Check price on AmazonCold-plate adhesion that makes PLA and PETG stick
CryoGrip Frostbite is the plate we reach for on Bambu beds when we want strong first layers at lower bed temperatures. Parts pop free with a flex, and energy use drops versus running a blazing PEI sheet all day.
Who it's for
P1S / X1 / A1 owners who want fewer warps and easier part removal.
Pros
- Excellent cool adhesion for PLA/PETG
- Easy flex release
- Energy-friendly bed temps
Cons
- Sized for Bambu beds
- Not a universal PEI clone for every machine
