It’s just a surface to air missile. 100 is quite a few, but considering how drones are used in this conflict, it’s probably not nearly enough.
They are likely reserved for last resort air defense closer to cities or areas where they really need to push back the Russian air force.
Patriot batteries are a bit on the expensive side, so their use is likely limited. If I am not mistaken, Ukraine did get a few batteries from other NATO countries and not just the US.
There is a caveat, but yes: By definition, 3D printed parts should not be considered food safe.
Single-use cookie cutters are generally OK if you don’t use them multiple times a day every day.
There are probably minor chemical risks but it wouldn’t be in high enough quantities to kill you. There isn’t really anything inherently food unsafe with PLA, ABS or PETG.
Bacteria is a much bigger risk during reuse because you can’t fully clean the prints between the layer lines and other surface defects. The plastic generally won’t survive a proper sanitization process either.
What your own risk tolerance is for plastic additives is up to you. If you do print a cookie cutter, toss it after you are done.
