FR4 / G10 Garolite Build Surface and Ultra Rugged Flex Plate for 3D Printers by West3D

marginal adhesion with Polycarbonate

After many prints and bracketing bed, nozzle, chamber temps & Z-offset, I find this particular garolite bed to be marginal for polycarbonate. PEI with no release agent or adhesive provides the most consistent adhesion for odd geometries with varying bed contact, so far. This garolite bed was supposed to reduce the cleaning and bed prep rituals. Sadly, it did not. This review pertains _only_ to polycarbonate, no other filament types were tested.

Love this plate so far. Smooth and just enough stick.

I put it on my ratrig vcore4-400mm. Surfaces are real smooth but not glassy smooth. Just enough in my opinion. Can't even see the lines. I have only printed pctg and petg on it and have had no issues so far with smaller parts. Haven't tried asa or anything large yet.

Best there is

Garolite/FR4 build surfaces have been my go-to for any hard-to-print materials for a while now. I think I have 3 of them across various printers. This one is no exception, prints stick hard, and pop off once they cool.
