Public Service Announcement: Vision Miner NANO Polymer Adhesive and BIQU Cryogrip Pro do not play nice together
Did a large print with polycarbonate and had problems with this part warping so I covered the sheet with Nano Polymer Adhesive. To my surprise it worked too well. Removing the part from the sheet also removed part of the sheet (pun intended). I can now see see shiny bare metal where it used to be blue. Fortunately the sheet was inexpensive and I have spares. For this project I will need to use my Garolite G10 sheet which is close to indestructible.

I already suspected that the Cryogrip plate wasn't a magic solution for every filament out there. It seems to be perfect for PETG and PLA but PC and PA.. not that good. Frankly I prefer powder sprayed plates to the ones coated with a sheet of PEI or a similar polymer, where it's easier to damage the surface if it's difficult to remove the model from the plate.
For PA I only use the Prusa PA powder sprayed plate. It's perfect for Prusament PA11-CF and works also well for other nylon based filaments that I tried, although those need sometimes the use of 3Dlac to avoid warping. In my book, large parts in PC are the most troublesome regarding adhesion/warping. I use a smooth plate, Dimafix adhesive and a large brim, although the best solution is to use ASA or PA-CF/AF instead of PC.
RE:
Respectfully disagree. I've printed a ton of ASA, PA (PPA, PA6, PA12-CF, PPA-CF) an PC (both blend and CF) on the CryoGrip. I regret wasting money on the Prusa PA sheet, especially since I had to keep it away from solvents like IPA.
The mistake I made in this instance was trying out glue in the first place on the CryoGrip. Without the glue the PC parts stick fine. Since I was printing extra large parts for this job I was concerned about warping so I thought of giving it some extra adhesion. It indeed warped but instead of detaching, pulled the corners of the sheet off the bed but didn't damage the sheet until I removed the parts. I tried it again without the adhesive and again the parts warped the sheet off the bed but did not damage the surface this time after I removed them. I think the CryoGrip will still work, I would need to clamp it to the bed with clips or extra magnets.
So this is why I've switched to my G10 sheet because it is mounted to a rigid steel plate and not spring steel. With the G10, the parts plus adhesive stuck to the sheet without warping. I was able to remove them (with great difficultly) but they weren't warped.
I still believe that the Cryogrip is still better than anything Prusa provides and is also 3x cheaper (for me). The only filaments that don't work with this sheet are PP and POM which is understandable.

Wow... Even my G10 sheet with a steel plate as the base (not spring steel) the parts are warping the plate. These are 4 long bars with 5% gyroid infill and 4 perimeters. I may need to rethink this. Perhaps print 1 at a time diagonally.

Prusa PA powder coated steel plate is very expensive but, in the long term, well worth the investment and works better than a garolite sheet (which I also tried in the past).
About the Cryogrip, as all the plates coated with PEI is exposed to damage if something goes wrong ( as you experienced ). With glue you get warping and damaged the surface, without glue you still get warping. If that part in PC gives you so much trouble why not try an alternative filament ?. ( PC-CF, PA12-CF... )
BTW Have you tried Fillamentum PA-AF80 ?. It's VERY expensive, but nothing beats it for sturdiness, resistance to impact, abrasion, endurance to chemical products and high temperatures. Being filled with aramid/kevlar fibers it warps a lot less than pure nylon or PC and prints at relatively low nozzle temperature ( 240-250C).
As you see, I still disagree with your opinions, so we must agree on our respective disagreements .. 😋

There were only 3 attributes driving my filament choice: heat tolerance, impact resistance and color choice. So it was down to ASA or PC. The PA-GF's didn't have the colors I needed and was too expensive for my application. Let's say my parts have to survive accelerating to Mach 1 (or higher) and possibly (hopefully not) impacting the ground at around 60 m/s.
I like the CF filaments... and the fact that they come in any color as long as it's black 😉
I've finally been able to control warping of the part by changing the orientation so it's diagonal across the sheet. So I'm satisfied with the PC results. I just find it fascinating that it's very hard to bend my G10 sheet by hand (since it's not spring steel) but a few plastic parts stuck to the sheet can bend it easily.
So basically it doesn't matter if I had used a Prusa sheet or the Cryo or my G10. The parts stuck to the sheet, when the parts cooled and shrank, the bed adhesion was strong enough to bend the sheet. With or without adhesive.
