps warping. Bought the G10 surface from 3d maker
