Ok, can someone please translate the Youtube clickbait title into more reasonable language? Are they surprisingly good? OK looking? Reasonably cheap?

I doubt they are groundbreaking enough to border on mental illness being a likely factor in the development phase.

I love the idea of this. I don't think I would realistically ever buy or do this, but the process is clever and looks like it works well.

Would those be food-safe? I know normal 3d prints are porous, and that leads to bacterial/mold growth.
