came across this youtube video showing flexible build plate I never seen before. I’m sure it is patented but anyone know or can guess what is the property of such build plate. it looks to perform amazingly well without heated bed

Their website says: “Optimized for PLA Printing“ so it could be pretty much anything that PLA sticks to.

It reminds me a lot of BuildTak’s FlexPlate System. However the FlexPlate seems like the better solution for a greater variety of filaments and it works with hot beds too.
