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

[@ChazBword]

This channel needs to be boosted in our community. He's amazing.

[@AJLaRocque54]

Couldn’t have said it any better.

[@swalshy]

would be interested to see the bacteria test results vs. a store bought food safe plastic and have them run though a dishwasher rather than boiled.

[@MyTechFun]

Hm, maybe next time when I visit them, I'll ask my colleagues to repeat the test

[@sched75]

Thanks for your scientific contribution to the community. This is refreshing to have objective data about 3D printing. It would be great to repeat the bio test after using a washing machine on the cups.

[@dinosoarskill17]

Donated so the wife won't be out of a thermometer for too long. :p thanks for the information, as always

[@MyTechFun]

Thank you so much! People like you keeps me motivated!

[@spongecounter]

Excellent info, I had no idea this stuff existed. I will have to try some of this filament.

[@MyTechFun]

I also got something similar from PETG, video coming up, probably in January.

[@ardacakko]

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.

[@Krazy0]

Epoxy coated Nonoilen is probably the best solution, and I can feel safe using it for molds and utensils.

[@HASSTL]

I really enjoy the informative videos that you post, totally professional 👏

[@sierraecho884]

This material is awesome, it is perfect for cookie cutters, water bottle driers etc. everything useful which can be placed into a dishwasher.

[@avejst]

Wow, impressive filament Great test of the filament Thanks of sharing your experiences with all of us :-)

[@YeetDisDude]

Such an underrated channel

[@sierraecho884]

This is a very interesting video, I have complitely missed this video so far. Your videos are great.

[@SomeoneAbstruse]

Has there been conducted a similar test regarding some (or any) resin filaments? Very good and scientific video. Great as always. 👍

[@MyTechFun]

Not (from my side). But I know that some resins are used in dental purposes, so there is a solution, I hope somebody will investigate it deeper soon (or maybe I have to do it, but not in near future)

[@damiansierocinski16]

@@MyTechFun as far as I know those resins are used only to prepare casting molds for dentures and etc. to be made in final material. But I might be wrong at this

[@dinosoarskill17]

Crafman (i may be spelling it wrong) has very recent videos of him testing high temp resin for plastic injection molding

[@LoganKale-i4d]

The food safe filament can be treated after 3d printed to protect the build up of bacteria and not deform the printed product.

[@Beakerzor]

THANK YOU for making these food safe videos

[@ChazBword]

I LOVE YOUR VIDEOS!!!!!!!!! love. You are so great in explaining things.

[@thiagosannafreiresilva4366]

Very interesting material! Thank you for testing it.

[@ruudb72]

Niec video and good info. Thanks.

[@ThePhilbox]

Hi Igor! If you are doing another round of testing I have some very nice ABS+ from a Canadian company... Its called Sparta 3D. Id be happy to send 100-200g in the mail so you could include it. It prints so nice that it makes me suspicious. haha. Thanks for all your time and efforts. I always learn a lot.

[@MyTechFun]

Currently I have too many filaments waiting for the testing.

[@ThePhilbox]

Very interesting...thank you!

[@Robothut]

Does the Nonoilen filament paint , sand and glue like PLA. Thank you for this great video.

[@MyTechFun]

Sorry, but I didn't test that so far. I just quickly tested now, the sending is OK, but not sure about painting and gluing.

[@ThePhilbox]

Thanks!

[@ARandomTroll]

I tried to use PP for amateur chemistry stuff once. Tried sealing the surfaces by melting them with a blowtorch/ candle with mixed results. you might want to investigate this option.

[@klave8511]

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

[@MyTechFun]

Yes, it can survive dishwasher, tested but not measured (bacterial test)

[@kay6736]

Would boiling in salt water or some other method help drive the values down to 0?

[@gladiatormechs5574]

are containers that originaly held drinkable fluids like jugs of green tea considered AQUARIUM SAFE for remelting... and re used as AQUARIUM DECORATIONS.. ?

[@hokazshinitzu9042]

Nice Video

[@NicksStuff]

I assume 8 is better than 35 but how much? What's the limit for food consumption?

[@MyTechFun]

Both are low values (if you use it emmediately after cleaning) but I am not happy with them. If any of bacteria survive they will again spread. If you take a look my other video, 0 CFU, coating with epoxy is 100% cleanable

[@barderino5673]

What if.......the print is actually washed in a washing machine ? Because the brand say you can put it in the dishwasher without any problem so i think that a normal 1:30h washing program can remove every bacteria

[@MyTechFun]

It can be washed in a dishwasher machine, but we didn't do the bacterial tests with this cleaning method.

[@barderino5673]

@@MyTechFun I'm confident to say that in a dishwasher with 1h cleaning will be bacteria free ..... maybe not for spores... I'm not a soap expert but i think those dishwasher soaps have bleach for them too

[@thetinguy]

can you test in a dishwasher machine with the dishwasher detergent. ive heard the detergent is very hard on plastic.

[@MyTechFun]

I have some objects which I am already washing in dishwasher too. So far I coudn't notice any deformation on it (few months now, washed approx. 1 per week)

[@gnydick]

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]

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]

I agree, and I already discussed this process in separate video (linked from this one) kzbin.info/www/bejne/onfXfnylZZWnnLs

[@nightclaw999]

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.

[@nightclaw999]

@@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?

[@gnydick]

@@nightclaw999 yes. You can't wash toxins out of the plastic. They're infused.

[@SplitPhotography]

So is it food safe or not? What is considered food safe? 0 CFU? Not very clear in the video.

[@MyTechFun]

Let's say, after boiling, food safe for few days only. Since not 0 CFU after longer period bacteria colonies will be multiplied..

what do you think of using PLA or any other common filament without any post processing for baking? cookie cutters etc.

[@MyTechFun]

I did more detailed video about that topic: kzbin.info/www/bejne/onfXfnylZZWnnLs 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]

@ 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 ...

[@Drmaxter]

Have you tested this filament coated in epoxy resin? That must be the best food safe combination possible?

[@MyTechFun]

Epoxy tested, but not this one

[@SplitPhotography]

Max 50mm/s ?! Very low, did you try higher speeds?

[@MyTechFun]

Maybe 60 mm/s but for infill or similar. I use default "quality" settings in the slicer.

[@SplitPhotography]

@@MyTechFun thanks!

[@o1ecypher]

good morning

[@WillGiam_3D]

How is it possible to have still bacteria on a boiled object?

[@MyTechFun]

I was surprised too, but this is too short boiling. For full sterilisation you need to boil 20 minutes officially, but usually 8-10 min is enough (this is what they told me on University where they tested it)

[@billygate4063]

gonna use this filament + food safe epoxy + stainless steel nozzle to make 3d printed mugs

[@billygate4063]

please let me know if I should add anything else to my process

[@Drmaxter]

How is the result? Still using the cup?

[@bassam.2023]

What is the CFU number that you get when you l a glass and a plastic store bought cup? This video has left me hanging...😒

With Epoxy and injection molded parts it was 0 (check my food safe 3D printing video, link in description)

What surface? Raise the temp of the bed. Try hairspray or glue stick.

[@Felipeh999]

@@MyTechFun I have a Biqu B1, with the original spring steel sheet bed. I've never had any adhesion problems with PLA or PETG, so this filament is kind of frustrating. But I only have a small sample of it, so I won't have to deal with it any further. Tanks for the tips, your channel is amazing!
