PC has good toughness (? ? The head can't be broken, it will only be knocked flat, so it won't be broken)

PMMA is brittle (if it is not thick enough, it will break or crack when it falls).

Transparency is similar.

I made a fully transparent flashlight lampshade. In the past, they were all acrylic injection molded, with a thickness of 2.5 mm The goods were sent to Germany, and the customer tested them. They fell 2 meters and cracked, and all of them were returned. After that, it was all PC injection molding, without any problems. The PC injection process is more complicated. The detour I took.
