Hello, I need your answers

Hello. I'm going to print some plastic caps that will be used for some spices, salt, vinegar etc.

Which material(filament) is more suitable to use for 3d print? Sorry for my bad english.

PLA, ABS or Nylon are all good choices for this. PLA is the easiest to print and will look the best.

I recommend 2 colors to print a "S" on the salt for example. Print the letter first .2mm thick as one part/print. Then change filaments and print the other print on top with the bottom layer .3mm thick. Dont' worry about subtracting the letter from the cap:

Am I the only one who is paranoid about using printed parts for stuff that is in contact with food? I just don't feel like it's a good idea.

Thanks for information, but is PLA a good material to print parts that are in contact with food? I mean, can the PLA in contact with food to be dangerous to human health?

There's also a brand called Purement that makes antibacterial filament http://www.3ders.org/articles/20150326-korean-plastics-manufacturer-bnk-unveils-new-anti-microbial-pla-filament-purement.html

I'm in a factory that makes food packaging for companies around the world. You wouldn't worry so much if you see how most packaging is made. you may even prefer to print your own

Could be it's not only the material but also that a print is build in layers thus never giving a real smooth surface and more room for bacteria to build up? Does that make any sense?

I get what you are saying but heaps of people use plastic chopping boards, most of which had rough textured surfaces. Then they create cut marks in it not to different to layer lines.
