Can anybody that uses flexible build plates tell me how thick their spring steel plate is? (not the bottom plate with magnets but the top plate that has the printing surface attached).

Going to try a DIY on my own but need a starting thickness.


Thanks

I haven't used a flexible steel plate myself, but a 0.5mm should give you something with enough flex to pop a print loose. High-strength spring steel would be ideal. If you are using mild steel, though, you might want something a little thicker (0.8mm?) to keep from inadvertently putting a permanent bend in it.

At work we use very thin sheets to apply solder paste to PCBs. When I'm back from my holidays, I can take a closer look.
I'm a bit confused about ( nonmagnetic?) spring steel on printbeds?

Spring steel can either be stainless steel (most alloys non-magnetic) or regular carbon steel, which is always magnetic.
