Is this another solution for food safe 3D printing? Nonoilen filament from Filamentum.

Nonoilen filament by Filamentum may be another solution for food safe 3D printing. Since I work on Food Engineering Department (at uni-mate.hu) and I am trying to implement 3D printing in my workplace, it is very important to find solution, where 3D printed object can have direct contact with the food. So far, I tested coating with epoxy resin, smoothing the object, using antibacterial filaments etc. Nonoilen filament may survive 110°C, this means object can be placed in boiling water or in dishwasher on high temperatures. The printability of this material is similar like PLA. I also did some mechanical tests too, since manufacturer claims, that this is tough material. There is one error in video, unit of bacterial test is CFU and not CFU/cm2, but the ratio between two tests is correct.

As we talked before I think pasteurisation will be practical answer for this. In wine brewing pasteurisation used for extend bottle selflife but due to boiling ruing taste we are using 50-60 C bath for one or 2 hour to kill most of the yeast and bacterias. So 50-60C bath with petg for one or two hour will kill bacterias. By the way thankyou for this amazing video.

As you said, impressive temperature spec. Thanks for finding this material. Do you think it will survive a dishwasher, they have a drying period which also sanitizes the contents. I think they only reach about 80C but I don’t know if that’s a requirement, many plastic containers deform when I was them

I did more detailed video about that topic: kzfaq.info/get/bejne/oqykgKyglZbYlo0.html BUT what is not mentoned in that video, cookies will probably be heat treated (baked) and with that you will kill almost all bacterias. If cookies will not be baked, that definately I don't recomend it.

@@MyTechFun I think that I've read somewhere that even if you "kill" the bacteria it's "body" is still there which is still not good. It seems like that is not the case, but there are some kind of toxic spores that can survive boiling for longer than ordinary bacteria.

@dingdingdingdiiiiing 2 жыл бұрын

@ bacteria don't have spores, funghi do. Bacteria excrete toxins which in some cases gives us most problems and those excretions don't disappear with boiling. Perhaps this ia the problem, not the remnants of bacteria ...

@gnydick 2 жыл бұрын

Keep in mind, the process of 3d printing is not food safe. There is possibly lead in brass nozzles and other unknown chemicals in the entire filament path.

@nightclaw999 2 жыл бұрын

Is that truly an issue after thoroughly washing easily dissolvable particles and chemicals on say an object of the size of a cup? We are talking like 20g of filament. Even with single digit percentage contamination (which would eat away your nozzles extremely fast) and consuming the entire contamination after the first 3-4 cups, you would still be below the amount of lead, that is considered "safe" (or also "lead free") in drinking water. So I don't really see how lead contamination really is an issue on this scale, as long as you don't eat what you print. Secondly, having filament that doesn't deform when boiling combined with epoxy coating covers up for any contamination and you end up with a product that is even dish washer compatible, which is a huge plus.

@MyTechFun 2 жыл бұрын

I agree, and I already discussed this process in separate video (linked from this one) kzfaq.info/get/bejne/oqykgKyglZbYlo0.html

@nightclaw999 2 жыл бұрын

PS: I took values for "safe" lead contaminations in drinking water from this source: www.epa.gov/ground-water-and-drinking-water/basic-information-about-lead-drinking-water They (US environmental protection agency) state, that up to 0.25% by weight lead contamination in plumbing is labeled "lead-free" and "safe". I misread the values for "by weight in water" which is a false claim. I'm sorry about that. Yet they also state that 15 parts per billion lead in water is the limit above which action needs to be taken. If we interpret this as "below is fine", we end up with 15mg/l of lead. 1% lead contamination by weight in a 20g cup corresponds to 200mg, so if you do not replace the cup before drinking 14 times (uncontaminated) water from it, you on average stay below this threshold. This is more than the 3-4 cups from my first post but still realistic for reusable dishes. Besides the 1% lead contamination in a printed object is imho absurdly too high (the nozzle shouldn't even have 10% of lead and abrasing entire *grams* when printing just doesn't happen). Other chemicals in the pipeline *might* be an issue, but those are likely on equivalent scale and thereby mostly harmless. It's not like other filaments add highly toxic nerve agents as solvents or anything like that.

@@MyTechFun Oh, you are absolutely right! I forgot, that you included this in the video back then. I understand that you cannot officially endorse it, but out of curiosity: Would you share your personal opinion ("off record") on whether lead and other remaining contaminants in the print head are a significant issue?
