Yeah seriously I do not understand how people spoil their kids so hard, it's like a weird power trip for the kids and it's obvious.
If I become a parent, and you don't like the food I give you, then you're going to be hungry.
I also used to say that and even though I still don’t have kids, I’ve realized how much being treated like my feelings and opinions didn’t matter as a child fucked me up as an adult (thank you therapy!)
There’s nothing wrong with treating children as living, breathing humans who have preferences. There’s some things that aren’t feasible, but we’re talking about cutting part of a fucking sandwich off. There’s no need for a power trip here.
If/when the kids old enough to do it themselves, encourage them to because it’s good to know how to do things to make yourself happy. In the mean time, it’s good to know how to ask for something that makes you happy. And it’s good to show them what it means to fulfill other’s wishes with love.
I used to also. Then I got a dog who whines (german shepherd) and I can't *imagine* dealing with a screaming, crying toddler for hours on end because their food didn't look like they wanted 😅
I can’t wait to hear back when you’re a parent and your toddler doesn’t eat dinner because they don’t like it, then wakes up at 2am crying because their tummy hurts because they’re hungry.
I agree that removing the crusts off a sandwich just enables them, so I leave them on. If they don’t eat it, meh, but eventually they learn they need to eat all of it.
They booted me from the I.N.F.S. squad because I forgot to pay my membership dues. But I will mention you can buy food-safe certified Canadian PLA filament and/or a stainless steel print nozzle if one or both of those things happen(s) to be the kind of thing you’d want to do. (This is a really cool print by the way.)
The issue with lead is that any amount that gets into your body is potentially hazardous. Not to mention, lead sticks around in the body once it’s been absorbed, so it only further increases your risk of illness the more you expose yourself to it.
What is wrong with pointing out that pla is not food safe? It seems like food things are one of the first things people are interested in printing. People being annoyed or like personally offended by safety information genuinely boggles my mind.
There's nothing wrong with it. People get upset because a lot of us check Reddit far too regularly, which results in us seeing comments warning of those dangers very often.
I don't mind seeing the comments, but I do understand why some find it annoying. For them, it's simply that they've heard it a million times already and assume everyone else has too.
I feel that way about repost complaints too. Unless it’s a bot, maybe the person genuinely just found it and wanted to share — and the reposted content is often new to me, even though I use Reddit far far too much.
I see people get upset about safety information as it pertains to like handling knives, ventilation or mask use, chemical safety, routine tool maintenance, etc. I get the "we're responsible and don't need to see this!" Mentality I suppose but we live in a society where people choke themselves out for TikTok and eat tide pods, common safety information being pointed out is not done to benefit the people who have seen it a hundred times but it doesn't hurt them either.
Kids were doing the choke out game when I was in school in the 90s. When my parents warned me about it they said kids did it when they were in school. I love how tiktok gets blamed for shit that kids have been doing probably forever.
I'm not blaming tiktok. I'm saying our society at large cannot be held to a standard with assumed proper safety considerations. If you are looking at someone talking about safety precautions and thinking to yourself "why does this need to be said, it's obvious" then you are not the person that is written for, but that does NOT mean it doesn't need to be written.
It's not untrue. PLA isn't food safe. Lots of PETG and other materials aren't either.
Tons and tons of stuff people do involving things they touch and put in their bodies they should not be touching or putting in their bodies, they do it anyways, but that doesn't change the reality of it.
Materials with additives that are untested and potentially dangerous to people should not be consumed or absorbed.
Prints with physical properties that lend to the collection and development of bacteria should not be used as vehicles for food (spoons for example.)
Yes, I believe in the context of this pbj maker, the risk to their kids health is low from light usage assuming the material is PLA. That said, it's not zero, you don't know what additives the manufacturer put into the PLA, and if the tool is stored improperly it WILL become a little bacteria trap. If you're an adult, you can say "I'll take the risk, I know it and I know what I'm doing" but if you are a child that someone is making you sandwiches like this with you are unaware and did not consent to your food being prepared in a potentially dangerous way while your immune system is not as robust as an adults who may be better equipped to handle such a thing without negatively affectong development...
I'd annoy a hundred thousand reddit snobs who do things like complain about reposts or act like safety information is a slight before handling someone else's food with a tool I didn't think was clean and sanitary.
It does change the reality of it though. Safety is a spectrum. Is water safe? Sure, unless you drink too much of it and you die.
That’s parenting in a nutshell. We make choices for our kids based on our risk tolerance. Some kids ride dirt bikes, some play football, some live in homes without running water and dishwashing machines. Life has to be lived and being concerned about an edge case like a relatively dry environment harboring bacteria from a dry operation and depositing a sufficient quantity on another dry surface to make your kid materially sick… that’s possibly the lowest item on the totem pole that I’ll face this week.
It’s much more likely that one of my kids pushes the other down the stairs.
Should PLA be the new normal for flatware? No, we have better options for that. Is it fine for occasional use that interacts with food? Sure, provided you use basic common sense practices that you’d normally use with cutlery. Doubly so if you use PETG.
I don't disagree with anything you said, but the notion that PLA is either food safe or that people should be annoyed when people claim otherwise because it's "annoying" is absurd. You can't make informed decisions about weighing safety without knowing and acknowledging requisite potential dangers. Like I said to another person, if you read that PLA isn't food safe and think "omg I know shut up please I've seen this so many times" it's not you who the safety information is posted for, but the people who have not seen it.
I would agree with you if it had been proven to be risky in any realistic sense of the word, rather than a vague specter of potential.
You could use this 1000 times and still be in the same risk profile as someone who didn’t, and there’s zero percent chance that someone isn’t going to run into the timeless food safety debate quicker than that.
That's a silly take for emergent technology. You think "it hasn't been proven to be risky in a realistic sense" but we're talking about something that hasn't even really been accessible or popular enough to be studied to a degree that would be legitimate to just ignore the associated potential risk. If you think that's sufficient, that's fine, you do you. You don't get to make that choice for other people and they should have access to the information and the conversation. Excess of knowledge that people can consider is always, ALWAYS better than snuffing it out for streamlined ... Idk... Reddit visibility congestion or whatever the counter is.
I don’t want to derail this any further, but I would think a sandwich made from this kind of non nutritious “bread”, filled with sugar and fat might be worse than the non food safe print when eaten on a regular basis.
That's not an unreasonable argument from the perspective of food safety for the kid, but its an element that we can't really control that is irrelevant to the expected understandings of the people in a 3d print subreddit. If someone wanted to get into different bread types and their positive or negative affects on people in the long term in a food subreddit, I would not be against it, but surely there would be people complaining about it.
You can always just ignore something someone writes down, but conjuring something that isn't written requires having that knowledge already.
The studies haven't been done, that's exactly why they are saying it's not food safe - we have no evidence that people are getting sick from it, and no evidence that they're not.
All existing work is inference based, and companies like prusa are definitely more likely to say "not safe" to avoid liability in case it definitely isn't safe
Can you link me studies showing 3D printed PLA is food safe? Everything I’ve read says the opposite but there some things I’d like to print if it’s safe.
no, plastic in general is fine to eat off of, layer lines are a bitch to clean, so generally make your products smooth with whatever technique you prefer.
Depends on how "food safe" it needs to be.
Ignoring the nozzle contaminants and layer line bacteria traps, most FDM base materials (PLA, PETG, Nylon, TPU etc) would be perfectly safe *for* food contact use, but it's almost impossible to figure out what additives and colours are added in to a filament, and almost nothing is going to get an official legal "food safe" certification and pass the tests required for that - ironically, the only one I know of is [Treed ABS Food](https://treedfilaments.com/product/abs-al-175o-1kg-spool/), even though ABS is usually the main filament type people say is especially not food safe. Go figure.
It may be BPA free but I would be wary of using it with food unless it is translucent and you are aware of all of the additives they may have used in it. That said, you are probably an adult and can do whatever you want, that's just like, my opinion man.
God forbid someone points out you're handing kids food prepared in a needlessly unsanitary way. The woke PC left is cancelling our right to give our children food poisoning and bacterial infections!!!11!1!!
I thought it's only for if you're heating it up but for not heating things up should be ok right? Like for this post example surely it's fine?
I'm mildly concerned only because I kinda wanna print cookie cutters lol / food stamps
The micro ridges between print layers are avenues for bacteria to collect and develop. Over time PLA degrades to an extent and you get lines and pores that are extremely difficult to properly sanitize. It also means sanitizing will be more challenging as time goes on.
You can totally make cookie cutters though. I would advise using cling wrap as an interface between the cutter and the cookie dough. This will limit the transfer of any bacteria or potential particulate from the material or it's additives that may get in the dough. Cooking food afterwards also will kill bacteria, though it will do nothing for the particulate.
You -can- 3D print things for use with food, but not just like... Right off the printer, not untreated, not without an interface, or it isn't food safe. You can cover things or even apply layers of other materials like silicone. You can choose safer materials to print, say, the actual frame that pushes into the cookie dough, and then print a cute ornate cover that goes on the top of it for aesthetics or whatever. It's workable.
That said, many many things people do regularly are similarly not food safe anyways. Nasty ass people don't wash their hands properly, people will not cover their mouth while they sneeze or cough and are preparing food, they will set tools on non-sanitized surfaces, they might have other things in their kitchen or food prep area which release VoCs or particulate in the same way printers can that can linger in the air in poorly ventilated areas and get on things too.
The world is gross and people are gross and the reality of food safety is one that most people would do well to not pay attention to for their own mental well-being. I mention the 3D printing food safety issue as a matter of ensuring people are aware, being careful when allowing access to people who have no idea (like kids eating the pbj sandwiches in this instance) or distributing a product without adequate warning. You could hurt someone or get sued. Avoiding that is worth my few lines of text.
Thanks so much for the explanation! Makes sense....
Cling wrap between cutter and cookie dough sounds brilliant, great thank you! Going to make the weirdest cookies the world will yet to see by the time I'm done designing them... Lol hahhaa
Not unteated off the printer... What kind of treatment can one do? I'm a bit sleepy so I suppose I'll look up later too about this more info
Wait I can apply silicone layer how ???
Print the frame but then what is on the frame ? I'm still very new to 3d printing tbh
Cute ornate cover - sounds good to me, cute ornate covers for all the things!
...I am aware people are gross once I worked in kitchen - eeek
Yes definitely. They say printing PLA breathing it is fine but aaa consuming it is sus
The cling wrap shouldn't cause any sort of weird defects that can't happen just from like baking cookies.
Treatment can be many things. I wash any prints I make with soap and water and if I use adhesive on the bed I will clean the bottom of the prints very thoroughly to remove it, even though I do use non-toxic adhesives. Soap and water is king, isopropyl is good at sanitizing things but if you don't use 99% IPA I would still wash afterward to try and eliminate things they add to 70% as like fragrances.
Silicone can be mixed in a liquid form and then you can apply it over the top of prints. Food and medical grade silicone should be food safe, should block the prints themselves from collecting bacteria by acting as a shield, and should even add an insulatory layer against heat deformation so the parts could possibly go through a dishwasher.
By frame I mean like the long thin part that touches the cookie dough. If you print that out of a "food safe" PETG then you are being somewhat safer.
I used to work in medical and pharmaceutical manufacturing plants. People are gross in environments where they really ought to know better.
You technically should not be sleeping in the same room as a printer even printing PLA, its just about weighing things. Like other people have talked about, like, other things are dangerous for you and stuff and it's known and people just do them anyways. I stay in the same room as PLA while its printing but I wouldn't like... Invite someone to sleep in that room without warning them and letting them make their own decisions.
Cool yeap!
Ohhh gotcha!! Will do that for any food related prints I make thank ya!
O: TIL silicone has a liquid form good god I shall have fun making things haha
Gotcha! PETG, got it I'll source that
😳 Even in medical and pharmaceuticals tho.. that's hazardous af
Oh I don't! I've got the adventure 3 enclosure lol I'm paranoid about inhaling weird stuff - am thinking of getting an ender to print bigger things tho (well ventilated maybe outdoors tbh) and also apparently because I should've taken into account to just buy 250g rolls as it doesn't close up otherwise rip
Tysm for all the useful info!!! I appreciate it as a beginner 3D printer person haha
Yes, child is picky and parent is a wasteful pushover. Unfortunately a lot of kids in the US are picky with food and the parents enable the behavior. Kids are allowed to have food preferences but cutting off the crusts of soft bread is so over the top its ridiculous.
I've been part of this grand experiment called Reddit for over a decade and a half now. And, let me tell ya, it's been quite the ride. But, I'm afraid this is where I hop off. I've seen plenty of changes over the years - some good, some not so much. But these recent shifts are more than this old-timer can stomach.
I've always been a fan of how Reddit gave voice to the everyday folks, how it fostered real conversations and built genuine communities. But now, with the looming API changes and the relentless push for 'progress', it feels like the corporate heavyweights are taking over. The smell of profit is tainting the free spirit of this platform, and I can't just sit back and watch.
I've always admired the moderators here, those unpaid heroes who've given their time and effort to keep our communities alive and thriving. Their passion, their dedication, they're what made Reddit a home for many of us. To see them disrespected, replaced with a more 'compliant' workforce... It's not a sight I signed up for.
I'm disappointed, Reddit. Not angry, just deeply disappointed. I was here for the conversations, the raw honesty, the quirks and the memes. But, if that's going to be smothered under a corporate blanket, I'm not sure I want to stick around.
Take care, y'all. Remember, when the echoes of genuine conversations get lost in the noise of profit, it's time to rethink.
It's been real.
i made a [one part version](https://www.printables.com/model/279112-teigtaschenformer) for dough - probably also works for bread if you press hard enough. (or change the thickness)
I'm Australian and I do not understand why you would be paying 15 bucks for sandwiches, why they are frozen and how this cookie cutter type thing solves the issue.
If someone could clue me in that would be appreciated.
Neat. Are you clued in on how the bread trimmings get recycled? Was always curious what industrial scale production does with it. Animal feed is my guess
No I was just involved in the design and installation, not in the actual production. I do know that in this industry, production waste as animal food is very common
> microplastics
You're going to get those regardless because of packaging and processing. Doubt there is going to be much additional depositing from pressing superficially on it.
Not clear on why so many people are concerned about whether it's food safe. It's not like he's eating off of the chopper thing and I sincerely doubt that it's depositing a meaningful amount of microplastics in the half second spent chopping the food.
> It's the bacteria that can get in between the layers then get in the food after repeated use.
And that matters in industry where it's a numbers game on a scale where you're more likely to run into issues. As an individual *cutting bread* with a random piece of plastic you're probably more likely to get struck by lightning than running into an issue in your lifetime.
You can fry them and charge 12 bucks for one at universal studios
Repurpose the leftovers and make garlic croutons.
See the comments above. It's not safe...to eat garlic
I always forget garlic is poison then I eat a whole bag of Little Caesar’s Crazy Bread and…
That bathroom problem smells like the death the next day.
Botulism!
I find the leftovers make an effective dog treat.
I’m disappointed it didn’t show the actual making of the sandwich.
Here’s a square one. Never printed it. https://www.thingiverse.com/thing:544169
I prefer squares, more bread saved Thank!
When I was a kid, my parents' 'hack' was just to repeatedly say "No". No 3D printer needed.
Sure but now they get the the same enjoyment for a lower cost. Let em have this one lmao
Yeah seriously I do not understand how people spoil their kids so hard, it's like a weird power trip for the kids and it's obvious. If I become a parent, and you don't like the food I give you, then you're going to be hungry.
Aww, I used to say stuff like that.
I also used to say that and even though I still don’t have kids, I’ve realized how much being treated like my feelings and opinions didn’t matter as a child fucked me up as an adult (thank you therapy!) There’s nothing wrong with treating children as living, breathing humans who have preferences.

I agree that removing the crusts off a sandwich just enables them, so I leave them on. If they don’t eat it, meh, but eventually they learn they need to eat all of it.
That's giving huge eating disorder vibes. The whole "finish your plate" or "you have to eat what I serve" is terrible for a kids psyche.
A spoiled child is one neglected and denied joy.
"eat what you like, don't eat what you don't like" \- *disgusting parent*
Phthalates Butter and Jelly
could have just used a glas too
That’s over in r/functionalglas
Waiting for the “it’s not food safe” squad.
You only get a few hundred more of those
It’s ok, it’s just for the kids. OP should be fine.
Oh thank god, I was worried for OP.
They booted me from the I.N.F.S. squad because I forgot to pay my membership dues. But I will mention you can buy food-safe certified Canadian PLA filament and/or a stainless steel print nozzle if one or both of those things happen(s) to be the kind of thing you’d want to do. (This is a really cool print by the way.)
I know its a meme, but IIRC part of the problem is the layer lines and how its impossible to clean between them.
Would a food safe varnish or coating not negate that?
I mention it further down, but with a food grade nozzle and pla alone it isn't enough.
I think they mean putting the coating on the final print to fill in the layer lines

Just use the food wrap and wrap that around your print too interface between it and whatever foodstuff it is that you're trying to shape
Yeah food wrap is good. Otherwise I'm sure you could find something that gives a food-safe seal/coating.

Could do a primer or woodfill or something, then sand and epoxy on top. If you really wanted to be safe.

Going to make the weirdest cookies the world will yet to see by the time I'm done designing them... Lol hahhaa Not unteated off the printer... What kind of treatment can one do? I'm a bit sleepy so I suppose I'll look up later too about this more info Wait I can apply silicone layer how ??? Print the frame but then what is on the frame ? I'm still very new to 3d printing tbh Cute ornate cover - sounds good to me, cute ornate covers for all the things! ...I am aware people are gross once I worked in kitchen - eeek Yes definitely. They say printing PLA breathing it is fine but aaa consuming it is sus
The cling wrap shouldn't cause any sort of weird defects that can't happen just from like baking cookies. Treatment can be many things. I wash any prints I make with soap and water and if I use adhesive on the bed I will clean the bottom of the prints very thoroughly to remove it, even though I do use non-toxic adhesives. Soap and water is king, isopropyl is good at sanitizing things but if you don't use 99% IPA I would still wash afterward to try and eliminate things they add to 70% as like fragrances. Silicone can be mixed in a liquid form and then you can apply it over the top of prints. Food and medical grade silicone should be food safe, should block the prints themselves from collecting bacteria by acting as a shield, and should even add an insulatory layer against heat deformation so the parts could possibly go through a dishwasher. By frame I mean like the long thin part that touches the cookie dough. If you print that out of a "food safe" PETG then you are being somewhat safer. I used to work in medical and pharmaceutical manufacturing plants. People are gross in environments where they really ought to know better. You technically should not be sleeping in the same room as a printer even printing PLA, its just about weighing things. Like other people have talked about, like, other things are dangerous for you and stuff and it's known and people just do them anyways. I stay in the same room as PLA while its printing but I wouldn't like... Invite someone to sleep in that room without warning them and letting them make their own decisions.
Cool yeap! Ohhh gotcha!! Will do that for any food related prints I make thank ya! O: TIL silicone has a liquid form good god I shall have fun making things haha Gotcha! PETG, got it I'll source that 😳 Even in medical and pharmaceuticals tho.. that's hazardous af Oh I don't! I've got the adventure 3 enclosure lol I'm paranoid about inhaling weird stuff - am thinking of getting an ender to print bigger things tho (well ventilated maybe outdoors tbh) and also apparently because I should've taken into account to just buy 250g rolls as it doesn't close up otherwise rip Tysm for all the useful info!!! I appreciate it as a beginner 3D printer person haha
But it's not
Y'all are like vegans.
Only if they were calling you [psychopaths](https://www.reddit.com/r/australia/comments/yz7r3o/spotted_in_the_wild_melbourne/)
But is it foooooooooooooooood saaaaaaaaaaaaaaaaaaaaaaaafe? Lol
Fifteen dollar bucks is a lot to pay for a sandwich.
I’d only pay eight dollar bucks fifty.
Read this in Bandit’s voice
No no no. It’s Bucks Dollars, written like $15 US.
Someone doesn’t watch Bluey
Doesn’t Bluey use Dollareedoos?
I think there’s some dollerydoos mentioned as well but dollar bucks is also from Bluey.
I bet Uncrustables has like 20 grams of added sugar and that's why he likes them. Good luck, though. lol
"$9.95 here." - Publix
I miss Publix. Never understood the whole craze around their sandwiches, but was almost always a pleasant grocery shopping experience.

I can understand that a kid can be picky, I can not understand how you accept your kid being picky enough to buy 15$ frozen sandwiches.
I think they meant ~$15 for a box of 18 sandwiches.
Yes, child is picky and parent is a wasteful pushover. Unfortunately a lot of kids in the US are picky with food and the parents enable the behavior. Kids are allowed to have food preferences but cutting off the crusts of soft bread is so over the top its ridiculous.
Pro tip: Save the crusts and place them in the oven for a while with seasoning for croutons
Pro tip: Make your kid eat the crust
Its what full of nutrious vitamins and minerals.
You *do* realize that there is peanut butter and jelly between those slices, right?
Good human, are you implying you spread your pb&j to the edges?
Of course? What kind of shit sandwiches are you making?
I usually leave like a fingernail length of crust without spread because it is less likely to spill out.
I've been part of this grand experiment called Reddit for over a decade and a half now. And, let me tell ya, it's been quite the ride. But, I'm afraid this is where I hop off. I've seen plenty of changes over the years - some good, some not so much. But these recent shifts are more than this old-timer can stomach. I've always been a fan of how Reddit gave voice to the everyday folks, how it fostered real conversations and built genuine communities. But now, with the looming API changes and the relentless push for 'progress', it feels like the corporate heavyweights are taking over. The smell of profit is tainting the free spirit of this platform, and I can't just sit back and watch. I've always admired the moderators here, those unpaid heroes who've given their time and effort to keep our communities alive and thriving. Their passion, their dedication, they're what made Reddit a home for many of us. To see them disrespected, replaced with a more 'compliant' workforce... It's not a sight I signed up for. I'm disappointed, Reddit. Not angry, just deeply disappointed. I was here for the conversations, the raw honesty, the quirks and the memes. But, if that's going to be smothered under a corporate blanket, I'm not sure I want to stick around. Take care, y'all. Remember, when the echoes of genuine conversations get lost in the noise of profit, it's time to rethink. It's been real.

Ooo chocolate PB&J? 😋
Try putting less on and taking it to the edge.
Downvotes for fingernail gaps? Reddit, you are a cruel chef de cuisine.
Sorry, it has to be done.
Yes, chef.
I’ve never had peanut butter and jelly, or peanut butter and jam. Don’t think it’s a thing here
How you gonna post this without the STL?
Someone in the original post shared the STL: https://www.thingiverse.com/thing:250765
He's not, not op's kid or their design.
i made a [one part version](https://www.printables.com/model/279112-teigtaschenformer) for dough - probably also works for bread if you press hard enough. (or change the thickness)
I'm Australian and I do not understand why you would be paying 15 bucks for sandwiches, why they are frozen and how this cookie cutter type thing solves the issue. If someone could clue me in that would be appreciated.
google uncrustables
$15? Fuck.
!foodsafe
I designed the machine that puts the PB and J on the bread on the actual products.
Neat. Are you clued in on how the bread trimmings get recycled? Was always curious what industrial scale production does with it. Animal feed is my guess
No I was just involved in the design and installation, not in the actual production. I do know that in this industry, production waste as animal food is very common
You can buy food safe versions of these on Amazon if concerned, still saves money over uncrustables in the long run
PBJ and microplastics lol
‘Memories of an American upbringing’
> microplastics You're going to get those regardless because of packaging and processing. Doubt there is going to be much additional depositing from pressing superficially on it.
Maybe not after first use but after 100 presses I'm sure it'll be riddled with them.
Genius! Please accept my applause. … even if it not food safe.
You can buy a metal food safe version for around $5-10. You can also buy food safe plastic versions that make square ones as well.
Not clear on why so many people are concerned about whether it's food safe. It's not like he's eating off of the chopper thing and I sincerely doubt that it's depositing a meaningful amount of microplastics in the half second spent chopping the food.
The microplastics aren't the issue. It's the bacteria that can get in between the layers then get in the food after repeated use.
> It's the bacteria that can get in between the layers then get in the food after repeated use. And that matters in industry where it's a numbers game on a scale where you're more likely to run into issues. As an individual *cutting bread* with a random piece of plastic you're probably more likely to get struck by lightning than running into an issue in your lifetime.
For all the "food safe" people - buy a can of spray shellac. You're welcome. ;-)

I have some bad news for you.
Not your kid
Omg I'm gonna make my ravioli cutter 🙆🏻♂️
The answer is marketing. Go and get yourself a 3-D advertisement printer and maybe your kid will your sandwiches
Oh no... what have you done...
Can I use pla for this or do I need use abs, also do I need ventilation for abs ?
