I refer you to my previous answer :-)

It's your choice and much safer - on average - than getting out of bed.

We live in a world currently ruled by health and safety regulations. It's a small, occasionally sad world.

You know that there are at least two working and viabley economic flying cars in enxistence. But alas they came too late - regulations no longer allow them to fly in our society.

Likewise many things that are passed as safe to consume - really aren't.
Realistically the actual danger factor from 3d printed items for food use is so low it's not worth considering.

It's Up to you.

I know I'm not going to worry about it.
