- In this episode of Design for Mass Production 3D Printing, we push the boundaries of FDM 3D printing, as we tackle the ambitious challenge of creating a 3D printed water bottle, in an attempt to prove that virtually any manufacturing limitations can be overcome by carefully planning and designing with intention.
We address the limitations of FDM printed parts not being food-safe nor waterproof. Discover how we've managed to design around these limitations and redefined what's possible in designing and manufacturing 3D printed products.

I print a case for a Raspberry Pi. I put a Raspberry Pi in the case. Behold: I have printed a computer.
😂
You mold a water bottle. Behold. You made water
I think you have missed the point. You can create a unique design that holds water which is a water bottle. There is an element of resourcefulness, but that is the benefit of rapid prototyping which can be shifted straight into production. The Raspberry Pi foundation is equally as ingenious in it’s approach to give you amazing compute boards.
@@Giftedmike359 I think you're missing the point. This is total cop out. When people talk about printing food safe items, this is not what their talking about at all.
@@arthurdiamondhands474 It doesn't really matter what people are "talking about". it's a food safe bottle which contains water at the end of the day. Manufacturing is about overcoming challenges and delivering an end result, not simply being a purist at the expense of product quality.
I love the videos, but it was said in the intro that we were going to debunk the statements that you can't 3d print a watertight and food safe product. We still didn't do that we printed a case for such a thing. I was hoping you would talk about the "food safe" filaments and printer parts.
This is actually little different from using a coating on things like food bowls, etc. There's a potential porosity with 3D prints...so you're given suggestions for coatings like you'd put on things like wooden bowls, etc.
That's not cheating any more than what they did there. It's still a bottle. It's still mostly 3D printed (Armor for a fragile bladder constitutes a bottle as a complete assembly because it's the whole product that counts.).
What you're looking for is a silver bullet...which isn't going to be the case for any Additive system on the planet. Sorry...
Your takeaway for this is the biggest takeaway: "No process is inherently limited- you are limited by your ability to engineer for that process"
I (and they) can't help that you're not engineering for it right. ;)
@@frankearl9285
I just think it's a little disingenuous for them to show the water bottle and say "Right here is a fully FDM 3D printed water bottle that is fully waterproof..." when in reality what they printed was a case around an existing product that is waterproof, not something that is "fully FDM 3D printed".
From a design perspective I think it is a fantastic idea and great to show people, but click baiting that you can 3D print food safe and water proof things while showing something like this is a bit dishonest.
@@frankearl9285A debunking of a general issue (food safe) was promised but a viable solution for a specific issue was provided (water bottle). The solution isn't directly transferable to say making a cup.
I speculate that many of us viewers are more invested in 3D printing than the intended audience. Which is people who want to get parts printed with Slant3D.
Well, you can print bottle out of PP filament, but it's not a simplest plastic to print and for being really food safe you have to meet Cleanliness in Manufacturing requirements, so it's kinda pointless action
I printed a food safe measuring cylinder out of pla. It is water tight, and goes in the dishwasher. It could be better but good enough. I was expecting a final different layer in his water bottle or tests to demonstrate it was safe. Instead he printed a water bottle case, not a water bottle.
Well you made a water bottle casing. The actual function of the water bottle (containing the water and dispensing the water) is being performed by the bought product enclosed in your case, not what you printed.
Just like cardboard milk containers
@@slant3d not at all. one is a one piece container plastics and Cardboard fused into one item.and the other is two separate containers bladder doesn't need plastic cover... their very similar but not the same.
@@slant3d Dude come on. Quit being difficult. We all know this is not what people mean by food safe 3d printed.
@@slant3d uh, no
@@slant3d No. The cardboard milk container is an object that is the sum of its parts. Without the cardboard that ultra thin layer of plastic will pop like a water balloon. Without the layer of plastic coating the cardboard would get soaked and disintegrate. All of its parts are necessary for its basic function.
Whereas the water bottle inside the case you made doesn't actually need the case to function. I have a few of these flexible water bottles, they have lasted for years without a case. The case would actually detract from their utility since one of the benefits of them is that they fold up when they are empty. But your case is going to remain rigid and continue taking up space.
thinking quickly, dave constructed a water bottle using only a 3D printer, a cad software, a computer, some PLA plastic and a water bottle
You start the video basically saying "people say that 3d printing isn't food safe, well that's false" and then do not make it food safe. You shelled food-safe thing. That is a great idea, sure, but that's not the initial statement.
When does post processing stoping being post processing. Carboard is not waterproof either until a coating is put on it. You have to engineer solutions about the end goals.
@slant3d That's a play of word, you clearly made expectation of a way to make 3d printing food safe while you just made a case for an already existing item. the idea is actually good, but hiding a simple case behind an "engineer solution" excuse is not really honnest.
And i suspect you took water bottle because it's the only example either working or straight silly :
"Yeah you can make food safe box, you just have to buy a plastic box and 3d print around it"
"Yeah you can make a 3d printed fork, you just have to buy a fork and print the handle"
Idea is cool, but the clickbait is strong and justification despicable, honnestly.
@@maxoux33 hes deleting comments now too
@@slant3d Except your statement when showing the product is "Right here is a fully FDM 3D printed water bottle that is fully waterproof..." which is 100% false as you didn't FMD 3D print the off-the-shelf bladder you placed into the shell.
From a design perspective I think it is a fantastic idea and great to show people, but click baiting that you can 3D print food safe and water proof things while showing something like this is a bit dishonest.
@@lethargicpuffin2243 (I imagine) you’re having that reaction because you’re used to thinking of a water bottle as a single part (minus the cap). A big part of the message of this series is that if you think deeper about what you really need, you can find ways to make seemingly-unprintable products using 3D printing - and they do that again here.
I was kinda hoping that there would be some discussion about whether the printing process itself could be made more food safe. Over-extrusion to fill in gaps, using food safe PETG, etc. If that can't be done - perhaps something like food safe spray-on liners to allow the interior to be any shape you want. Printing a shell around an existing food-safe container - kinda feels like cheating. Yes, of course if you just make a shell that's okay.
i was thinking about the same, the approach of trying to reinvent something just for the sake of it doesnt feel right, i think it would be better to find those gems that are only 3d printeing suited, and add a ton of value, i dont think this kind of bottles add any value to be honest
Same here, was hoping to hear about food safe and PLA.
I really wish I could post links here. But a 3D printing group I am in on FB (Just called 3D PRINTING now with 275K members) has a member who posted their paper on this topic. Essentially that yes, 3D printing is food safe. It is not "certified" safe but they expect it eventually.
From the article: “Plastic cutting boards seem to have more contamination than 3D-printed parts. More CFU’s grew on the petri dishes from a plastic cutting board that had been washed with soapy water, than 3D-printed parts that were washed with the same method." Matt Thomas. "IEEE 3D printing and food safety" IEEE (2023)
It is about a 6-page read, shows their cleaning and testing methods and which filament types they used.
@@RoseKindred I read it, great paper.
Agreed this video completely side steps the question. The 3D printed parts aka the bottle housing isn't food safe. Nothing printed was made food safe.
It's a great real world solution but if it was a maths problem, your maths teacher would give you a 0, because you answered a question that want asked.
In general this channel is great but I think it does printing a disservice to make false claims. Using this video’s arguments almost any material can be “waterproof and food safe” by placing a water pouch inside. Flank steak? Yes! Woven hair? Yes! 😜
So...what would you call using a coating on a food safe bowl or cup? It's little different.
@@frankearl9285 I wouldn't call it making a food safe cup if what I'm acrually making is a cover for a food safe cup. Some of us are weird like that.
You can also 3D print a fully working smartphone, just print out a phone case and slap it on a smartphone, boom, fully working smart phone. Perfect idea for the next video. 👍
Remember the Dave The Barbarian meme?
Thinking quickly, Dave made a Megaphone only using Some rope, a squirrel and a megaphone
LOL
This is a bit deceptive. Technically you did print a water bottle from a certain point of view, but you just 'bought' your way out of the problem.
We designed our way out of the problem. That is what engineering and product design is.
@@slant3dNo, that is not engineering a solution. It is circumventing the problem using an existing solution without using 3D printing technologies. Disappointing video.
@@slant3d If we have emissions issues and our cars are polluting, why don't we invent something with 4 wheels that's not a car? We could build an engine into it so it can move.
I don't want to take the effort in designing something, that's never easy and I do think that for some people this might fall into a niche solution for their needs. But I agree that we shouldn't call things what they are not
So if I print a case for a banana have I actually printed a banana? No, neither did you print a water bottle.
If you put water in a water bottle you created water?
@@slant3d clickbait
@@slant3d If I print a case for a water bottle, I've made a water bottle case, not a water bottle. It's akin to knitting a water bottle holder. You didn't knit a water bottle, you knitted a water bottle holder.
Another idea: Print the water bottle in one piece then pour some kind of epoxy/resin/urethane inside which is food safe? Roll the bottle around to completely coat the inside, pour out the excess, allow to cure, done? I feel like that would be much closer to a fully 3D printed water bottle than this solution. As long as you could find a flexible product that doesn't degrade for many years, it could be an affordable and long lasting solution. I'm finding food safe urethane resins for indirect food contact, but not sure if there is anything home brewed that is technically 100% food safe. Hmmm.
That would work. The problem is that it is not viable for mass production. The additional processing and resin material would be too expensive.
@@slant3d Yeah I hear you. I'd definitely like to see a better solution than bladders though. Not that there isn't useful info in this video.
I thought this video would mention some of the food, and dishwasher, safe filaments e.g. nylon 680 from taulman3D and slicer parameters to produce watertight models. I was a bit disappointed to find it's just a way to hide an existing watertight bottle within a 3D printed shell.
Just like cardboard cartons
Suggestion for future video with school starting soon, a lot of kids will change their backpack for new ones because their clips are broken. You can find replacements in thingiverse or printables but I would really like to see something design for 3d printing that would be cute and durable.
Best April Fool's ever! Good one, guys, got me!
But how do you clean the inner bottle?
Have to bring it to the dry cleaners
Open the cap and put some soapy water in there… or take the two halves apart and clean it.
@@bozthescrewup410 that doesnt even work with a regular glass bottle. Needs scrubbing or.. a pressure washer?
@@bozthescrewup410 that doesnt even work with a regular glass bottle. Needs scrubbing or.. a pressure washer?
@@JonasBuechnerArt how does anyone clean a camelback bladder or any other thing like that?
Interesting idea. Was wondering how you were going to deal with cleaning the inside. A bladder is great way to make this work but technically isn't making a 3D print food safe because you require a non-3d printed bladder. Still cool idea. Just a bit clickbaity with the title.
I mean, that's a case
A waterbottle is a case for water
@@slant3d a cased case then
I wouldn't call this a "water bottle" its a water bladder holder or water bladder case, I think a "bottle" is a container that can actually hold liquids. Its like printing a phone case and putting the phone in it and saying you 3d printed a phone. A case, is used to protect the contents within. Which seems like what this is doing exactly
Just like how cardboard milk cartons work
@@slant3d agree to disagree
@@slant3d lol you sound silly to be honest. That's not how a cardboard milk carton works. A cardboard milk carton actually contains milk. It is not a shell that encases a container that contains milk. You couldn't walk around with just the milk without the milk carton. You could definitely walk around with that pouch with water in it. Therefore, the shell you made is not a water bottle. A milk carton is a milk carton.
I have been looking to do a similar thing for a mug but I can’t find the stainless steel insert that I wanted to use and I’m a bit afraid to look into a one off machined part because I don’t have any real budget for this project.
Ok
I like the approach to get around the food safety and leakage of a water bottle, but say I wanted to make a coffee mug or something. How would I take care of the food safety issue of filament and the fdm process to make a plate or a cereal bowl?
Also does the nozzle contaminate at all, does that have to be food safe?
I printed one for myself like, 2 years ago. I realize it slowly leaks water compared to a bought one, and water tend to mould faster, so I used that cup for pen washing instead.
Wow if you reached any further you'd be touching the moon
i feel scammed by the thumbnail and am not happy about it.
Kind of hopped I would learn about food safe 3d printing process.
How do you make the outside texture?
On the flat surface
It's a setting called fuzzy skin in most slicers.
Think you could rebuild those plastic woodworking jigs, like pockethole jigs etc?
Is PLA reactive to another substance like gasoline, alcohol ect... if the bottle can hold liquids with out insert ani container inside?
Would it be feasible to fuse a polypropylene film to the inside of a printed bottle like this instead of using a third party water bladder?
Absolutely. Just like cardboard cartons.
I think it would be a good point to show the prices of plastic injection machines and the prices of molds and the capacity along with the prices of 3d printers for a 3d farm for the same capacity. The first thing that catches the eye is that you can start with a very small number of 3D printers and very little investment, so if the business starts - expand the number of printers
Can you make custom air intakes for cars and even intercooler piping?
Print a shell, put all that inside it, there you go.
Another approach could be printing the bottle whole and pouring in an epoxy or something similar and spinning it to form the food safe lining, then letting it cure.
how would you wash that bottle with the inlay?
Like anything else. The bladders can be washed with a bottle washer like any other bottle. It's just that they generally are more fragile than a water bottle normally is because they trade packability for durability there.
For this discussion, lets look at the problem of nesting. An aluminum can takes as much space to ship EMPTY as it does to ship when filled, and sealed. A water bottle shipped empty, then filled, takes a lot of transportation expense to get it to the filling station because it is not nestable. So let's take this concept, and design a nestable solution. Shipping empty containers at some tiny fraction of the volume, until filling is where the design can shine. Once filled, it will be heavy, and take the volume it takes.... But let's reduce the pre-filling volume. So let's say the inner liners can be flat packed and shipped tightly. Then, lets say Slant 3D's two halves, can be nested to each other, and flat packed tightly. THEN, at filling time, the liner and two halves come together, and take the volume they take. HUGE savings on shipping empty containers. WIN, Win, win.
That is a great point
There could be money to be made with a 3 part, customizable, nestable, liquid storage vessel.
@@slant3d
The video should be called: Can you print a water bottle vessel? because you didn't print a water bottle.
I think a dead blow hammer that lasts and has some advantage you could only achieve with 3D printing. Would be pretty challenging.
already done. Check out some of our earlier videos from a couple months ago.
Beyond cleaning and waterproofing, it has to do with the material your nozzle is made of. If it's a standard brass nozzle, or many other types of nozzles, it can't be considered food safe because of the potential leeching into the product.
Incorrect
@@slant3d says incorrect and provides zero explanation bro face the facts you made a water pouch case and pawned it off as a water bottle its not like a milk carton, and since you love to use that analogy to hand wave the fact this video is 100% click bait and has zero substance let me ask you a simple question: can you take the liner out of a milk carton and still have the same product the answer is no. the lining of a milk carton is fused to the cardboard making it one object your idea is a case just face the facts and be honest with people
honestly, this uses more plastic than just using a plastic water bottle, the soft TPU or silicone water bottle is flexible but is made from more or less material than a rigid petg/recyclable one. And even the rigid one you can just squish it a bit once you're done.
This gets rid of the advantage of being able to squish the blader bottle. It's occupying the same space while also not holding water by itself.
But I also think that it's a neat idea and we actually need more of these. A good step in the right direction. And even if it's not a substitute of said existing bottles, it's an invention that someone will probably find useful and necessary.
So the conclusion is you can't really FDM 3D print a water bottle but a case around a bladder to make it appear as a water bottle.
Pretty disingenuous to say you can make a food safe, leak free, fully FDM 3D printed water bottle then present something that is merely a case around what actually holds the water.
Thought you'd coat the inside or otherwise, similar to cartons, not just.. put a bought product inside.
It's a nice idea if you want a custom water bottle and want it to actually hold water, but you pretty much lied by saying all limitations of FDM 3D printing are incorrect and saying it's FULLY FDM 3D printed when it's very clearly not.
But if you insist on saying it's a fully FDM 3D printed water bottle, then the same logic can be applied by making a water bottle entirely out of paper and putting a bladder inside it.
^this, 100% this, I usually like the videos on this channel and was expecting some technique for slicing or modelling on this one.
Instead we got snake oil level marketing for a video that should be titled “how to 3d print custom water bottles” that starts with a disclaimer saying that the bladder is in there.
You also can't make a cardboard milk bottle without adding carboard around an internal bladder. They just fuse theirs to the outside. We did not.
@@slant3d They don't add cardboard around a bladder because there is no bladder, it's a liner, not a separate thing they buy and fuse together. Why didn't you use a liner? it would at least make your argument valid.
And looking at how they're actually made, seems like they add the liner to the cardboard, then folded and sealed.
If your goal is to have a cool water bottle, that's one way to do it. If your goal is to have a cheap water bottle, using the existing molds would seem to be better way to do it.
3D printing has not molding or startup cost. But the same scale and unit cost.
@@slant3dwhat's the cost of that bladder you bought to put inside the printed case? I doubt it's any cheaper than a simple pet bottle
OK. That was more of a water bottle holder than a water bottle, but still a good lesson in not letting the nattering nabobs of negativism prevent you from doing cool and profitable things.
Honestly I know this might be out of order but they were able to somewhat water proof 3d prints for bobbers surely they could build off of that.
Takes drink & struggles to say "yeah" as he sounds like he choked a little.
Jk, but lol
lol
why do i keep watching these videos i dont even have 3d printer nor i am going to mass production anything
So when you showed that bottle with the curved geometry around it, there's an application for that design that was not mentioned.
How many of us have had a water bottle or soda bottle or can especially outside on a humid day, And it just drips into your cup holder, desk, etc with condensation?
Geometry like this can insulate it to the point where condensation is not an issue and your drink stays colder too.
So you need another water bottle to make a FDM water bottle
Springs. Would love to see effective long lasting 3D printed springs
Didn't debunk waterproof or food safe or a 3d printed part by using a bladder internally....
Just like a milk carton
@@slant3dyou called it a "fully FDM 3d printed water bottle," right after your speech about debunking the idea that fdm 3d printed parts can't be food safe or water tight. then you led us around by the nose for a good portion of the video, expecting a way to make a "fully FDM 3d printed waterbottle" completely foodsafe and watertight. that's not what you delivered.
conceding the nonsensical idea that it's "just like a milk carton," this still isn't what you promised. you promised a functional... foodsafe... "FULLY FDM 3D PRINTED WATERBOTTLE," which, being FULLY FDM 3D PRINTED shouldn't contain components that don't meet the definition of FULLY FDM 3D PRINTED.
the word for this kind of claim is called a "lie."
I think most people expected be able to print a water bottle at home right now after viewing the video - me included.
However, the water pouch solution makes perfect sense in the context of manufacturer: buy a few thousand pouches for close to nothing, print the halves and assemble everything with minimal human intervention. Without the pouch, you would need an expensive post-processing to apply multiple coats of some food-safe resin, QC the application, test watertightness and you'd be responsible to ensure your product is food safe. Basically, with this solution you outsource all the trouble to the pouch manufacturer.
I'd love to make a food safe water bottle *from scratch*! So if anyone has a non-pouch solution, I'm all ears ;)
There is no problem in making a shell that holds the pouch. That's great. What is not great is to say that people thought you couldn't make food safe water tight water bottles, and you have proven them wrong. No you didn't prove them wrong. You didn't make a water bottle. You hade a shell that contains a water container. You could make a fancy shell that you would slip a coffee cup into as well. Would you say that you also just made a coffee cup?
How do you clean it?
How do you clean a regular water bottle?
@@slant3d dishwasher safe?
I was hoping for tips on making 3d prints more water-tight.
This is a clever solution. But you chose to be very misleading about what was really being made
Dude! that is cheating! ahaha
great idea!
Engineering and Design is all about cheating
@@slant3d yes, it was an compliment
Totally outstanding, thank you for your Insite and your willingness to share your experience.
Is it possible to use a resin 3d printed bottle as a perfume bottle, if yes what type of resin do i need to use
Your 3d-printer part of the product isnt food safe. It doesnt contact food. That is as if I resin-coat a 3d printed spoon - the 3d print isnt food safe until i added something to it.
These nice sandy texture or finned desing are also impossible to wash.
Also you proved nothing because you didn't print a bottle but only a water bag protection casing
I guess if you didn't do it, it is because the answer is that you can't print the entirety of a water bottle
Sometimes there's no need to reinvent the wheel.
This channel definitely suffers from square peg round hole syndrome sometimes.
In order to get certain benefit you have to engineer certain solutions.
@@slant3d yes, but this is clearly not a relevant example.
lets see how we are going to transform how i understand bottles today XD
lol
I dare you, say Mass Production 3D Printing again!
😂
What regulations are you going by for food safe?
The same as every item in a grocery store. Varies by country. The US the FDA sets the standards.
Nice water bladder case.
Loved the vid, and i was wondering if there is a way to find the design? Id like to make one and alter it to my own liking. And where did you get the water bladder for the inside?
SBS (Styrene-butadiene-styrene) filament
Interesting. New toy to find some and play with.
Listen, I love your videos usually, and I bought your limited run of filament, but let's be clear. YOU DIDN'T PRINT A WATER BOTTLE! A sleeve/case for a water bottle is just that, a sleeve/case.
Just like cardboard milk cartons. Thanks for watching.
@@slant3d literally nothing like cardboard milk cartons. Think rationally please.
It's literally a water bottle coozie.
You should do these videos and also have the STLs (some free and some paid) as a concept so people can purchase and play around with what you have and iterate from there. I think you did at least two such STLs before. Not sure why you guys stopped though!
He is against open sourcing that's why. Tho, he did say that he plans to offer paid stls in future in his video where he talks about open sourcing in 3d printing.
@@saadqadeer7807 i mean purchasing is on the table
So it’s a water bladder cover
amazing!
Thank you! Cheers!
So it’s just a shell…?
I feel like this solution is misleading I expected it to actually be 3D printed not just encasing a bladder.
It’s a solution but not at all what I expected. When you said 100% 3D printed I assumed you meant 100% printed.
This isn’t the same as cardboard milk containers. They don’t say 100% cardboard.
5:50 is the part you're looking for.
A liner doesn't debunk what you said you would. 3d printing solves many problems, but does not solve this without additional parts. Suggesting so actually reduces credibility of the process.
You did not print a water bottle, you printed a case for a bag that holds water. Your information is completely misleading because you did not print a bottle you printed a case. You make the claim that cardboard needs post processing but you didnt post process anything so its pointless to make that comparison. You made a case for a bag.
I print in Polypropylene which is waterproof and food safe ! In fact PP does not absorb water.
Every plastic is waterproof and food safe. That can change once printed.
Seems like most people expected the print itself to be food safe. That's why I clicked. All I see this TH-camr doing in response to people's disappointment is trying to browbeat them into seeing how actually they ~weren't~ deceived. Accountability-avoiding behavior, gonna hit "don't recommend this channel."
The recurring theme of this channel is printing things that just shouldn't be 3D printed. No, 3D printing is not the answer to everything. Water bottle and golf Ts are a good example. An industrial made blow molded or injection molded water bottle has much thinner walls, doesn't need as much plastic and is 1000x faster to make. 3D printing is usefully for a lot of things, but not everything.
Why not use can liners that are used in aluminium can production?
Print the entire bottle not in two halves, install liner, water bottle done.
If you put an actual water bottle inside two flaps of casing you didn't make a bottle, you made an outer casing for a bottle. The bottles were something you bought into your process.
How would that work?
@@valent_t In the exact same way mass production of aluminium cans are manufactured today.
You cheated.
And I love it.
I did actually print a waterproof waterbottle using FDM 3D printing, unlike what you did in this video. Here are some tips for those who are interested:
1. Make sure you use clean stainless steel nozzle, heatbreak and extruder gears.
2. Make sure you don't use toxic materials with these specific components in #1
3. Check your flow/extrusion multiplier and up it by a bit (5-10% works well)
4. Use food safe material (PP, PET, Nonoilen(btw fantastic material)...etc). Also check that the manufacturer has certificate that these materials are FDA approved/food safe.
5. Print your part and use it normally. You will have to experiment a few time probably to ensure that your settings are ideal for your specific design which I won't explain here. One basic rule though, the sharper the angles you have in your design the lower you should make your layer height to ensure waterproofness.
Bonus Tip: I love using vase mode with thick nozzles/extrusion width(1mm - 5mm) to give you a very strong and watertight bottle/vase design.
Bonus Tip 2: you may want to coat your parts after sanding them with an FDA approved material if you really want to.
Note: I cofounded a 3D printing company since 2016 and I'm not new to this field. My first ever print and experience with 3d printing was in 2012. Good luck to all of you who want to delve into this amazing tech 😊
thank you for making watching this video not a complete waste of my time
Genius !
You're 100% on the money.
"Right here is a fully FDM 3D printed water bottle". No it isn't. What you've made is akin to boxed wine and no one says that the cardboard used in boxed wine is food safe or water tight.
Don't get me wrong though, there's nothing wrong with what you made. It's the fact you're saying you're debunking incorrect statements about FDM 3D printed parts not being food safe and being hard to clean. Then you show a product where no food actually touches the printed part, which is still not food safe and still hard to clean.
Boxed wine analogy on point!
This video is definitely not debunking anything. The title and intro were seriously misleading and the infos were disappointing. Consider my subscription cancelled.
This is how they make carboard milk cartons
@@slant3d But there is no youtube video pretending to make cardboard water proof and foodsafe. Then after 3/4th of the video just glues a layer of plastic liner onto the cardboard.
What I want to say is that your expectation handling of the title and intro was not ideal, don't you agree?
@@slant3dbut no one claims that they made cardboard waterproof and foodsafe etc etc
Just coat internal walls with food safe epoxy!
Not optimal for mass production
@@slant3d I disagree. Regular water bottles are often spray painted to apply branding and styling. The same process can be used to apply epoxy coating (there are epoxy specific sprayers) to your model. It will also work as a glue to bind two pieces together. And boom! You have water tight and food safe bottle!
I find the title and the preliminary speech deceiving and untruthful.
"Fdm is not food safe, nor waterproof, we will debunk that"
Well at no point did the video show that fdm is food safe or waterproof.
The host even calls the 3d printed part a case at some point. Calling the 3d printed part is disingenuous.
It is not a bottle in that it can't hold liquids.
It can be used to form a bottle. But if we were to follow the same logic, 3D printing any part of a car means that you printed a car?
Last argument:if we remove the water pouch, we don't have any functionality of the water bottle. On the other hand, if we remove the case, well we still have a fully functional water bottle.
I am not hating on the realisation, bit call it "make a water bottle using 3d printing" or something.
I can understand titles Bering a bit clickbaity but on your preliminary argument you double down.
It is a shame because the content is otherwise interesting.
right after the "debunking" speech at he calls it a "fully FDM 3d-printed water bottle" which is more than deceiving and untruthful, it's a flat out lie
Hey, I have done this as well. I have hand issues and made a shell for the bag-bottles. I like that fin design.
A bit of a misdirect
Why don't you try looking for microplastics and comment after 1-2 months after trying warm and cold water and other things?
I'll be Mr.Contrary on this. I really liked the twist at the end. Yeah, I was wondering what kind of process dealt with the porosity and all that, wondering how the BLEEP he was going to join those 2 halves together and actually hold anything. But, what I got was a lesson in thinking outside the box... or maybe thinking inside the box ;)
Too many times, we get hammers and everything starts looking like a nail. Multi-mode does not take away from 3D printing, it enhances it. 3D printing can enhance a lot of other processes. It's good to be reminded of that once in a while.
I generally agree, but coming from this channel? This channel is the definition of "when all you have is a hammer, everything looks like a nail". He seems dedicated to trying to persuade people that 3d printing is the absolute best process for almost every application.
If this video, and his bit at the end about how every process has advantages, is a sign of him softening his position than I'm fine with this. But until then I'm skeptical.
This is not a 3D printed water bottle.
well I think this channel shares examples to some specific problems. they share a solution but there can be many others. i like this channel because they inspire.
Bottles do not need innovation. It has been a solved problem since centuries, like playing tic-tac-toe.
disapointment at 5:54
I especially liked this video. The take home from this is that imagination and ingenuity are 2 facets of engineering that are too often overlooked. The futility in all engineering innovations is asking “how do I make this new process/technology to exactly the same as the older process I’m used to and describe in terms of the old process”.
It’s an impossible question, and not one we should be asking. Instead we need to be innovating with new ways to achieve an end result. If that means scrapping massive presses for a plastic bag or liner, or whether that’s swapping my wood working hand tools for a machine to allow me to create in batches, then so be it.
Good summary
dude bit of a cheat man. I was hoping that you really did print a water bottle not just a case for a water bottle 😕
Nice! 3D printed water bottle with an easy clean interior! Well done❤👍👍
Now, for not so impossible, but a useful print request! Ergonomic spoon, without support for everyday use. It will be nice if the handle serves double purpose as a stirrer! Added customization(a name tag) could be a plus!
Word play !
Really word play !
Why to spoil your image by doing this ?
Cool idea. Very misleading video
So I am actually planning on 3d printing some canteens in PET1. With good layer adhesion and maybe a little post processing (heat) it should be both food safe and water tight.
I was surprised, I think a lot of people are about this solution. I would have never thought about this and I love it and I’m glad I saw this now I can make my own custom water bottle.
Enjoy! Thanks
good thing you didn't invest 100k on this
"No Process is inherently limited, you are limited by your ability to engineer for that process " !! The biggest takeaway from your channel.
Thanks for watching
And I strongly disagree with it. I believe every process currently existing is inherently limited. And claiming that you could design around all those limitations is stupid or a lie. Some things just don't work, and you have to choose the right processes for the requirements. Have fun building a rocket engine purely with FDM printing or a fireproof safe with woodworking.
