G10 FR4 Garolite Sheets 235x235mm, 1/16" Thick, Fiberglass Plastic Composite Build Surface Plate Bed for 3D Printers - 3 Pcs

Great results with petg! Went with light sanding suggestion and first layer went perfect with easy removal when plate cooled down. It’s not magnetic but you can make it one or use low profile clips. Definitely better than textured PEI.

These sheets are great. I've only printed PLA on them at this point, and they are perfect, just enough adhesion and it's easy to pop off the finished prints. I've found that with plain Garolite sheets like these, I need to wet sand them with 220 grit wet & dry paper, then wash with soap and water. I clean them with alcohol before each print. Every so often, after many prints, they seem to need a repeat wet sanding to keep adhesion at the right level, so try this if you're having adhesion difficulties. I'll add to this comment if I have any difficulties with other types of filament, but I have had good luck with a Garolite bed I've used for a couple of years, and these seem to be just as good.

Garolite makes for a great lightweight alternative for a 3D printer bed surface. On an Ender 3, which throws its bed around, this can make all the difference. It’s about 1/2 the weight of a typical magnet and PEI spring steel sheet. It’s also suitable for most all typical 3D printer filaments. It’s only about 1.5mm thick and it has a pretty smooth surface, so you may want to use a few extra bed clips and rough up the surface before using it for the first time. Overall, a nice pack of Garolite sheets for an Ender 3 sized bed.

Acceptable quality but too thin to be used for printing, they just bend too much and my machine will not print level on the entire sheet.

Not much to say about the product except I received 3 sheets. This product will last a lifetime

Had high expectations for these. Unfortunately so far they aren't performing s as expected.

These garolite sheets are basically the same fiberglass that circuit boards are made from. It never occurred to me to print on it, but apparently this is “the” substrate to print nylon. I don’t have any nylon, so I tested with basic PETG and it worked fine. Adhesion was so good (difficult to remove while still warm), I tried printing a part without a brim that I know has problems with adhesion, and it printed great. This is my first experience with printing on garolite, but I'm so impressed I'm just going to leave this on my print bed until there is a reason to change it. 5 stars.

Works really well. I was having bed adhesion issues on my ender 3, and this worked very well to fix that. While the bed is hot, th print sticks super well, as soon as it cools the print pops off pretty much by itself.
