The filter linked has a welded bottom to place on a cup, does not work without heavy modification. I'm excited to try this, for those worried about plastics - I see a "silicone coffee dripper cone" that would solve the problem.
Finally non-traditional manufacturing artisanal grade microplastics directly poured over my morning coffee.
They put the fins specifically to avoid that, what are you talking about
There's still contact though @@GiulioVonKerman
@@GiulioVonKerman Those fins don't matter, water will come into contact regardless unless you pour excruciatingly slow.
Those are the kinds of design challenges I deal with the most. I'm not doing anything near this scale so I can afford the time to seal parts for food safety. I'm not sure how best to do it otherwise
If you're concerned, changing the part to permit a glass or metal insert is easy enough.
I'd probably look for a third party food safe high temp silicone piece? This would also facilitate cleaning, which is the real reason I'd avoid using this at a coffee shop.
Lots of coffee makers are made of plastic though. I'm not sure why this one would be special. And a lot of consumer grade Walmart grade filters have a plastic content already.
Our society doesn't fully appreciate the creativity of design engineering. People tend to think of math and science as the opposite of creativity but that's entirely incorrect. Designing functional items is a different type of creative process that's no less creative than composing music, sculpting stone or painting canvas. The need to create is the same.
True
That's literally the difference between art and design. Art cannot be useful. If a design is useless, then it's just art😋
But Music, art or a few words are protected and you can sue others
But code or engineering you have to pay a lot of money for patent
An old boss of mine said “any old fool can do for $2 what an engineer can do for $1”
I've found the same in coding - the computer science side of things informs how I do things and allows me to better optimize - but there's still an art to it; not all decisions are reducible to the math.
The videos where you walk through how to design for the FDM process are the best. They really get the wheels turning. When I can internalize half of what you demo I feel myself becoming a better model designer.
Thanks. Glad to hear they are useful
As industrial designer I always appreciate your videos, and they helped me a lot in learning 3d printing oriented design, but this time i have to say that product could be much better.
Before getting into this I should clarify that I am a 3D modeler, designer, and drafter. I work with engineers and all manner of people in both a professional and enthusiast setting when it comes to the making of things. While I think this is a neat project, I do not think it is a good product to sell.
I think this is a fairly lazy reinvention of existing products. I assumed what was going to happen was just a recreation of the Mr. Coffee design but in a 3D printed chassis. It's I think lazier than that seeing how this is just an over engineered holder for a filtration coffee maker which already exist and are made out of lighter and more durable materials. You could achieve the same effect with rolled aluminum and some steel rods and make this exact product dramatically cheaper. On top of that I do not see this as particularly food safe given how porous any 3D print is by the nature of its construction. Unless there is a disclaimer on the surface of the model that this is not food safe right out of the print, I would not sell this. Beyond that, you can buy right now an amazon basics copy of a Mr. Coffee for about $12 and you can buy a filter steeper or french press for as much or cheaper than the sum cost of this product, a steeper, and any food safe resin treatment you would have to do to avoid food poisoning. I don't see this competing strongly among other coffee makers beyond pure novelty.
You're missing the point - take a step back. Look at how basic it looks, how oversimplified the design is. Do you think he's really pretending this is an amazing competitive coffee maker?
This isn't a real product, it is an instructional case study exploring optimal techniques to design products for 3D printing, compared to traditional manufacturing methods. He's explaining principles and ideas that you can extend to other projects, where the process is more viable.
This is the case with all of this video series. The spoon, the water bottle, etc. Here, a coffee maker is just an example of a desired geometry with functional constraints.
lol bro stand down it’s just an example
@@spencerkirkhope7397 I wouldn't take issue with the whole affair if it wasn't being sold as a ready-to-print product in the description of the video. Also this is far from a "simple back to basics design" This takes up quite a bit more floor space than its contemporary coffee makers also the making of coffee is at this point a solved science. There are a thousand ways to make a cup of coffee and a lot of them are cheaper than this and the required food safety precautions that are thrust onto the consumer rather than the company making it. I don't think I can stress that latter point enough, 3D printed plastic is not food safe and selling a food product that is not food safe is a bad idea. This would be much more defensible if it was a purely demonstration model for playing with geometries and print angles. However, this video is not that, it is an advertisement for an amazon affiliate link and an STL for a cheap coffee maker that is somehow worse than if I were to go on ebay and buy a used Mr. Coffee.
@@thenextension9160 an example being sold as a ready-to-print product with amazon affiliate links
@@thenextension9160 It's just a discussion, all good 🙂 (plus it helps the algorithm)
This only works if the metal cone is completely solid and only opens at the bottom. If the coffee touches the plastic sides, you'll get more and more bacteria in your coffee as times passes with no way to clean it up.
Yes everyone that owns a 3d printer knows this lol. But then I have not ever heard of one case where anyone ever showed or shared that they have gotten sick or showed any type of bacteria growing on a "non food safe material" or food safe material 3d printed item... its much more rarer than the 3D printers are fire hazard bombs that spontaneously erupt in balls of fire. I actually have a 3D printed PLA bowl I keep hard candies like M&M's stuff like that in for snacking and at best I have only ever wiped it out with a damp cloth every now and then in the last 6 years
That's because the bacteria myth has been disproven by someone who tested it in a lab with bacteria and found that dish soap and water cleans plastic parts just fine because the soap changes the wetting angle and gets between the layer lines and the bacteria washes away. Apparently the biggest hazard is certain specific colors and some of the additives used. There are some filaments that are rated by US agencies for food contact.
@@SoloGamingZA Really? Never heard of one case showing bacteria growth? Funny, because when I search youtube for "food safe 3d print" the very second result is by Igor from My Tech Fun, doing an experiment in collaboration with the university of Novi Sad, clearly showing bacteria growth in the petri dishes.
@@SoloGamingZAfood safety also considers material toxicity: you can buy food safe hydrochloric acid and once diluted it'll taste like citric acid but unlike hardware store hydrochloric it's guaranteed to be free of heavy metals
storing dry foods avoids this because there's nothing to extract the toxins from the material. hot coffee? that's pushing it
Food safe plastic is a marketing term created by the industry. It releases small amounts of chemicals that FDA deems as safe to consume.
Nothing's better than healthy dose of plastic in the morning
the coffee never touches the printed part.
i could bet money that you wear polyester clothing, use polyester matress, pillow and duvet covers and dont even realise all of those are plastic.
@@Altirix_ I was under the impression he was not using polyester
Dude acting like he never drank from a water bottle before lol
@@jksjrgfpsjgr it does 3:32
Coffee is not the only thing you'll be drinking with this one.
"It turned out to be a bigger monster than we thought", the story of building anything
100%. The unknown unknowns of a problem revealed along the way to a workable solution.
I like how you present ideas and information to the community that challenges our convictions and teaches new methods and strategies. Keep it going.
Glad you enjoy it!
Since I first watched one of your videos where you printed an object at an angle I have been using the method for anything that I want to look nice and uniform. Thanks!
Amazing video. You explained your point very well without babbling!
I'll never stop telling you how much valuable are your design tips!
Thank you so much
The design challenges of a single part print as the product present a very fascinating and challenging set of design constraints. Enjoying these Slant-3D perspectives and lessons on (minimalistic) production design.
I love your channel but I honestly cannot imagine anyone with any amount of self-respect buying this thing when Bialetti, Chemex or Aeropress exists
Another great video packed with a lot of useful information as always!! I had a question when printing at a angle as shown in the video at 1 minute in. How do you fine tune settings to adjust to make the layer lines more smooth and even.(What settings show I look at adjusting to fix this, mostly print with PLA). I personally noticed when I print at a angle like this my layer lines are a lot more pronounced.
TRhat's a neat design. I like the style, especially in fuzzy orange.
Thanks
Others are worried about the health risks of plastics, but I just don't want to drink the rancid oils from last month's coffee. I'd really like to see a follow-up on how you address making a surface of layer lines that can be cleaned properly. Have you just managed to make your prints that smooth, do you hit it with a heat gun, do you dip it in a thin epoxy to fill the gaps the way potters use a "slip" for porous clay? I am very interested to learn!
Is PLA vulnerable to the temps from a pour over?
Would be cool to combine it with your spoon design - perhaps a place in the back to slide it.
You print it entirely like that to get around it sticking too much to bed? On my regular 3D printer 2mins after it is cooled it has released itself completely. Also advantage of letting it cool down for few mins is you don't damage/warp the bottom layers when pulling it off hot bed and get a nice finish.
another great lesson in 3D printing design
Thank you! Cheers!
Nice, thank you! Design one that fits K-cups?
The filter you are linking seems wrong. Its has a base that seems to be attached, so won't fit in the Coffee Maker.
I like the design, looks very prusa
What cad software is that?
Isnt the fuzzy skin really time consuming regarding printing time?
About LIQUID touching the sides. I have a screen that I BALANCE on my coffee mug precariously , I put a paper filter in it and not one drop goes outside the screen. Many people have these. Just drop it in this new print, after sizing the print in the slicer , to match.
Can't get away from that first closeup shot with obvious under extension and other defects. Weird.
Btw, can you do a video on the strength gains (tensile/shear) from printing at 45 degrees. I think it makes a massive difference, especially on small features.. Very few videos if any on it though.
Hey man is there an easy way to add chamfer angles directly in bambu studio besides just creating a subtractive object in shape of a triangular prism to just overlay lazily over the parts you wanna subtract to fake a chamfer slopy slope slop? Sloppy
The stl shop doesn’t seem to be working. I would like to give this coffee maker a go.
Try it now. should be up
Love how so many times the solutions is printing at an angle 📐
Slant 3D lives up to its name 👍
So true
How do you address the food safety part of the printer layer lines?
How is it addressed for wood cutting boards
i love your channel! can we get a video about print in place bearings and moving elements?
i designed a print in place bearing recently and used a relief cut to redirect the seam so it dosent collide with the internal surfaces! thats a small trick i wish to share.
Interesting idea. 3d Bearings generally don't have much utility. But they would most certainly be a good demo.
2:18 what software is that? :O Looks nifty to be able to drag and test around like that
That's Shapr3d
I like the concept. As a pour over coffee drinker, I see a problem. How many time you over filled the cup by accident? There is no way to see the level of coffee in the cup.
I think the design could be improved more. The top does not need to be so large. It only needs to hold the top of the metal, so it could be just a simple ring holding the metal cone.
Did you have a script for this video? Because if not it's pretty impressive how you can talk so long so fluently
Thank you. Nearly all of our videos are unscripted
I keep talking about this. Designs will and must change to adapt to this technology. Resin Designs need to change MORE.
To fix the food safety issue, it wouldn’t be too difficult to coat the part with some type of food-safe sealant.
The design and looks are great. What if you don't drink coffee?
Does hot liquid contact with PLA or PETG release chemicals into the coffee? If you're worried about this, could insert a stainless cone part.
Yea, this is also something I am confused about. Is the plastic touching coffee or is the cone fully containing everything?
Coffee on plastic means bacteria growth and staining.
@@vhateg he shows that it is intended to have a separate cone used. Fins separate the main body from the cone so very little is touching. If it does the job well, little to no hot water or coffee should contact the body, and not long enough for things to begin leeching.
@@cloud_tsukamo Maybe your paper filter would prevent that seepage?
important question as you can see coffee dripping along the plastic in multiple shots of the video
@@Phirebirdphoenix I have a screen that I BALANCE on my coffee mug precariously , I put a paper filter in it and not one drop goes outside the screen. Many people have these. Just drop it in , after sizing the print in the slicer to match.
I have a small question - why is the surface finish so bad?
Because their in-house made machines are as cheap as possible an they are twisting it as if they are perfecting the quality and not the cheapness
In reality their service is useless
I probably still would have used PETG just to be extra sure the thing doesn't deform with any heat proximity, but whatever works for you
Your logo looks like a simplified bambulabs logo that even seems easier to print lol dogfooding nicely in my mind.
It's funny because when we desig we do all this without having to think lol
Cool coffe maker
Okay you got me with that title. Let's see what it's about.
Be whicked if you could sla that filter as well so it is completely printed 😁👍
May main concern would be microplastics and degradation: Would it be possible to revise it so that a very thin metal sheet (like 0.1 mm copper for crafts) could be inserted around the cone/plastic ridges area?
Watch the full video
What microplastics? Any source on this?
Copper coffee pots are coated (tinned), probably for a reason, so copper lining would be far from top on my list.
@@kimmotoivanen any source on this? Geez, the plastic part maybe????
Not food safe plastic i am guessing
What material did you use?
And is it food safe?
Watch the full video
Honestly wouldn't use pla in a heat application not even due to intended use but as preventive for unintentionally spilling on it or it falling and potential heat transfer through the metal otherwise its not bad just not necessarily an answer to a problem
My coffee cup is the same size as this
That is awful! It's a huge hunk of very obviously 3D printed plastic that doesn't do anything other than hold the important metal part - who has storage room for that? Ironically a *really* minimal 3D printed holder for that metal cone that sits on top of the might actually be good; perhaps some sort of inverted cone (albeit with much of the material removed?) that could be stored inside of the filter when not in use?
This isn’t about what should be done, it’s about what could be done. Also a good 3d printed part looks and feels better in the hand than a cheaply made injection molded. I am not saying all injection molded parts are cheap. Also the part would probably be like $5 shipped or something. It’s not an expensive part. Another thing is that I can make space for something I like. That part will not take up much space. Please stop hating on new processes just because it’s different.
He’s just showing some of the possibilities and how to design for the process. He’s giving advice for designing models for the process and making the process easier for people to learn about. This is a very good thing that he’s doing.
@@AugiesHobbies what a load of rubbish - now that he's added the Amazon link to the filter it's clear to see that he's started with a sensible stand-alone product that works. And then he's broken it by removing the bottom part in order to add a huge lump of landfill plastic. In the name of "design"? Duck off.
@Jakdaw yeah I agree with you, a Part out of a metall Sheet would be way cheaper for example
I think the actual answer to your question is coffee shops where it fits theme and weight is important. For example, mobile coffee shops? Some consideration should be taken for stacking them during transit, perhaps?
If I can print it at 45 degrees, I will CAD it thusly, if I can't then I will modify it so that it will.
i managed a 3d printing studio, this is the kind of stuff i do with my eyes closed.
The back chamfered area is begging for a cut through handle. Portabiity and reducing material.
4:22 nah: it will still easily break. Drop it on this side and it would propably break. Layer lines are still not perfect.
Ever Drop a coffee mug. That garbage shatters every time it hits the ground.
No need to drop it. It still has very thin layers on the bottom even printed at an angle.
Thats why he just gently wiggles it😂
It will snap if put just a bit of force on top
@@TheRealPowerDoge yeah.. And I dont think a plastic Part should break if dropped. Because people do not expect it to break
Ah ok it's just a stand.
I wouldn't trust pouring water at something with those layers. Especially boiling hot water. Especially when you missed the powder in your own shot.
But is it food safe?
What CAD are you using in this video?
Shapr
You could greatly improve the quality of your video by just having less reverb in your audio.
There are microphones that aren't as sensitive to the sound in the room.
Or just hang heavy bed cover sheet in tge direction you're speaking
That back part is begging to be a carry handle.
Keep plastic away from my coffee plz
This guy could sell rice to the Eskimos
I love your work but I'd argue that 3D printing was not the solution to this problem, functionally or aesthetically, or that there was even a problem that needed solving here. Thanks for the clever design tips though!
Thats how the world changes
@@GiulioVonKerman For sure, but change for the sake of change isn't always a step forward 🙂
Coffee doesnt touch the print right?
Because I believe, then it would be not food safe.
Cybertruck cofee maker. Too many angles in this thing - an eyesore. Should combine it with fillets. These can be noncircular - ending with an edge, so it can be printed nice.
Yeah no way will this hold up if printed in PLA..
And yet. There it is
@@slant3d Yeah use it for a month and get back to me.. It's a good example of some techniques, but PLA is obviously a terrible choice for something that will come into contact with 100c (or near to it) water. Even PETG probably wouldn't be suitable for long term contact to those kinds of temps.. Something like Polycarbonate would work
Yeah... this one is going to be a hard pass for me, and not just because I don't drink coffee (iced tea is my current preference); but most 3D printer filaments are not considered food-safe in themselves, you can't put ones like PLA in the dishwasher as they'll melt from the heat; plastics shed nanoparticles which are turning up all over the human body just from conventionally manufactured packaging (and the 3D printing process affords even more opportunity for that to occur), and of course there's the porous surfaces issue. Also - are we sure that the hot-end of the printers & nozzles are heavy-metal free? Although the exposure rates from handling 3D printed objects with dry skin is going to be low enough to be insignificant, when you're talking about direct ingestion of material that's come in contact with it a different set of variables comes into play.
Guys this is just a demo to show what 3d printing can do, it's not going to be a product you can actually buy
It could be
Mmm hot liquid in contact with plastic yammi❤
just speaking for myself here but this looks like a terrible product, I'd never buy it. looks cheap and non-aesthetic. it's very basic. if water touches the plastic you're leeching nasties into your coffee. who is the target demographic and what's the price?
Good grief, a lot of negative comments! I have an expensive glass carafe type and would trade it in on one of these in a heartbeat. Great idea (and stl price). Unfortunately I’ll have to wait for a readymade version. Thanks.
I'm sorry, but this is a miss. I could see somebody buying the other products you've designed on this channel, but this coffee stand i just can't see. I think a folding, print in place, design to take traveling would better play to the strengths of additive manufacturing.
Make it
I can't tell if this "product" is just and example purely for the sake of the design process or if this is actually being mass manufactured. If the latter, this really shows how low intelligence the business - customers really are.
why every video they upload is like "ya we design oversize and bulky items because this is what we can do with the technology but let convince you that it is a design choice " it is like having a hummer and search for a nail
My dude… your comment is GOLD!
In every video he is not talking about obvious flaws and just jiggling the keys like “THIS IS IMPOSSIBLE WITH TRADITIONAL MANUFACTURING”🤡
Yeah, I’m gonna have to pass on putting hot liquids into plastics and then consuming that liquid…..
But the fins bro
Modern coffee makers are almost all plastic parts...
@@802Garage people in general don't know a thing about materials and chemistry 🤔
Bring back the safe 20th century with PVC and leaded gasoline 😅
Welp, i have a huge respect for what you guys are doing, but there is always some problem i see again and again in the examples you give. Those things have ugly (evenly distributed ugly, props to you) surface finishes. No way someone looks at that and prefers it over injection moulded soft touchy smooth thing. No way!
I prefer a good fuzzy skin or matte surface to the shiny injection molded plastic look of most modern appliances. The only thing I don't like is more difficult cleaning.
Meanwhile I'm sitting over here thinking the regular lines look fine 🤷🏿♀️
