Hello, I am currently trying to make a desktop ornament of Master Yoda using PLA filament. the details are not fully depicted so far, but I am confident that I can succeed

I'd be very careful using anything 3D printed in direct contact with food/medicines. Even if PLA is often advertised as a health safe filament, that's not quite true and it isn’t free from bacterial grow. Besides, apart from the filament, there’s the nozzle and other parts pf the printer. Only stainless steel nozzles should be used for printing parts in contact with food.

You may think that I'm too paranoiac about these matters and maybe I am, but still...

The biggest danger is bacteria building up in the layer gaps.

Yup, you guys make valid points!

I wouldn't use PLA for most food-stuff but I'm feeling that my risk is somewhat less because:

1) The materials are always dry
2) They both come from the store usually stored in loose cardboard boxes
3) They both tend to be pretty inhospitable environments for bacteria growth

So, while not 100% safe, this is one where I'm comfortable taking the risk.

There's the question of the nozzles too, Nifty. Those made from brass, copper or hardened steel may release small particles of different toxic metals into the printed part. That's why only stainless steel nozzles. are approved for 3D parts in contact with food.

On the other side, maybe I'm wrong, but aren't there some paints/resins/enamels made for the specific purpose of providing a health safe external coating to 3D printed parts.? If that’s so, even the nozzle question would be a moot point.
