| Nov 7, 2021 at 20:50 | comment | added | Kilisi | @ChinchillaWafers excellent, you should make that as an answer it's useful for people to know. I've found some good looking filaments online after your suggestion and will do some research | |

There are also some antibacterial filaments that would resist germs incubating in all of the cracks and voids and layer lines. Expect to pay 3x-4x as much as regular filament. | |

| Nov 6, 2021 at 21:55 | comment | added | Kilisi | @Abel thanks for the info, I have never printed anything, trying to get it right before we order the printers | |
| Nov 6, 2021 at 21:03 | comment | added | Abel | raw pla is a clearish white. raw abs is a fugly cream color. i never got any filament containing toxic pigment but i dealt with enough out-of-spec material (metal) that I'd ask the supplier and thoroughly test a first article before making a product i sold. want of repeat business usually exceeds want to cut corners. | |
| Nov 6, 2021 at 20:56 | comment | added | Kilisi | @Abel all filaments seem to be coloured, is that what you mean? Never seen any raw filament | |
| Nov 6, 2021 at 20:41 | comment | added | Abel | although it shouldn't be done in this day and age, it is possible to melt toxic additives into plastic for the purpose of giving it a color rather than just to color the outside of the plastic. do also beware of print settings as microplastics breaking off a print would not be good to breathe. ie anything can become harmful under the right conditions. | |
| Nov 6, 2021 at 20:34 | comment | added | Kilisi | @Abel no, no painting or anything like that, I'm just trying to work out if I'll need to line the masks with cloth or something. | |
| Nov 6, 2021 at 20:29 | comment | added | Abel | prolonged contact with face will pretty much always cause bad things. it beats prolonged contact with eyes though (glasses vs contacts). as for material safety itself, plastics and silicones tend to be considered enough to touch skin. do you plan to incorporate toxic pigmentation into your plastic as some toys did once upon a time? | |
